Bas valley

In the southwest of La Garrotxa lies another valley that gives its name to a municipality in which it lies. Also including the town of Les Preses, this valley was formed 11,000 years ago when the lava flow from the volcano Croscat dammed the river Fluvià around Els Tossols (Olot) and created behind it a large barrage lake.

This is the largest and most fertile valley in La Garrotxa and is home to picture-postcard villages such as Hostalets d'en Bas, Joanetes and El Mallol. It is also much loved by touring cyclists who appreciate its flat landscapes.
