You can snorkel around the island and explore the coral reefs around the island if you have your own gear. You can also hire the snorkelling gear on the island. Some interesting spots to snorkel are:
- alongside the walkway leading towards Pulau Tidung Kecil (reef starts just past the bridge)
- outer reef around the island (mostly behind the wave breakers concrete blocks).
You can also book the short snorkelling trip at the water sport shops near the bridge or for better experience you can book a private boat that will take you on remote snorkelling spots.
Please note that there is no detailed map of Tidung island available and there are no street names (not to mention numbers). Each shop can be located by its name if you ask any locals they will point you to the right direction. We are also including the GPS location for each shop/attraction to help you navigate while on island.
