Snowdon Summit (Yr Wyddfa)

Highlight • Summit

Snowdon (Yr Wyddfa) is perhaps the most ascended mountain in the world, and with good reason. This is a majestic mountain, as is befitting of Wales' highest point.

Its glory lies in the myriad routes to the summit. There's everything from the gentle inclines of the Llanberis path to the knife-edged arête of Crib Goch. The south side of the mountain is generally quieter, with the South Ridge in particular a fine route up. The Miners' and Pyg Tracks are straightforward, classic approaches that enter the incredible natural amphitheatre that holds Llyn Llydaw and Glaslyn.

To get the summit to yourself, rise early and avoid peak season.

Pen y Fan

Highlight • Summit

Chief of the Brecon Beacons and the highest summit in south Wales, Pen y Fan is a hugely popular peak with routes to the top to suit everyone from first time day-trippers to potential SAS commandos. Red sandstone creates its unmistakable layered profile and gives hue to the Bronze Age cairn that tops the summit.

Corn Du summit

Highlight • Summit

Corn Du is rarely climbed alone, but as a peak added to an expedition to Pen y Fan. The climb up is a great one though and the views from the top are absolutely spectacular.

On clear days, you can see all the way to the Severn Bridge and beyond, as well as much of the Brecon Beacons National Park. Be careful in bad weather conditions: visibility can shrink to zero on one of the regular foggy days and strong winds will try and blow your sandwiches away!

Complex and striking, Cadair Idris is the Yr Wyddfa (Snowdon) of southern Eryri (Snowdonia): a honeypot mountain renowned for its imperious cliffs, enticing ridges and pretty tarns. It is a peak shrouded in myth. Its name, meaning ‘Chair of Idris’, derives from the Welsh legend of a giant who created a mountainous seat for stargazing.

Fan y Big might have had its mountain status revoked in 2018 — but don't let that put you off. This is a superb peak that forms part of a classic route through the Brecons, known as the 'horse shoe' or the 'four peaks'. With stunning panoramas on a clear day and the notorious 'diving board' jutting out for those that dare, this peak is well worth bagging on hikes in the area. It is also much less crowded here than on Pen y Fan.

According to mountain classification criteria, to be regarded as a mountain a peak must be at least 2,000 feet (609.6 m) tall and have a minimum drop between the summit and the lowest point of the mountain ridge of 98.4 feet (30 m). While Fan y Big retains its 2,351 feet (716.6 m) height, the drop has been measured at 93.4 feet (28.5 m), making it five feet (1.5 m) under what is required to retain its mountain status.

Jubilee Tower on Moel Famau

Highlight • Monument

Moel Famau affords spectacular views across the Vale of Clwyd to Snowdonia in the west and the English border in the east. Crowning the summit is the Grade II-listed remains of Jubilee Tower, which was built to commemorate the golden jubilee of George III in 1810. Moel Famau is the highest hill within the Clwydian Range.

Blorenge summit

Highlight • Natural Monument

From the summit of Blorenge you get fine views over Abergavenny and the Usk Valley. You may just be able to make out the castle ruins in Abergavenny, not too far from the town hall. From this position, you can also see the Sugar Loaf.

Home to the impossibly-balanced, much-photographed Cantilever Stone, Glyder Fach is the highlight of the Glyders: a world of jumbled boulders and craggy outcrops, soaring sumptuously above Llyn Ogwen. For an epic Grade 1 outing, scramble up the rocky turrets of Bristly Ridge before descending the similarly awesome Y Gribin arête.

Skirrid Fawr summit

Highlight • Climb

Skirrid Fawr is an iconic little mountain on the edge of the Brecon Beacons National Park. Just across the valley from the Sugar Loaf and the Blorenge. All in all they make a classic local Three Peaks challenge. Don't be fooled by Skirrid's small stature, it will give you a good stiff climb from any direction.

Poised and elegant, Fan Brycheiniog is the climax of a striking escarpment edge in the Black Mountain range of the western Brecon Beacons. From sculpted valleys to pretty tarns, the gently-curved, grassy escarpment – the Carmarthen Fan – provides lovely ridge walking. Nearby Llyn y Fan Fach is famed for the Lady of the Lake legend.

Expect tricky terrain. It's very rocky and uneven with hidden holes.

The Castle of the Winds is a true highlight on this or any other mountain. Spectacular and spiky it makes for a great scramble over the top!

Easy accent if climbing from the side of the national trust carpark. For a more challenging climb, accend from the opposite side.

The name "Snowdon" is first recorded in 1095 as Snawdune, and is derived from the Old English elements snaw and dun, meaning "hill of snow". The Welsh name for the mountain, Yr Wyddfa, is first recorded in Latin as Weddua vaur in 1284. This is probably an approximation of Pen y Wyddfa Fawr. The element gwyddfa in this context means "height, promontory", and also occurs in the Welsh name for the town of Mold, Yr Wyddgrug. Gwyddfa later developed the meaning "gravestone heap", and there is a legend that the giant Rhita is buried beneath the cairn on the summit of the mountain. According to one legend, the giant Rhita was slain and buried on the mountain by King Arthur, while another legend suggests that Rhita was killed by the giant Idris who lived on the mountain Cadair Idris. The mountain is also associated with other figures from Arthurian legend, a legendary Afanc (water monster) and the Tylwyth Teg (fairies). (Wikipedia)

March 19, 2024, Pen y Fan

The highest peak in south wales and still a very easy one to reach with a short walk up the too straight and too perfect path from the parking. The view is well worth it and if you choose an exotic time or less good weather it is even relatively quiet up here. National Trust put a sign on top of th cairn which is the standard selfie spot here now - gives a bit mixed feelings as the cairn is an ancient burial site.
