The two neighbours Bida Nai and Bida Nok are the most southerly
islands of Phi Phi. Because of their various underwater landscapes many
diving clubs come here- even from far awai like Krabi and Phuket. The
boats stop in a small bay and the divers find walls, tunnels, woods of
Gorgones and Soft corals. On the sandy ground between large rocks often
single Leopard-sharks are resting, even if groups of divers are sitting
around or are passing by.
