La Garrotxa is in the north of Catalonia, at the high basin of the river Fluvià, the Muga estuary and the Amer and Llémena river beds
In this county you can see two totally different types of countryside. In a large part of the southern half there are more than 40 volcanoes and various lava flows, forming a gentle countryside without dramatic gradients, which is protected by La Garrotxa Volcanic Zone Natural Park.
The vegetation reflects the climate. While in the Alta Garrotxa and the east of the county there is an area of typically Mediterranean vegetation, the rest of the county is covered with sub-mediterranean vegetation that becomes Atlantic in the most humid parts.
Holm oaks are typical on the sunny hillsides of the eastern sector, with relatively dry and hot summers, the oak tree predominates in other parts, and the beech is found in the most humid sectors. On the Olot plain, the most characteristic natural species is the common oak, although nowadays its presence is limited to small woods found around the city.
