Poco Naufragio (Wreck), Amarilla is a boat-access wreck dive beside Marina San Miguel in Tenerife, where a short swim leads to a small wooden wreck set in a lively coastal canyon. Resident stingrays and schools of fish are the main attraction, so the dive feels active and social rather than coral-heavy. Plan for relaxed guided buoyancy, stay aware around the rays, and treat the wreck as a compact feature wrapped in open-water fish life.
