The translucent waters of Oman invite glimpses of kaleidoscopic coral gardens. A vision of colour, sunken ships and sanctuaries for exotic shoals of fish. With 1700km of pristine coastline shaded in sapphire blue, Oman is a snorkeller’s paradise. Sink down into rich mangrove coves, paddle alongside loggerhead turtles, and marvel at dolphins, humpbacks, and leopard sharks that populate the rich waters of the Hallaniyat Islands.
