The snorkeling spot is located on Teluk Dalam beach itself, which is in front of Berjaya Redang Beach Resort. Nonetheless, you will need to swim out toward the left side for about 100 metres before you can start to see some corals and fish.
In general, the snorkeling was quite tiring. Perhaps this snorkeling spot is best accessed by boat, not by swimming. Anyway, it seems that this is the only snorkeling spot directly from the resort.
After a while, I started to see a variety of hard corals such as brain corals, Porites sp. corals with a number of colourful christmas tree worms, green staghorn corals, table corals (Acropora sp.), etc. Overall, it was as prolific due to the water depth and the general condition of reef itself.
Also, there weren't particular many types of fish to see here. The common ones should include the ubiquitous sergeant fish, silvery pompano, parrotfish, brown-bar damselfish, etc.
