Ang Thong Marine Park Tours from Koh Tao

A longer journey, but absolutely worth it if you're based on Koh Tao. Here's how to do the day trip efficiently — without doubling back to Koh Samui.

Is It Worth the Trip from Koh Tao?

Yes — but it's a commitment. Koh Tao is approximately 75–80 km north of Ang Thong Marine Park, making it the furthest of the three main departure islands. The typical transit by speedboat is 90–120 minutes each way.

Dedicated "Koh Tao to Ang Thong" tours do exist and operate periodically, but availability is much more limited than from Koh Samui or Koh Phangan. If you can't find a direct option, the next best approach is to take the speed ferry to Koh Phangan and join a tour from there.

💡

Alternative: Base Yourself in Koh Samui for One Night

If you have flexibility, staying one night in Koh Samui gives you access to daily departures, widest tour choice and the most value. See our Koh Samui guide.

Your Options from Koh Tao

  • Direct Koh Tao day tour: Search for "Ang Thong tour from Koh Tao" — limited availability, especially outside peak season. Book as far ahead as possible.
  • Koh Tao → Koh Phangan ferry + Phangan tour: Take the speed ferry (45 min) and join a direct tour from Koh Phangan. Adds 2–3 hours to your day but gives more tour options.
  • Koh Tao → Koh Samui ferry + Samui tour: The most reliable option. Ferry takes ~2 hours, but Koh Samui offers daily departures and maximum tour choice.

    For Divers on Koh Tao

    If you're a diver already on Koh Tao, consider skipping Ang Thong entirely — the main draws (coral reef, fish) are of a similar standard to what you'll see diving around Koh Tao itself. Ang Thong's main appeal is the landscape: viewpoints, Blue Lagoon, limestone islands. Go for the scenery, not the diving.

    Visiting Ang Thong from Koh Samui or Koh Phangan Instead?

    For most travellers, these offer the best combination of tour choice, value and logistics.
