Scattered around the Beddgelert Forest is a veritable treasure trove of dolerite boulders. The best spots are quite spread out; consequently some visitors choose to speed the approach up by cycling in on mountain bikes. This is quite strenuous on the way up, but does mean you can enjoy a 5 minute glide back down the forest trails at the end of the day. Most landings are fairly good, but they are normally a bit damp so a pad is essential.
Most of the boulders are sheltered from the wind – this makes them a good option on really blowy days but it also means they are slow to dry (and prone to midges during the summer). Two days of dry weather will give you a good chance of finding dry rock - this rule is especially important in the winter when the rock will be even slower to dry.
The usual approach is from the Rhyd Ddu end of the forest. Cross the railway by the pull in spot and follow the track running straight into the forest. Take the second right turning, and then bear right at the next junction. After a few hundred metres the track bends left and runs up hill. A prominent boulder is seen on the right - this is adjacent to the Boss Cuvier block (arguably the best boulder in the forest). See the guidebook for the best access routes to other boulders.
