Toll de l'Olla Waterfall

Highlight • Waterfall

The Toll de l'Olla hides a legend behind it. It is said that it was created by a "farebona" (a good witch).

At the beginning of the 17th century, the residents of the area fell ill and asked him for help. She made a deal with them: she would look for the herbs needed to cure them and they should look for a pot that would hold a liter of water per sick person.

When the neighbors failed, the farebona converted this part of the river into the Toll de l'Olla.

The cave can only be reached from the lower footpath. You have to hike back the same way.
