The small coral reef facing the Tuna Bay Island Resort is one of the good snorkeling spots on the west coast of Perhentian Besar. Protected by buoys and well-sheltered, it allows you to snorkel in good safety. conditions. The reef, partly natural and partly artificial, is quite damaged. We still see a lot of fish there, such as clownfish, bumphead parrotfish and blue-ringed angelfish.

How to get to Tuna Bay snorkeling spot?

This site is located in the Perhentian Islands, along the west coast of Perhentian Besar, right in front of the Tuna Bay Island Resort. This area can be reached on foot via small paths through the jungle from Teluk Pauh (to the north, where the Perhentian Island Resort is located) or from Flora Bay (to the south).

If you stay at Tuna Bay Island Resort, Abdul Chalet, Beach Box Perhentian or Suhaila Palace, you will be right next to the spot. The snorkeling zone corresponds to the swimming area delimited by white buoys.

Water entrance for snorkeling Tuna Bay

Water entrance is very easy, from the sandy beach. The spot is marked by buoy lines which prevent boats that dock on neighboring pontoons from entering the reef area.

Tuna Bay snorkeling exploration tips

The main snorkeling area corresponds to the swimming area delimited by lines of buoys. It is recommended not to leave this area due to the important boat traffic near the shore.

Tuna Bay features natural coral reefs as well as artificial reefs (metal structures partly colonized by corals) in the deepest parts. At low tide, it is difficult to snorkel in the center of the bay because the corals are outcropping on the surface of the water, but it is still possible to snorkel around the reef.

Tuna Bay corals are overall very damaged. Even if some patches of branching corals, Porites and digitate corals are still healthy, you will also find large areas of dead coral debris.

The reef areas host many sea anemones in which clownfish live. At least three different species can be observed on this spot: the Ocellaris anemonefish, the Clark’s clownfish, and the Tomato clownfish (see list of species at the bottom of the page).

Additional fish species that are easy to see in Tuna Bay include the beautiful blue-ring angelfish, rabbitfish, butterflyfish, and schools of large humphead parrotfish grazing on the coral.

You can also explore the Marine Park jetty, at the western edge of the spot (see map). Schools of thousands of fusiliers shelter in the shade of the platform and around the pillars, where silver moony and sergeant majors also abound. Stay away from the end of the jetty, which is not protected by buoys.

Visibility in the swimming area is quite good, and the sea is calm, except when a speed boat passes nearby.
