Koh Waen Train Wreck
Koh Waen is a small island in the Trang group, just north of Koh Kradan, offered by Koh Lanta centres as a two-dive day. Its artificial reef includes a sunken train – railway cars and a locomotive – placed on the seabed, alongside natural reef with diverse hard coral and 'Swiss-cheese' swim-throughs. Published depths range from about 5 to 30 m.
