Columbretes Islands nature reserve
Located in Castellón de la Plana in the Region of Valencia, the Columbretes nature reserve, previously known as the Islands of the Snakes, rises from the Mediterranean Sea as four islands of volcanic origin: Columbrete Grande (AKA Illa Grossa), which is currently the only one of the four that can be visited; La Ferrera; La Horadada (AKA La Foradada); and El Berantín (AKA Carallot).After a scenic boat trip, you will disembark in the port of Tofiño on Illa Grossa, and begin a route that will take you to a spectacular lighthouse some 67 metres tall. This film-worthy location is well worth the trip. As you walk along the path, you'll gradually discover its biological richness and impressive ecology. If you have time afterwards, you can also go snorkelling when you get back to the port. Afterwards, you can observe the seabed at the Castellón planetarium, which has an exhibition about the islands and fishing in the area.
