Dolbadarn Castle controlled an important route into the heartland of medieval Gwynedd and was close to rich cattle pastures that provided food and income. Begun in the 1220s, the castle was built in ten years. The round tower consisted of two floors with comfortable accommodation over a basement and was a princely castle... The builder Llywelyn ab Lorwerth died in 1240, and despite his efforts to secure a peaceful succession in Gwynedd, a struggle began that did not find a clear winner until 1255. Llywelyn's grandson, Llywelyn ap Gruffudd, defeated his brothers in battle and became Prince of Gwynedd. But they still posed a threat, and Llywelyn held Owain Goch, his eldest brother, prisoner in Dolbadarn. Here he was held captive for twenty-two long years. The 13th-century poet Hywel Foel ap Griffri described Owain as "a man in the tower, long a guest."

A beautiful, large Castle with many towers you can gogo up to have a great view of the surrounding area. A very rewarding destination for any tour. if you go in, plan at least 1-2 hours to go everywhere, or just admire the walls from outside.

The Miners' Track is one of two paths beginning at Pen y Pass. The track will take you along the shores of Llyn Teyrn, Llyn Llydaw and Llyn Glaslyn before ascending steeply to meet with the firstly the PYG track then both miners and PYG continue to ascend to meet with the Llanberis Path to Yr Wyddfa's actual summit. Miners' Track was built to serve the Britannia Copper Mine. However, the track wasn't the route used to serve the mine initially. Before the route's existence, miners lugged copper up the eastern slopes of Yr Wyddfa (Snowdon) to be drawn by horse and sledge down to Llyn Cwellyn.
