Koh Rok and Koh Haa: Snorkelling Day from Koh Lanta
5 min read
The 7.5- to 8.5-hour Koh Rok and Koh Haa speedboat trip with buffet lunch is the best starting point for most snorkellers. It costs €41.67, has 665 reviews and a 4.7 rating. This is a full marine day, not a quick swim from Koh Lanta, and it suits people who actively want several hours built around water.

Why these two island groups are paired
Koh Rok and Koh Haa sit within the wider Mu Ko Lanta marine area and are known for coral and clear-water scenery. The Tourism Authority of Thailand names both among the smaller islands around the national park and identifies Koh Rok and Koh Haa as underwater highlights. Combining them gives the day two different roles: reef time around the islands and a beach or meal break, depending on the chosen itinerary.
Do not book for a particular animal sighting. Fish and coral are the reason to go; wildlife is not scheduled. Visibility also changes with wind, rain and swell. Operators may alter the order or substitute a site when conditions require it.
Who will enjoy the full day
This trip fits confident swimmers, couples and families with older children who already enjoy masks and snorkels. Seven to 8.5 hours can feel long if someone is unsure in open water or dislikes boat transfers. According to the booking page, the minimum age is 4 and pregnant women cannot take part; ask about child-size equipment and whether a non-swimmer can stay comfortably aboard before booking.
For a first snorkelling day, the more-reviewed buffet-lunch tour is the safer comparison anchor. The seven-hour alternative costs €59.80 and has fewer reviews, but may suit a schedule that needs the slightly shorter published duration. Do not choose by boat type: the recommended trip and the third listing both run by speedboat, so the difference lies in price, reviews and timetable.
Season and closures
The Tourism Authority of Thailand says smaller islands around Mu Ko Lanta, including Koh Rok and Koh Haa, are typically closed during the monsoon season from May through October. Treat November to April as the core planning window, while recognising that weather can still cancel a departure. Check the date-specific availability rather than relying on a generic annual promise.
Before booking
Confirm hotel pickup coverage, national-park fees, lunch, mask and fin rental, life jackets and the cancellation rule. If seasickness is a concern, speak to a pharmacist or doctor before the trip; do not wait until the boat is moving. A rash vest and reef-safe sun protection are practical because shade and exposure vary by boat.
Recommendation
Book the 7.5- to 8.5-hour tour for €41.67 if snorkelling is a main reason for visiting Koh Lanta. Pick one of the two seven-hour versions only if a shorter published timetable matters more than the larger number of reviews.
