There is basic tourist facilities on the island, such as sheds and tables for day trippers. Those who wish to overnight on the island can rent the camping tents.
In addition to picnic trips to the island, some operators now offer scuba diving in the vicinity of Pulau Sembilan. Dive sites around the island include White Rock and Black Rock, so called for the colour of the boulders in the vicinity.
