The day heads far south-east: first snorkelling at Koh Rok (Siam Bay or Rok Nai), midday on the white beach, then the limestone finale around the Koh Haa group. The park has clear rules: don’t touch the coral, use reef-safe sunscreen, and wear a life jacket if you’re unsure in the water.
Koh Lanta is the neighbouring island where you sleep – not the destination of this tour. Maya Bay only? Book Phi Phi. The clearest water north of Phuket? That’s Similan in season. Rok and Haa are the long south.
Calmer sea, clear water – the day worth getting up early for. December to March: book ahead.
Swell from the south; many dates are cancelled or moved. This is not a Coral day you “do anyway”.
Pickups often start before 07:00. If you get seasick easily, take the tablets beforehand – not in the first swell. Stay off the coral. Dolphins at Maiton are luck, not a show. The crossing is long, so the tour suits school-age kids and up; with toddlers, Coral is the better introduction.
A day tour that returns to Phuket the same evening. The ferry to stay overnight on Koh Lanta has its own page.
Different direction, different park. Similan lies north and closes from mid-May to mid-October. Rok and Haa lie south-east; the long tour from Phuket is mainly worth it from November to April.
From ฿3,499 per adult; children aged 4–11 often join for ฿2,999, and under-4s are usually free. Transfer and park fee are typically included.
No. On this tour Haa is the second snorkel stop of the same day – not its own trip.
Life jackets yes, shallow spots at Rok yes. But the crossing is longer and rougher than Coral. Under six: choose Coral or Koh Khai instead.
