The river continues in a northeast direction to join the Tavignano in the town of Corte.

The Restonica Valley is an important source of tourist income for central Corsica and has been a listed site since 1966.

Tourists may visit to contemplate the scenery, to swim in its clear waters, or to access the high mountains via the GR20 trails.

The course of the river is dotted with waterfalls and deep natural basins carved into the granite that visitors can use to cool off during the heat of summer.

It is the deepest lake in Corsica with a maximum depth of 42 metres (138 ft) and stays frozen for more than eight months each year.
