Why Malaysia
Around the Perhentian Islands, snorkelling and diving bring turtles, blacktip reef sharks and reef fish. Tioman Island is a protected marine island for freediving-led reef days, with turtles, reef sharks and rays, and occasional mantas and whale sharks. On Tioman the season runs March to October, with May and September warm and less busy.
Conservation-led. Ocean Calling guests never chase, touch or bait animals.
When to go
Timing changes a lot from place to place. See each place below.
We have researched this place and keep learning about it. There is no trip here yet.
Can we travel here ethically?
Ethics pass, with care
Good with the right operator. Here is how we choose.
The Perhentian Islands and Tioman are marine parks where fishing, touching coral, chasing animals and anchoring on reefs are not allowed. Turtles and their eggs are protected by law, and we never buy eggs. So we keep groups small, use moorings, stay off the busy snorkel spots, and never chase or touch turtles or sharks.
Checked 30 Sep 2026. Places change, so we look again every year.
