5 miles from Ton Sai Bay, Phi Phi Island
Just west of Ao Lohdalum is a smaller, jungle-fringed, bay with an anchorage outside the seaward edge of the coral in 15 metres.
Yongkasem is an ideal overnight stop at any time of the year and can be used in preference to Ao Lohdalum, for more peace and tranquillity. Both Lohdalum and Yongkasem now have sufficient government moorings so that after 5pm most visiting yachts can stay overnight, even in high season.
At the back of Yongkasem beach, lush foliage provides shade for picnics, and is home to a large tribe of crab-eating macaques. The snorkelling is great. Ao Lohdalum itself also has excellent snorkelling and a wonderful swim-through cave on the west headland. Be hyper-aware when going ashore anywhere on this north side by dinghy that it dries for hundreds of metres at low tide.
