One Tree rock is exactly what it says on the tin, although now a second tree has grown. The dive site is a circular reef with large tables of hard coral. These make excellent hiding places for Moray eels, blue spotted Fantail String Rays and large common puffer fish. If you’re lucky you might spot a turtle here in July. The further from the island - the deeper you go. Toward the north side of the island are some large bolders with soft coral. To the west there is a large rock reef heading away from the island with some larger soft coral.
