About this Booklet

This is one of a series of booklets aiming to provide definitive lists of hills in Britain and elsewhere. Clearly a lot of people who like climbing hills also like to have lists of them. TACit Tables provide walkers with highly accurate, up-to-date details of hills while being easily affordable and easily replaceable. All heights and grid references in TACit Tables are obtained from the latest large-scale maps. The Ordnance Survey has published large-scale metric maps of almost all of Wales, so future changes should be minimal, but if necessary the lists will be updated.

The details of grid references, heights and drops provide precise measurements of the location and significance of the summits, but convey nothing about distance, topography, terrain or other characteristics of the hills. Maps provide much of this detail, and the tables are intended to be used alongside a map. No attempt is made here to suggest routes or starting points for walks.

About the Hewitts

A Hewitt is a Hill in England, Wales or Ireland over Two Thousand feet high (610 metres) with a drop of at least 30 metres (98 feet) all round. There are 525 Hewitts in total: 137 in Wales, 178 in England and 211 in Ireland (Black Mountain is in both England and Wales). There is a long tradition of climbing 2000-foot hills in England and Wales, and it is safe to claim that nowhere else in the world can match the amount of attention and analysis given to hills of such modest height. At least seven different publications1 have appeared over the years containing lists of 2000-foot summits of Wales. The addition of this booklet to an apparently overcrowded field can be justified by a number of features which make it original and useful:

Some of the previously published lists are out-of-date and no longer available, notably the widely-used list produced by George Bridge1 in 1973. Currently the most accurate and widely used list is in The Mountains of England and Wales Volume 1: Wales by John and Anne Nuttall. This is a useful guidebook but it includes a very large number of hills, and makes no distinction between major summits and minor tops. Many walkers will feel that by using a more selective list they can climb all the 2000-foot summits without having to visit every one of the lesser tops. The list of Hewitts deliberately includes fewer summits than the Nuttalls by requiring hills to have a drop of at least 30 metres (98 feet) all round. Although this is just as arbitrary as the 15-metre limit which the Nuttalls use, in practice it works well, as almost all the Hewitts are worth visiting in their own right, whereas many of the lesser summits do not warrant a detour from a path or ridge. The inclusion in this booklet of the drop from each summit together with the list of SubHewitts (page 11) makes it easier for walkers to decide for themselves which summits they wish to climb, without feeling obliged to take in every one of the minor tops in a round of all the 2000-foot hills.

About the List

Hills are grouped into geographical areas as shown above. The region and section numbers are the same as those used in The Relative Hills of Britain1, which is why the region numbers start at 30. The layout of the list of Hewitts highlights mountains with a drop of over 150 metres (ie Marilyns), which are treated as major summits. Other hills are grouped beneath the relevant major summit, with their names indented. They are listed in order of relative height, so the most significant summits are shown first. Separate groups of hills are kept together. The information is laid out in the following columns:

Metres

This column gives the height of the hill above sea level in metres. All Ordnance Survey 1:50000 maps show metric contours and spot heights. The contours are usually very accurate, but the spot heights are not generally as accurate as those on larger scale maps, though some heights are now being updated as the 1:50000 maps are revised. It is not possible to rely entirely on larger scale maps, as some spot heights are omitted from the 1:25000 or 1:10000 maps. In cases where differing heights for the same point are given on different maps, the following order of precedence is generally used: 1:10000; 1:25000; 1:50000. Any exceptions are indicated in the Notes section on pages 23 and 24.

Feet

The height in feet is arrived at in all cases simply by multiplying the metric figure by 3.2808 and rounding up or down.

Name

Most names are taken from the relevant 1:50000 map. If a hill is not named on this then the name is taken from a larger scale map. Where a hill has a general name and a summit name, the general name is given in the main list, as this tends to be more commonly used, with summit names referred to in the Notes section. As well as notes for specific summits, the following symbols may be used after the hill name:

* Height taken from 1:25000 map.
** Height taken from 1:50000 map.
Height taken from the relevant contour ring as no spot height is given on any map.

Map

This column gives the number(s) of the Ordnance Survey Landranger 1:50000 map(s) on which the summit of the hill is to be found.

Grid Reference

Each grid reference pinpoints the location of the summit of the hill to within 100 metres. Details of how to use the grid reference are given on all Landranger maps. All grid references have been double-checked for accuracy on 1:10000 maps, using a precise technique (a plastic overlay sheet with 100 small squares per grid square).

Drop

This column refers to the relative height of the hill. It shows the height difference (in metres) between the summit and the col connecting the hill to the next higher summit. For some summits this is different to the method used to calculate the drop in earlier TACit Tables. To provide continuity, a second figure is shown in brackets where the alternative method would give a different result.

