El Colector is a boat-accessed temperate reef dive off San Sebastián that runs across a set of east-west slabs beside the old collector structure. It is best approached as a slow, structure-following dive: the site starts shallow and gradually steps down, with crevices, rocky bottom, and plenty of macro life to search for between the slabs. Cold water and variable currents are part of the planning, so buoyancy, exposure protection, and a measured pace matter more than speed.

Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Cold water and variable currents are the main planning factors. A thicker suit and slower search-style dive make the site more comfortable.
Access Restrictions
Boat access from Pasai Donibane is normal, and the site can feel colder or more currenty than its depth alone suggests.
Community notes to help plan your visit.
Scuba Diving
A temperate reef dive with slabs, crevices, and plenty of macro life. Slow, careful passes usually work better than fast finning.
Freediving
Freedivers can work the shallower structure in calm conditions, but the site is mainly better known for scuba.
Snorkeling
Snorkeling is possible over the shallower structure when conditions are calm, though the main habitat sits below the surface.
