Full-Day Private Cruise of Khai and Mai Ton Islands

5 Star Marine’s private cruise to the Khai Islands and Mai Ton runs at a flat $805 for the boat — up to 15 people — rather than a per-person rate, a different pricing shape from group day trips covering the same waters. The 5-8 hour route is fixed rather than custom: after check-in at the operator’s office and a briefing over coffee or tea, the boat calls at Khai Nai for shallow, family-friendly snorkeling, then Khai Nok for a beach break, a third Khai island (listed as Khai Nau in the operator’s own itinerary), Mai Ton — nicknamed Honeymoon Island — and finally Koh Rang Yai.

Lunch is not included in the $805 price, despite the itinerary description mentioning a chance to eat at Khai Nok — food and drinks there are bought separately, alongside bottled water, soda, snacks and snorkel gear, which are covered. Dolphin sightings near Mai Ton are described as possible rather than guaranteed. The 5.0 rating comes from only 27 reviews, a small sample next to the busier group tours out of Phuket, so the perfect score is worth treating with some caution.

Prams, strollers and specialized infant seats are available on request, and service animals are permitted, which makes this one of the more accommodating private options on the water. Koh Rang Yai, the final stop, has a public beach with fresh fruit and drinks and a sunset option if timing allows. For a longer, custom-route alternative from the same operator, 5 Star Marine’s Phang Nga Bay charter runs 6-8 hours from $1,045 and lets guests set the day’s stops themselves.

Watch out: Lunch isn’t included despite the itinerary mentioning a meal stop at Khai Nok — budget separately for food there.

Insider Tip: Because the $805 is a flat rate for the boat rather than per person, filling the group closer to the 15-person cap brings the per-person cost down toward standard group-tour pricing while keeping the charter private.