For example, the drop from Snowdon is given as 1038 (341). This means that there is a drop of 1038 metres from the summit of Snowdon before the ground rises again toward a higher summit. As there is no higher summit in Wales or England, the measurement is derived from the height of a 'col' at NS760781 near Kilsyth in central Scotland, where the ground drops to 47 metres before rising again northwards toward 1165m Stob Binnein (the nearest higher summit). This makes sense mathematically and helps confirm the fact that Snowdon is a significant summit, but it is of no practical value. The (341) refers to the drop between Snowdon and the nearest summit with a 150-metre drop, whether higher or lower. This is Y Lliwedd, and so it means that you have to drop down 341 metres from Snowdon before climbing again to Y Lliwedd. This information is more useful, but feedback from earlier TACit Tables indicated a preference for the drop measurement to refer consistently to a higher summit. In the case of Y Lliwedd itself (and most other summits), the nearest major summit is higher anyway, so the two methods both give a figure of 154m, showing that you have to descend for 154 metres from Y Lliwedd before climbing toward Snowdon.

A more typical example would be Glyder Fawr, where the figure 643 (c 272) indicates that there is a drop of 643 metres to the col connecting Glyder Fawr with Snowdon (the nearest higher summit), but about 272 metres to the col between Glyder Fawr and Tryfan. In this case both measurements may be useful. The second measurement relates to Tryfan rather than Y Garn because the connecting col is higher. The drop from Glyder Fawr to the col connecting it with Y Garn can be calculated by adding the drop figure for Y Garn (236m) to the difference between the height of Glyder Fawr and Y Garn (52m) giving a result of 288m.

A letter c in the drop column means that there is no spot height for the connecting col shown on any metric map, so the drop is estimated from the position of contour lines. It should be accurate to within two or three metres.

The drop figures may be used to calculate how much descent and re-ascent is likely to be involved in climbing two or more hills together, but it is important to note that these figures refer to the minimum possible descent - if the terrain is uneven or there are small intervening summits then the actual descent on the ground will be greater. A map or knowledge of the route may be required for this level of detail.

Date

This column is left blank for you to write the date each hill is climbed, or to enter a retrospective tick. People who disapprove of record-keeping can ignore this column.

About Bagging

Some people argue that climbing hills in order to claim their summits has little to do with the actual experience of hillwalking; that it reduces hillwalking to the sedentary status of stamp collecting or trainspotting. Healthy and harmless but perhaps a little sad and obsessive.

An alternative view is that tables such as in this booklet represent a key, or maybe a door handle. They can help guide you toward your objective just as reliably as any signpost or guidebook. The lists convey more than names and numbers. Every hill is different, every route is different, every day out is worthwhile. Each entry may represent smooth grassy slopes or rough bouldery heather, crags or bogs, sunshine or snow, trees and flowers, birds and rabbits, tumbling streams and shimmering lakes, winding paths and forest tracks.

Sometimes it is easy to forget all this. Lists of hills can help to remind you, for they provide an incentive to get out more often, and guidance about where to go. All you need is a list, a map and a pair of boots. And at the end of the day, you will have more than memories - you will have new dates in your list to remind you where you have been; the icing on the cake. This in itself can be strangely satisfying, providing a sense of achieving something as well as enjoying it. Those who choose to keep records can appreciate and enjoy their walks just as much as anyone else, but their reward is a little greater than for those who are too proud or too principled to bother making a note of which hills they have climbed. After all, enjoyment is temporary but achievement is permanent.

Welsh Hewitteers

The first person recorded as having climbed all the Welsh 2000-foot summits was Edward Moss1 who completed the list on 22nd July 1951. The second person was ED Clements, compiler of The Hewitts and Marilyns of Ireland, who finished on 30th May 1953, though it was not until 17th September 1991 that he added Pen y Brynfforchog7, which was not in the original list. The Long Distance Walkers Association (LDWA) keeps a register of all those who have climbed the two-thousand foot summits of England and Wales or of Ireland. To register, send an A5 SAE to Alan Castle (TT), Glebe House, Ravenstone, Olney, Buckinghamshire MK46 5AR and ask for a claim form. The LDWA do not record details of Welsh ascents only.

The Welsh Marilyns

Hills in Wales with a drop of at least 150 metres on all sides

About the Marilyns

A Marilyn is any hill that has a drop of at least 150 metres (492 feet) on all sides, regardless of distance, absolute height or topographical merit. The list of all Marilyns in Britain is published in The Relative Hills of Britain (Alan Dawson, Cicerone Press, 1992). Since this book was published a number of new Marilyns have been discovered, and some original ones deleted. Details of these amendments are published in an update sheet which is now distributed with the book and is available separately from the author or publisher.

