There are actually several volcanoes in Spain, but the most famous and active one is Mount Teide in the Canary Islands.

Here are a few others:

* Cumbre Vieja (also in the Canary Islands), which erupted in 2021.

* El Hierro (another Canary Island) which had a series of underwater eruptions in 2011.

* The Calatrava Volcanic Field in central Spain, which has several dormant volcanoes.

* The Campo de Calatrava in the region of Castile-La Mancha, which boasts over 300 volcanic cones.

While most of these volcanoes are currently dormant, they are a reminder of Spain's volcanic past.
