Colona Divers' Marsa Alam centre is the Swedish-managed Colona group's southern Red Sea base, set at the Deep South Diving Camp on Tondoba Bay. The team focuses on relaxed shore diving plus day trips to Samadai (Dolphin House) and the area's offshore reefs, with PADI training across levels. A laid-back, camp-style operation for divers who want easy reef access and small groups.