There are currently 1549 Marilyns in Britain: 1213 in Scotland, 176 in England, 156 in Wales and five in the Isle of Man (Black Mountain is in both England and Wales). There are a further 455 Marilyns in Ireland. The list of Welsh Marilyns published here is in most respects the same as that in The Relative Hills of Britain but with the following important differences:

-- As well as the height above sea level (absolute height), the list shows the drop from each hill (relative height), as explained on pages 3 and 4.

-- Details of heights and grid references have been double-checked for accuracy on 1:10000 scale maps and updated where necessary. Where different heights are given on different scales of map, the 1:10000 or 1:25000 scale maps are used, as the 1:50000 maps are generally less accurate for spot heights. Several hills have therefore gained or lost a metre or two.

-- The following recently discovered Welsh Marilyns are included:

32C258846 Mynydd Dinas170 SS760915 c 152

-- Three hills have been renamed: Yr Arwydd to Mynydd Bodafon (Section 30A), Foel Rhudd to Esgeiriau Gwynion (Section 30E), and Edmund's Tump to Graig Syfyrddin (Section 32A).

-- The summit of Bryn Arw (Section 32A) has moved about a kilometre to the north.

Hills are listed in height order within each section. Details given are the same as for the Hewitts. Fifty-three Welsh Marilyns are over 2000 feet high and are also Hewitts so are listed twice in this booklet. Most of the remaining 103 Marilyns below 2000 feet can provide enjoyable walks, and are a good alternative in poor weather when the higher summits are obscured by mist. The smaller hills are also ideal for filling in an odd hour or half day, or for exploring during busy holiday periods when the bigger hills and more popular routes tend to become crowded.

Welsh Marilynists

The first person to climb all the Welsh Marilyns was Rowland Bowker of Portinscale in Cumbria, who climbed his last 22 Welsh Marilyns in a single week, completing the list with Coety Mountain on 11th January 1996. The second person was his wife Ann Bowker, who finished in more leisurely fashion with Mwdwl-eithin on 1st October 1996. Others are known to be pursuing them.

Anyone who has climbed all the Welsh Marilyns, or has an overall total of over 600 Marilyns, is eligible for a place in the Marilyn Hall of Fame. To stake a claim, first climb the hills then contact the author via TACit Press.


Highest non-Hewitt Marilyns

As the highest 53 Welsh Marilyns are all Hewitts, there is little point in listing them again here. Instead, both lists below are limited to those Marilyns below 2000 feet high.

These are the highest 29 Welsh Marilyns under 2000 feet, ie all those between 500 and 610 metres.

Welsh Council Tops

The highest points of the 22 unitary authorities in Wales

About the Council Tops

Frequent local government reorganisation has made things difficult for those who aspire to visit the highest point of all counties. One solution is to ignore the changes introduced in 1974 and 1996 and to stick to the 'traditional' county tops. In England this may be the only feasible approach, as there is a ragbag mixture of unitary and two-tier local authorities. In Wales the position is much simpler as there are now just 22 unitary authorities. A list of their highest points is given below. Some of these authorities could not be described as 'counties' in the traditional sense, so their highpoints are better described as Council Tops. Details given are the same as for the Hewitts and Marilyns. Tops with a drop of 0 metres are not summits but are points on the side of a hill. Some are indeterminate, but the highest point of Merthyr Tydfil is unusual in being marked by a small lake: Pwll Mere. Fourteen Council Tops are Hewitts or Marilyns (or both), and a further six are near the top of one. This leaves just two Council Tops that require a completely separate ascent: Werfa (Bridgend) and Tair Onnen (Vale of Glamorgan).

