Costa Tropical rewards divers with a varied mix of wrecks, walls, reefs, caves and drift sites, most of them concentrated around Almunecar. The marine life leans heavily towards cephalopods and elasmobranchs, with the Common Octopus, European Common Cuttlefish and Marbled Electric Ray observed across nearly every site. Ocean Sunfish and Flying Gurnard add pelagic interest, while the reef hosts a remarkable diversity of nudibranchs. Most sites suit beginners, with a handful of deeper walls and pinnacles reserved for intermediate and advanced divers.
