Dolwyddelan can be found on the main A470 road between Blaenau Ffestiniog and Betws y Coed. The village is situated in the picturesque Lledr Valley and is particularly noted for Dolwyddelan Castle, the traditional birthplace of Llywelyn the Great, although it is likely that the castle was actually built later, in the 13th century. Parking for the castle can be found in the Snowdonia National Park car park approximately 500 metres from the castle itself.
In the heart of the village you will find the village shop, Y Gwydyr public house and Elen’s Castle Hotel and Restaurant. The restaurant won the Bwyta Allan (Eating out) award in March 2013 for evidencing that they actively sourced fresh produce locally. There are regular bus and train services in the village, and at the award-winning railway station there is a picnic area set in its own nature reserve.
