Manta Dive is one of the longest-standing dive resorts on Gili Trawangan, established in 1999 and now an SSI Diamond Instructor Training Center. Known for high standards and a relaxed, social vibe, it pairs diving with on-site accommodation, a bar and restaurant, and training from Try Scuba to instructor level, including tech diving.

Daily boats cover the Gilis' turtle-rich sites, from Shark Point and Simons Reef to the Bounty Wreck. Staff teach in English, German, French, Spanish and Indonesian. With around 1,300 Google reviews at 4.8, it is one of the islands' most-reviewed operators.
