El Festival de Senderisme Vall Fosca Pirineus is a hiking festival that invites participants to discover new parts of the valley through activities that bring them closer to geology, natura and regional history. Unique events include the “witch hunt,” walking tours with local guides and tasting menus featuring local products. Participants are advised to wear weather-appropriate attire and hiking boots, as well as bring a rucksack, water and sun protection for all outdoor events.
