Pulau Paku is a small island off the coast of Pantai Pasir Panjang (Long Beach). It is only accessible by snorkeling boat or perhaps one can rent a kayak from Pantai Pasir Panjang.
Just as you put on your snorkeling mask and put your head underwater, you will be amazed by the expansive garden of green staghorn corals that extends as far as your eye could see.
It goes without saying that the corals here are very healthy due to its considerable distance from Redang's main beaches. I saw a great selection of corals such as sea anemones, brain corals, boulder corals, table corals, etc.
The fish variety is also not bad at all. I saw mostly common damselfish such as Indo-Pacific sergeant, scissortail sergeant, gold-spotted rabbitfish, yellow rabbitfish, moon wrasse, clown anemonefish, silvery pompano, etc.
Overall, this is a great snorkeling spot in Redang.
