Dinas Emrys

The tale says that King Vortigern's castle walls kept collapsing until the young Merlin revealed two dragons beneath the hill. The red dragon defeated the white one, and Dinas Emrys became part of the story behind Wales's national symbol. That is legend, but the hill has real archaeology: an excavation found a lake and a repeatedly rebuilt fortress linked to the period associated with Vortigern.

Start at the Craflwyn car park, about a mile outside Beddgelert, and follow the marked route to the summit. The out-and-back walk is about 2.2 miles (3.5 km) and usually takes 1½ to 2½ hours. It is mostly a gentle uphill walk, but the final approach becomes steep and rocky, with uneven ground, steps, and stiles along the way. One rocky section is particularly awkward when wet, and muddy patches are common after rain.

Dogs are welcome on leads. Toilets and the practical parking are at the Craflwyn starting point, not on the hilltop, so carry water and a snack before setting off. Wear footwear with good grip and leave extra time if the weather is unsettled.
