Welsh 3000s Challenge
All 15 mountains in Wales over 3,000 feet – Yr Wyddfa, Crib Goch, the Glyderau, Tryfan and the Carneddau – in one superb high-level journey through Snowdonia. Take it on in 24 hours, over a weekend or across three days.
The finest UK mountain challenge, and one of the hardest. Fully guided, with a support vehicle and transport.
“Dave’s our “guide for life”. He’s brought us up and down Mount Toubkal, we have plans for Elbrus, he does local Bristol climbing on the Avon Gorge, Welsh 3000s, trail marathons.”

The Finest Mountain Challenge in Wales
To complete the Welsh 3000s you need to stand on top of all 15 mountains in Wales over 3,000 ft – happily, they’re all clustered around the Snowdonia mountain range. The peaks themselves cover around 26 miles, and the walk in and out takes it to around 31 miles (50 km).
With nearly 4,000 m of height gain – like walking up and down Ben Nevis three times – and several sections of grade 1 scrambling, including the famous Crib Goch ridge and Tryfan, this is a challenge for very fit hill walkers and runners who are comfortable on rough, exposed ground.

Three Ranges, Fifteen Summits
Over two days you’ll do the Snowdon range and the Glyderau on day one and the Carneddau on day two; over three days, one range a day. The route may vary with conditions – see the full route map.
