One of the best diving sites at Komodo National Park, Crystal Rock is a sea mound covered with some very nice soft coral. A thriving and healthy marine life here is excellent featuring whitetips and blacktips sharks with grey reef sharks if you venture deeper. You will also find schools of batfishes alongside many giant trevallies and dogtooth tuna.
Though the water here is very clear, be careful as the current here can be very strong at times.
This location in fact is a reef and an excellent place for diving and spotting sharks. Moreover you can easily access from the shore, and can also come here any time of the year.
