Parc Natural de la Zona Volcànica de la Garrotxa

6 Best Day Trips from Barcelona, and the Itinerary to Know for Each | Condé Nast Traveler

"An hour’s drive northwest of Girona will present a word you never thought you’d see in mainland Spain: volcanoes. Garrotxa Volcanic Zone Natural Park actually has 40 of them (no longer active, you’ll be relieved to hear). Volcà del Croscat, the last to erupt, did so (a rather reassuring) 11,000 years ago. The area is still considered seismically active though, with earthquakes in the early 1900s. Scary stuff aside, it makes for a spectacular national park: the ground bursts into giant forested domes and misty valleys, while tiny villages perch perilously on cliff edges. For hikers and cyclists, it’s a dream." - Gemma Askham,Jessica Benavides Canepa
