Day trips from Chalong, liveaboards from Khao Lak, courses for first-timers. Prices are live at Divebooker and PADI Travel — we earn a small commission, you pay the same, and you get free cancellation on most.
Four days, fourteen dives, one route north from the Similans to Richelieu Rock. The single best diving week you can buy in Thailand.
Out at 8, back by 4. Two or three dives, lunch on deck.
The classic Phuket day: two dives, a hot lunch on deck, and a nap on the sun deck back to Chalong.
Three dives around the Bida islands — walls, sharks, turtles — with lunch under the cliffs of Phi Phi Leh.
Phuket's greatest hits in one boat: the ferry wreck, the leopard-shark pinnacles, and the anemone pinnacle. Big day, big smiles.
Sunset from the deck, then torches on. Cuttlefish hunting, morays free-swimming, and bioluminescence when you cover your light.
Three dives in the clearest water in Thailand, including the Cathedral cavern. Best combined with a couple of nights on Lanta.
Eat, sleep, dive, repeat. The only way to reach the Similans and Richelieu Rock properly.
Short on time, long on ambition. Koh Bon, Koh Tachai and Richelieu Rock in two days out of Khao Lak.
The route south: manta pinnacles, the Cathedral cavern, and Phi Phi walls. Runs when the Similans are closed, too.
From first breath to certified in three days of warm water.
Never dived? Racha Yai's sandy shallows are the gentlest first breath underwater on the coast. Two dives, one instructor, zero pressure.
Get certified in the warmest classroom on earth. Theory online before you fly, then three days at sea.
