At the base of the Llanberis pass sits Dolbadarn Castle, or at least what is left of it, another 13th century fortification in the North of Wales. This one is a little different in that it was an important port of Llywelyn the Great’s power, and its stone keep has been described as the finest remaining example of a Welsh round tower that exists. All this is well and good, but we’re most excited about the views you get from this part of the world; it isn’t hard to see why the castle was built here. You won’t get a better picture of Llyn Padarn than from this vantage point.
