San Sebastián – Isla de Santa Clara – Basque Country (Euskadi)
Site Overview
The Isla de Santa Clara sits in the Bay of San Sebastián, its shallow reef a gentle, clear-water site ideal for training and macro diving. Cuttlefish, octopus and wrasse fill the rocky ledges, and the easy boat access from the city makes it a convenient introduction to Basque diving. Beginners explore the slope at 3-16 m while photographers hunt the small critters, and the famous old town above adds culinary reward. Santa Clara is a relaxed San Sebastián favourite. 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.
