Located at Perhentian Besar (Big Island), this spot is only accessible by boat. Most tour operators would include Tanjung Basi along with Teluk Pauh, Pulau Rawa and Tokong Burung in snorkeling day-trips.
The distance from Teluk Pauh to Tanjung Basi is about 10 minutes by boat.
If you think feeding a few fish is easy, try a few hundreds of them! This is what I found about Tanjung Basi. The fish is extremely friendly and will gobble anything you feed them.
The water is quite deep and there is no beach here, just rocky shorelines. The type of fish are the regular tropical ones such as Indo-Pacific sergeant (Abudefduf vaigensis), scissortail sergeant (Abudefduf sexfasciatus), moon wrasse (Thalassoma lunare), dark-capped parrotfish (Scarus oviceps), red-breasted Maori wrasse, etc.
Occasionally a turtle would appear down deep at the bottom, grazing for food. During my time here, I saw one hawksbill turtle deep at the bottom floor. Turtles are quite a rare sight though, one could be guaranteed to see more turtles at Teluk Pauh.
During this snorkeling trip, I also spotted a black-tip shark about 1.5-meter length lurking in the distance! Nonetheless, the encounter was too brief to be captured on my camera.
