18 miles from Ao Nathon, Samui
The best anchorage is in 6-8 metres on a sandy bottom in the middle of the bay. Take care to avoid the sand and fringe coral outcrops to the northwest of the bay. The anchorage may become uncomfortable in the southwest season due to ground swell.
Ao Lamai is the second-most-developed bay on the island, with plenty of action ashore. Accommodation of all types is available, together with the usual minimarts, bars, discos and restaurants.