  2. Snowdon: Summit name is Yr Wyddfa. In summer it can be reached by train.
  3. Garnedd Uchaf: It is often thought there are fourteen peaks in Wales over 3000 feet. There are in fact fifteen. Garnedd Uchaf is the fifteenth that is often omitted, probably because there was no 3000-foot contour on the old 1:63360 maps.
  4. Y Foel Goch: Previously known, oxymoronically, as Nameless Peak.
  5. Elidir Fawr, Manod Mawr, Cefn Yr Ystrad: Disfigured by extensive quarrying.
  6. Tryfan: Often judged to be the only Welsh summit that can not be reached without the use of hands. The two summit blocks, each about two metres high, require some climbing agility.
  7. Pen y Brynfforchog: A relatively new addition to the list of Welsh Tops. It did not appear on 1:63360 maps or in Bridge's book1.
  8. Esgeiriau Gwynion: The name Foel Rhudd refers to the 659m summit at SH895239.
  9. Cadair Berwyn: Highest point is about 300m south of the triangulation pillar.
  10. Moel yr Henfaes: This name refers to a long ridge with the highest point at SJ089369. This summit is referred to by the Nuttalls1 as Pen Bwlch Llandrillo Top.
  11. Cadair Idris: Summit name is Penygadair.
  12. Tyrrau Mawr: Also known as Craig-las.
  13. Craig Cwm Amarch: This summit is sometimes referred to as Mynydd Pencoed. However, there is another top at SH704117 with a drop of less than 20 metres to which the name Mynydd Pencoed may also be applied.
  14. Maesglase: Summit name is Maen Du.
  15. Plynlimon: Sometimes referred to as Pumlumon, though Plynlimon is more commonly used. Summit name is Pen Pumlumon Fawr.
  16. Drygarn Fawr: Height given as 645m on 1:50000 map but 641m on 1:10000 map. No spot height on 1:25000 map.
  17. Garreg Lwyd: Also known as Moel Gornach.
  18. Bannau Sir Gaer: Summit name is Picws Du.
  19. Garreg Las: Also known as Twyn Swnd.
  20. Twmpa: Previously known as Lord Hereford's Knob.
  21. Black Mountain: A unique fivefold summit: Welsh Hewitt, Welsh Marilyn, English Hewitt, English Marilyn, and the County Top of Hereford and Worcester. It is also the highest point of the Offa's Dyke Path. The summit is extremely flat and the highest point difficult to pinpoint. A traverse is recommended.
  22. Cefn Coch: Referred to by Dewey1 as Moel y Pawl.
  23. Craig y Llyn: Referred to by Dewey as Cefnffordd.
  24. Craiglwyn: There is a spot height of 609m at SH728610, suggesting this summit has a drop of only 14 metres. However, this spot height is on an outcrop symbol, not on the lowest point of the ridge; the proximity of 600m contours suggests a col height nearer 600m.
  25. Llechwedd-llfyn: Also known as Carnedd Llechwedd-llfyn.
  26. Trum y Gwrgedd: Should probably be Trum y Gwragedd.
  27. Rhos Dirion: Also known as Pen Rhos Dirion.
  28. Moel-y-gest: The author's first ever hill, climbed about 20 years before Marilyns were invented.
  29. Mynydd Bodafon: Summit name is Yr Arwydd.
  30. Mynydd Rhyd ddu, Craig y Castell, Disgwylfa Fawr, Cefn Cenarth, Carn Gafallt, Mynydd Dinas: New Marilyns discovered since publication of The Relative Hills of Britain.
  31. Great Orme: Summit with the greatest drop (201m) as a proportion of height (207m) other than the three islands. Amusement arcade on summit.
  32. Y Golfa: Golf course on summit, obviously.
  33. Bryn Amlwg, Esgair Du, Pegwn Mawr: Wind farm on or near summit.
  34. Gwastedyn Hill: Twin peak - also 477m spot height at SN982663.
  35. Aberedw Hill: Twin peak - also 451m spot height at SO087504.
  36. Rhiw Gwraidd: Twin peak - also 442m spot height at SO014633.
  37. Long Mountain: Summit name is Beacon Ring. Offa's Dyke Path passes over the top.
  38. Foel Cwmcerwyn: Highest point of Mynydd Preseli, a substantial area of high ground.
  39. Rhos Ymryson: Covered reservoir and several fences on top. Awkward.
  40. Brandy Hill: Twin peak - also 205m spot height at SN146118 (Middleton Hill).
  41. Sugar Loaf: Sometimes referred to as Pen-y-fal or Mynydd Pen-y-fal.
  42. Ysgyryd Fawr: Previously known as Skirrid Fawr.
  43. Mynydd Eppynt: Artillery range covers much of the hill.
  44. Graig Syfyrddin: Summit name is Edmund's Tump.
  45. Bryn Arw: Summit is at north end of ridge, not at south end as listed in The Relative Hills of Britain.
  46. Mynydd y Betws: Road passes within fifty metres of the summit tussock.
  47. Coety Mountain: Previously known as Coity Mountain.
  48. Bryn Brith: Twin peak - also 383m spot height at SH663149 (Pared y Cefn-hir).
  49. Mynydd y Cwm: Named as Coed Cwm on 1:50000 map.
  50. Rhossili Down: Summit name is The Beacon. The only worthwhile hill in the Gower peninsula.
