It's better to do the route by ebike. There's a lot of elevation gain.

The Sant Nicolau river has its origin in the Estany Llong and is fed by the waters of at least twelve lakes during its brief journey until it reaches the Noguera del Tor. Despite its short length, its force is intense, as it crosses one of the most captivating valleys of the Aigüestortes National Park. This valley is surrounded by imposing mountains and forests that have a particular charm.
