Neptune Scuba Diving opened in Sanur in 2016 and quickly became one of the area's most popular dive schools. The team teaches PADI courses and speaks English, Indonesian, Mandarin and Romanian, a rare mix that makes the shop welcoming for divers from many countries.

From Sanur the boats reach Bali's best day trips: Crystal Bay and Manta Point at Nusa Penida, the Blue Lagoon at Padang Bai, and the USAT Liberty wreck at Tulamben. Snorkeling trips run alongside fun dives for mixed groups. The school holds a 4.8 rating from its divers.
