Qeshm Island sits in the Strait of Hormuz in the Persian Gulf and is Iran's largest island, recognised as a UNESCO Global Geopark with parts of its coastal environment formally protected. Diving here spans reef and wreck sites ranging from very shallow water to around thirty metres, suiting all skill levels from beginner to advanced. The water is warm year-round, rising to its peak in summer and cooling slightly in the cooler months that many visitors prefer. Expect to encounter green and Ridley turtles, scalloped hammerhead sharks, nurse sharks, lionfish, nudibranchs, and octopus across both reef and wreck terrain.
