Calypso Scuba Diving is based at Camp Almissa (ex. Galeb) in Omis, Croatia, running SSI-standard courses and daily boat excursions to Brac, Hvar, Solta and other spots along the coastline for wreck, reef, cave and night diving. First-time divers can try Discovery Diving (single or double-tank, no licence required, to about 5-8 m depth with full briefing and equipment), while certified divers progress through Open Water, Advanced Open Water, specialty and Search & Rescue courses. The center also runs multi-day diving safaris aboard the 12 m boat "Sal" with a two-person crew, visiting numerous caverns, reefs and shipwrecks along the Croatian coast, and sells and rents diving equipment.
