Big Stone
Why dive here
Big Stone is a pinnacle dive where divers can encounter dolphins, humpback whales, oceanic whitetip sharks, sea turtles and spinner dolphins. Water ranges 23-31°C, warmest July, August, September.
Big Stone sits off Marsa Alam’s coast, a good bet for divers hoping to spot some larger pelagics. While the reef itself isn’t a showstopper, the real draw here is the potential for encounters with false killer whales and long-beaked dolphins, which occasionally pass through. It’s a site we’d recommend for experienced divers keen on covering ground and keeping an eye on the blue, rather than those focused on macro life.
