Tossa de Mar is a little over an hour drive north of Barcelona. In the 12th century the medieval town was walled off and a castle was built on the highest point of Mt. Guardí.
The town was popular with Spanish and foreign artists during the 1930’s and the municipal museum has a good collection including the Celestial Violinist by Marc Chagall.
There is a trail with great views that goes between Tossa de Mar and Lloret de Mar. The route between Tossa de Mar and Lloret de Mar coincides with section 11 of the GR 92 trail.
