The Economics Tip Toward Private at 6–8 People

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.

Pоwered by GetYourGuide

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.

⛵

What Makes It Special

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.

Other Experiences You Might Enjoy

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.

Prices by Boat Type & Group Size

Quoted "private charter" prices range widely by boat size and quality tier — always confirm exclusivity and inclusions in writing before paying.

⚠️

"Private" vs "VIP" Labelling

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.

🎟

Park Fee Still Applies

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.

Why Book Private Over Shared

🕒

Itinerary Flexibility

Set your own departure time and pace, skip islands that don't interest you, and spend an extra hour at the viewpoint.

🙅

Crowd Avoidance

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.

💍

Special Occasions

Honeymoons, proposals, birthdays and weddings are a major private-charter use case — operators can arrange cakes and celebrations en route.

🍽

Comfort & Service

Dedicated crew, help for nervous swimmers and kids, freshly cooked meals, and a day that never feels rushed.

How to Book

  • Basic charters can be arranged 24–72 hours ahead off-peak
  • High season (Dec–Apr, Christmas/New Year, Full Moon weeks) needs weeks to months of lead time
  • The norm is a 50% deposit to confirm, balance in cash on the day
  • Platform bookings (GetYourGuide) offer free cancellation up to 24 hours
  • If the operator cancels for unsafe weather, expect a reschedule or full refund
    • 📅

    Book With Free Cancellation

    Use a platform with weather-protected free cancellation in shoulder season, so a forecast change doesn't cost you a deposit.

    Best Time for a Private Charter

    The park closes annually for monsoon restoration — plan around it.

    Best

    Dec – Apr

    Calmest seas and clearest skies — peak season for private charters, so book several weeks ahead.

    Good

    May – Oct

    Shoulder season — greener, cheaper and less crowded, with occasional rain. Easier to book a private boat last-minute.

    Closed

    1 Nov – 15 Dec

    Ang Thong National Marine Park is officially closed for monsoon restoration — plan an alternative like Koh Tao or Koh Phangan.

    Common Question

    Private charters become cost-competitive at around 6 to 8 passengers, where the per-person price roughly matches a shared speedboat tour while giving the whole group total control of the itinerary. For couples or pairs, a shared or semi-private tour from Koh Samui is usually the better value, since a private speedboat charter for two can run several times the per-person cost of a group trip. If you'd rather paddle than motor, our kayaking tours guide covers the kayak-focused options instead.
