Islas Columbretes – Valencian Community – Costa Blanca & Columbretes

Site Overview

The Islas Columbretes are an isolated volcanic archipelago off Castellón, a pristine marine reserve whose walls hold large dusky groupers, amberjack, tuna and eagle rays in remarkably clear water. Reached only by long day-boat or liveaboard from Castellón, the islands offer some of the healthiest reef in the western Mediterranean. Advanced divers explore the drop-offs and pinnacles, while the remoteness keeps the experience exclusive. Columbretes is a bucket-list destination for Spanish divers. The site rewards careful planning, good buoyancy and respect for Spain’s marine-protection rules, and remains a favourite among divers who value dramatic volcanic or Mediterranean scenery, historic wrecks and rich marine life across a long, varied season.
