Many people think of Brittany exclusively for its coasts. That is a mistake, because parts of the interior are just as rewarding. Huelgoat is a delightful village on the edge of a lake, surrounded by one of Brittany's last remaining ancient forests.
The real draw is the extraordinary chaos of granite boulders in the forest, some the size of houses, piled together in dramatic formations along a river gorge. Walking trails wind past the Roche Tremblante (a 137-tonne boulder you can actually rock by pushing in the right spot), the Grotte du Diable, and the Mare aux Fées. Further into the forest, the paths lead to the Camp d'Artus, an Iron Age hillfort with ramparts still visible in the trees. It is a place where Arthurian legend feels plausible.
Huelgoat makes an excellent base for exploring inland Brittany — the Monts d'Arrée, the moorlands of the Parc Naturel Régional d'Armorique, and the quieter villages of Finistère are all within easy reach.
