There is a long jetty outside of the Paradise Resort that has good snorkeling right off of it. It is possible to swim to the island directly across from Kadidiri, but it takes a few hours. There are sea kayaks for rent from Black Marlin and it takes about 30 minutes to row to a nearby island that has good snorkeling. There are many trails around the island, but some are easy to get lost on. The walks are through dense growths and are not particularly picturesque. Fishing is not allowed in the no take zone so fishing trips must be outside this area. naturally there is diving at Black Marlin more boats and equipment and Paradise, check equipment carefully.
For diving Pulau Una Una The Pinnacle! is the highlight in the area - big groups of Barracudas, Jackfish and Napoleons can be seen. Other good dive sites are The Gap, Dominik Rock, The Crack, Batugilla and for Nightdives especially Little Lembeh.The dive boats take normally also snorkelers for free with them, if the dive site is shallow enough.
