A detailed comparison of the two primary ways to reach Ang Thong Marine Park — comfort and speed. Updated March 2026.
Most travellers struggle to choose between the speed of a speedboat and the stability of a big boat. Here's exactly how they differ.
| Feature | Speedboat | Big Boat (Ferry Style) |
|---|---|---|
| Travel Time | 45–60 minutes | 90–120 minutes |
| Comfort | Bumpy, can be loud | Smooth, stable, 3 decks |
| Seasickness Risk | High (if rough) | Low (very stable) |
| Group Size | 20–43 people | 80–120 people |
| Best For | Active adults, groups | Families, motion sensitive |
If you have the budget and aren't prone to seasickness, choose the speedboat to see more. However, if you are travelling with young children or want a "chill" day out with a great lunch, the big boat is unbeatable value.
Once you've chosen your boat, here's what to book.
Speedboat and big-boat tours to Ang Thong Marine Park from Koh Samui both include snorkelling, kayaking and the Emerald Lake. For a change of scene, a Koh Tao and Koh Nang Yuan snorkelling day trip or a private charter around the archipelago make great add-ons. Live options below.
Speedboats are the choice for those who want to maximize their time inside the park rather than on the water.
Big boats are effectively floating restaurants and observation decks, offering a much more relaxed vibe.
