82 miles from Patong Bay
This is an all-weather anchorage lying inside an inland waterway protected from the sea by Koh Ra. Entrance from the north is easy, with deep water close to Koh Ra; the southern channel must be navigated with care, especially near the small rock mid-channel, passing to the south of the obstruction. Anchor in 6-10 metres on a muddy bottom just east of the non-navigable channel between Koh Phra Thong and Koh Ra.
About half a mile from the anchorage, look for a village with a jetty that dries at low tide.
