Located at the head of the valley of Assua and at the periphery of National Park, at Llessui’s mountain we find the highest peak of the municipality, the majestic Montsent  of Pallars 2883 m. In their grazing skirts thousands of sheep, cows and horses stay in summer. There are also the remains of the Llessui ski resort closed since the 80s.  From the road along the periphery of the park you can see an exceptional panoramic views.
