The walk
The walk makes a circuit from the car park at Ogwen. It goes up to the north shore of Llyn Idwal and climbs the north-east ridge of Y Garn (946 m), the armchair-shaped peak above the lake. From the summit it drops to Llyn y Cwn and comes down the Devil's Kitchen path under the cliffs of Twll Du, back into Cwm Idwal, a classic glacial cirque studied by Darwin. It is on path nearly all the way.
It is 7.7 km with 721 m of ascent; allow about 5 hours. The grade is Moderate for a fairly short day, but the north-east ridge is a steep, sustained climb and the Devil's Kitchen path is steep and rocky on the way down.
The ground around Llyn y Cwn needs care in mist, so carry a map and compass, check the mountain forecast and be ready to turn back. In winter the Devil's Kitchen holds snow and ice and needs an ice axe, crampons and experience.
The car park charges a fee. Roman Bridge station is about 11 km away in a straight line. There are no mapped water sources on the route.
