About this site
One Tree Bay is a small protected bay on the north side of the main island at Tioman. It gives a sheltered place to dive when the south wind is blowing, and the dive works at every level, down to a maximum depth of 20 metres.
With moderate current the reef fish are plentiful. When the current runs strongly, it pays to keep an eye on the open water, because larger animals can cruise past unexpectedly.
