Why this half-day
It's the most magical outing of the day on a mini budget. You set off in early afternoon, enjoy the snorkeling sites once the morning tours have left, and string together two rare moments: sunset out at sea, then a swim in the bioluminescent plankton after dark.
What you'll experience
The long-tail takes you away from the noise for the sunset, engine off, facing the horizon. Once night falls, your guide finds a sheltered spot where the water glows at the slightest movement: a natural effect produced by the plankton, strongest on moonless nights.
Good to know
The intensity of the plankton depends on the moon and the weather — it's a natural phenomenon, never 100% guaranteed, but your guide stacks the odds in your favour. Bring something warm for the trip back; it cools down once the sun has set.

Before you go
Good to know
Prone to seasickness?
Take a tablet ~30 min before departure, sit mid-boat, keep your eyes on the horizon and avoid heading out on an empty stomach.
Beat the crowds
Iconic spots like Maya Bay are far calmer early in the day. Our morning departures get you there before the midday ferry rush.
National park fees
Some sites sit inside a national park, so an entrance fee may apply. Check the “Not included” list above so there are no surprises.
Sun & reef care
The tropical sun is strong — bring a hat, sunglasses and plenty of water. Reef-safe sunscreen is required in Thai marine parks.
What to pack
Swimwear under your clothes, a towel, a dry bag for your phone, and a change of clothes for the trip back.
