Samui Boat Charter, Private Speedboat Charter, Angthong National Marine Park

Angthong National Marine Park’s 42 limestone islands lie about 30 nautical miles from Koh Samui and get congested in peak season with shared tours. This private speedboat charter caps your group at 14 and runs an eight-hour itinerary through the park at your own pace, with hotel pickup on Koh Samui included. At $1,576, it’s a charter price built for families or small groups.

After hotel pickup on Koh Samui, the crew transfers you to the speedboat for the run across to Angthong. The highlight is the Emerald Lake viewpoint on Koh Mae Ko, a hidden saltwater lagoon reached via a steep staircase climb with views across the archipelago’s limestone stacks and jungle. Snorkelling stops work around the park’s coral sites, with gear provided and the crew choosing sites based on conditions on the day. A freshly cooked Thai lunch is served on board. The private format means you can spend longer at whichever island you like rather than watching the clock.

Pack reef-safe sunscreen, a hat, and a light rash vest for snorkelling. The viewpoint climb involves roughly 400 steps so skip it if you have knee or mobility issues. National park entrance fees aren’t included (around 300 THB per adult) and lunch and kayaking are noted as exclusions in the listing, clarify on booking. Angthong closes to visitors during monsoon season (typically November), so check dates before booking. Hotel pickup and drop-off, professional guide, bottled water, snorkelling gear and beverages are included. Lunch, kayaking and the park entrance fee are excluded, so factor those in when calculating total cost. A 4.9 rating across 53 reviews is consistent with the premium format and small group cap. Bring a waterproof phone pouch for the Emerald Lake climb.
