This popular circular walk explores the Nantlle Ridge range of mountains in the Snowdonia National Park.
You'll visit a series of imposing peaks with magnificent views over Snowdonia. The scenery is breathtaking as you make your way along one of the finest ridge walks in Britain.
The walk starts from the village of Rhyd Ddu and heads to the first peak of Y Garn which is only about a mile away. At the 633m (2,077ft) Y Garn summit you will find a rocky plateau, steep cliffs and cairns.
The route continues to the next peak on the ridge - Mynydd Drws-y-Coed. This exposed peak requires a degree of scrambling to reach the 695m (2,280ft) summit.
From here you climb to the second highest peak on the ridge, Trum y Ddysgl. From the 709m (2,326ft) summit you can enjoy wonderful views of Mynydd Mawr,Yr WyddfaandMoel Hebog.
The route then descends to the next peak of Mynydd Tal-y-Mignedd, a subsidiary summit ofTrum y Ddysgl. Here you will find a large stone obelisk, put up to commemorate Queen Victoria's Diamond Jubilee.
Continuing south west you come to the highest point on the Nantlle Ridge, Craig Cwm Silyn. From the 734m (2,408ft) summit there are wonderful 360 panoramic views of the area. The other peaks on the ridge areGarnedd GochMynydd Graig Goch. They are a few miles west of Craig Cwm Silyn and not visited on this walk.
