Walk to the summit of Cadair Idris (2930 feet/893 metres). Parts of the route are very steep, but once on the shoulder of the mountain, the going is easier. There are several routes, but the closest to Dolgellau takes the so-called Pony Path, and takes about two and a half to three hours to reach the summit.
In July, the town plays host to the annual Sesiwn Fawr World Music Festival. With 6 stages, there's something for everyone.
Visit the Quaker Interpretive Centre, within the Tourist Information cente on Eldon Square.
Take a short walk out of town to see the ruins of the 12th Century Cymer Abbey
Tucked away on the idyllic southern shore of the Mawddach estuary, the village of Penmaenpool is only three miles west of Dolgellau. Penmaenpool can be reached by road (A493) or via the disused railway line footpath and cycle route which starts near the main car park in Dolgellau. The railway path "calls" first at Penmaenpool, but extends another three miles or so to Morfa Mawddach and the Barmouth railway bridge which can be crossed for a modest toll.
Continuing westwards from Penmaenpool, the main road turns to the south at Fairbourne. From here it twists and turns along the cliff tops through the pretty village of Llwyngwril to Rhoslefain. Just a few miles to the south lies the town of Tywyn, with miles of sandy beach. Tywyn is also home to the famous Talyllyn Railway.
