AO THIAN OG

34 miles from Ao Nathon, Koh Samui

AO THIAN OG. 10°3.674N, 99°49.960E

Both of these bays offer protection in the northeast season. As everywhere around Koh Tao, use the moorings; don’t anchor anywhere near coral. There are restaurants and bungalows ashore, with good access at high tide only.

In the southwest monsoon, shelter can be found just to the north in Ao Leuk. Artificial reef has been laid in Ao Leuk so don’t anchor here. Orange moorings are available.

Pandemic impact

The current edition was published just a few months before the Covid-19 pandemic started to bite. We have not attempted to update this online version (or the new ebook version) as some situations change rapidly, while others are subject to unverifiable rumour.

So, if you are cruising now, please verify information before setting out for your destination and please understand that amenities ashore may be less than posted here or in the book. As 'compensation', you'll find many islands and beaches in the kind of pristine condition not seen for many years in the more developed tourist destinations.
