Huelgoat is popular with tourists and holidaymakers due to its impressive natural setting among the vestiges of the ancient forest that once covered inland Brittany.
A number of geological and prehistoric curiosities can be found by following trails in and around the village and forest. Among these are:
- Le Chaos de Rochers, the Chaos of Rocks, is a jumble of hundreds of large boulders below the dammed lake, into which the river vanishes. A 10 m descent down ladders is required to see it again, running rapidly below a dark cave called the Devil's Grotto.
- La Roche Tremblante or Trembling Rock, is a 137-tonne boulder nearby, pivoted so it can be made to rock by a person pushing against one point.
- Le Champignon, orThe Mushroom, is a large rock balanced on a smaller one to give the eponymous appearance.
- La Mare aux Fées, The Fairies' Pool.
- La Mare aux Sangliers, The Wild Boar Pool.
- Le Camp d'Artus, Arthur's Camp, a sea promontory hillfort based on a Gaulish oppidum, with a linear murus gallicus rampart. It was used as refuge by the Osisme Gauls against the Roman invasion in 57 BC and later acquired a nickname referring to Arthurian legend. The site was excavated by Sir Mortimer Wheeler.
- La Grotte d'Artus, or Arthur's Cave, is a natural shelter formed under a roof of jammed rocks
