Phoenix Divers

Phoenix Divers has been teaching people to blow their first bubbles on Koh Tao since the early ’90s, and they still keep it friendly and low‑key. Their beachfront shop backs straight onto Sairee Beach, so you’re never far from the boat or a sunset beer after your dive. Expect small groups, SSI courses taught with patience, and a crew who clearly love the island and the water. First‑timers start with a calm session in the training pool before heading out to Koh Tao’s easier sites for turtles, anemone gardens, and the odd school of barracuda. Already certified? Sign on for fun dives or level up to Advanced and specialties; Phoenix runs morning and afternoon boats most days when conditions allow. Packages often include simple rooms near Sairee, which keeps costs down and the commute to zero. It’s an easy place to hang around even if you’re not diving that day — sandy feet, salty hair, and a steady flow of backpackers swapping dive stories. Drop by the shop at 1 Moo 1, Haad Sairee (Koh Tao 84360) or message ahead to line up your course. They’re typically open daily from 9am–8:30pm; call +66 77 456 033 or check phoenixdiverskohtao.com for updates and availability.
