Two dive centres on Koh Mak run trips to the Koh Rang reefs and nearby pinnacles. They also fill tanks and sell dives to visiting crews.
Practical
The Lost Passport puts Koh Mak Divers and BB Divers just back from Ao Kao beach. OpenStreetMap maps Koh Mak Divers at 11.8112N 102.4767E (used here) and a BB Divers point at 11.8250N 102.4705E near Ao Suan Yai. Iamkohchang says BB Divers also has offices on Koh Chang (White Sands and Bang Bao) and Koh Kood; its 2025–26 two-dive fun-dive trip was 3,500 THB. Ask about tank fills for your own gear.
