Speedboats, classic teak yachts and catamarans — what a private Ang Thong charter costs, who it suits, and when it beats a shared tour. Updated July 2026.
A private boat charter from Koh Samui to Ang Thong Marine Park typically runs 8,000–26,000 THB for the whole boat — and once your group reaches about 6–8 people, the per-person price matches or beats a shared tour while giving you total control of the day: your own departure time, your own pace at the Emerald Lake viewpoint, and no waiting for 30–40 strangers to board.
For couples or small groups of two to four, the maths flips — a private speedboat can cost several times more per head than a shared or semi-private trip. The right call depends almost entirely on group size.
No shared schedule. Linger at the Emerald Lake viewpoint after other boats have left, add a secluded snorkel stop, or time your day around a sunset — the whole itinerary is yours.
Sweet spot vs. shared tours
Typical speedboat charter/boat
From twin-engine speedboats to classic Thai teak yachts and sailing catamarans.
The most popular Ang Thong charter vessel — reaches the park in 40–60 minutes. Typical capacity 4–22 passengers, from ~8,000–26,000 THB per boat.
Slower and more luxurious, with chef-cooked food onboard. Good for groups up to ~24 and special occasions.
Sailing cats for 6–14 guests up to large party catamarans holding 60. A comfortable, stable middle ground.
Motor yachts and superyachts from brokers, weekly rates from ~$24,500 — the top tier for milestone celebrations.
Koh Samui is a springboard for the whole Gulf of Thailand.
Beyond a private yacht charter or private speedboat to Ang Thong Marine Park, from Koh Samui you can also book a dedicated sea-kayaking day tour, a snorkelling trip to Koh Tao and Koh Nang Yuan, an easy family day at Koh Tan and Koh Madsum (Pig Island), or a sunset cruise. Live options are below.
Quoted "private charter" prices range widely by boat size and quality tier — always confirm exclusivity and inclusions in writing before paying.
| Option | Typical price | Capacity |
|---|---|---|
| Shared standard big boat | 1,200–2,000 THB pp | 30–50 |
| Shared/small-group speedboat | 1,800–2,800 THB pp | 8–30 |
| Semi-private VIP speedboat | ~2,500–4,400 THB pp | max 16 |

Some listings labelled "VIP" or "private" actually put dozens of other people on the boat — a documented complaint. Confirm exclusivity in writing before you book.
The 300 THB (foreign adult) / 150 THB (foreign child) national park entrance fee is almost always excluded from the charter price and paid on arrival at Koh Mae Ko, even on private charters.
Three well-reviewed options covering the semi-private, private-speedboat and private-yacht tiers. Check availability above, or compare all three below.
The most-reviewed option here: a smaller, semi-private yacht experience that sits between a big shared boat and a fully private charter — ideal if you want a quieter day without the full private-charter price tag.
A genuinely exclusive speedboat booked per group rather than per person — the pick for couples or small groups who want their own boat, crew and itinerary without a big-boat crowd.
A private day charter aboard a classic Thai yacht for up to six guests — the best fit for honeymoons, anniversaries and other special occasions where comfort and privacy matter more than speed.
Set your own departure time and pace, skip islands that don't interest you, and spend an extra hour at the viewpoint.
Operators time private stops so you hit the Emerald Lake and viewpoint after group boats have left, plus access to quieter sites like Koh Wao.
Honeymoons, proposals, birthdays and weddings are a major private-charter use case — operators can arrange cakes and celebrations en route.
Dedicated crew, help for nervous swimmers and kids, freshly cooked meals, and a day that never feels rushed.
Use a platform with weather-protected free cancellation in shoulder season, so a forecast change doesn't cost you a deposit.
The park closes annually for monsoon restoration — plan around it.
Calmest seas and clearest skies — peak season for private charters, so book several weeks ahead.
Shoulder season — greener, cheaper and less crowded, with occasional rain. Easier to book a private boat last-minute.
Ang Thong National Marine Park is officially closed for monsoon restoration — plan an alternative like Koh Tao or Koh Phangan.
