Koh Tao is known primarily for diving and water activities rather than museums or historical monuments. Most 'sightseeing' focuses on natural sites, dive sites, and viewpoints.
Good to know
Good to Know
- Koh Tao is known as 'Turtle Island' due to its historical abundance of sea turtles, though they are now less plentiful; you may still see green and hawksbill turtles in specific areas like Shark Bay.
- The island offers year-round diving thanks to sheltered bays, though the best visibility is typically January–April and October (before the monsoon). Avoid October–December when monsoon conditions bring rough seas.
- Many dive sites are accessible from shore via snorkeling directly from beaches; you do not need a boat for basic snorkeling in places like Sairee Beach, Tanote Bay, or Hin Wong Bay.
- Arrive early at popular viewpoints (John Suwan, Koh Nang Yuan) to avoid crowds, especially during high season (November–March).
- Use reef-safe sunscreen when snorkeling or diving to protect coral; many sources emphasize avoiding damage to the delicate marine environment.
- If planning to visit Ang Thong Marine Park as a day trip, book tours from Koh Samui or Koh Phangan—no direct ferry service exists from Koh Tao.
- Most snorkeling spots offer excellent accessibility; you can enter the water directly from many beaches and explore underwater coral and fish without needing a full diving course.
- Koh Tao collects a modest 20 THB (~$0.60) per-visitor fee at the pier to fund marine conservation efforts due to tourism pressures on the island's coral reefs.
