Banco Dollabarat is an offshore seamount dive in the Formigas/Dollabarat marine-reserve area of the Azores. It is a boat day built around open-ocean current, blue-water pelagics, and a shallow seamount top that quickly falls away into deeper water. Divers come here for large groupers, tuna, wahoo, and the chance of manta rays or sharks, with cetaceans and seabirds often part of the ride out. It is not a beginner site; the long approach, current, and offshore exposure reward experienced divers who are comfortable planning around changing conditions.
