If you want an good half day walking then this is the walk for you. This walk takes in two summits, Gallt yr Ogof and Y Foel Goch and the amazing Braich y Ddeugwm ridge – the panoramic’s are simply magnificent. Wear sturdy boots, take warm clothes and waterproofs and some snacks. Use OS Explorer map OL17. The walk is approximately 5 miles and will take about 3 hours of moderate walking.
Park at Gwern Gof Isaf farm (Sat Nav LL24 0EU). Follow the main track through the campsite and cross the Nant yr Ogof stream into open country. Walk a few yards along the track then cross a drainage channel and beginning the slow steady ascent of Gallt yr Ogof. The route is vague so head diagonally left wards whilst walking uphill, through bogs and over boulders until you meet a fence heading across the mountain. follow the fence upwards and cross it at the first stile you come to and follow it up onto the ridge.
The views upon gaining the ridge are lovely and offer a pleasant reward for the effort involved in getting here. Follow the ridge along until you reach the top of the mountain at 763m/2503ft.
These views are fantastic and vast. The impressive peak beyond Capel Curig is Moel Siabod.
Y Foel Goch is the next summit, reached by a descent to a boggy col with a small babbling brook. Ascend the mountain up a wide ridge onto the flat summit with a cairn at 805m/2642ft. Again some great views over the Snowdonia massive.
The descent route goes down to the pools of Llyn Caseg-Fraith, then goes north off piste to the spot height Drws Nodded to locate the top of the Braich y Ddeugwm ridge.
From Drws Nodded the ridge is fairly clear and it is an easy and steady descent with a few scrambles in places. Ignore the paths running down the right hand side, it’s very wet and misses a lot of the views which make this ridge so good, keep to the crest instead and follow it all the way back down to Gwern Gof Isaf.
The ridge breaks a few times but the main crest is pretty obvious to follow and at the end of the ridge go over a ladder stile and down some steps to the farmhouse, the car being a short walk down the track to the road.
This is a beautiful, if little done walk that offers some of the most magnificent views of the Snowdonia national park.
