Ko Tao, Thailand

Ko Tao has roughly 100 dive shops on 21 square kilometres of island. That density should tell you what the island is for. The underwater environment around it includes hard coral gardens, submerged pinnacles, and whale sharks passing through from March to May; the island offers one of the cheapest PADI Open Water certifications in the world. The combination makes Ko Tao a genuine diving destination rather than a place where diving is incidentally available. People come here specifically for it and tend to stay longer than planned.

Diving

PADI Open Water courses run about 9,000 to 10,000 baht (approximately USD 250 to 280) and take three to four days. Quality varies significantly across the 100-plus operators. Ban’s Diving Resort has a long-established reputation. Crystal Dive is another consistently recommended option. Avoid any school offering significantly below-market prices; the instruction quality reflects the economics.

The main dive sites: Chumphon Pinnacle (30 metres depth, frequent whale shark sightings), Southwest Pinnacle (large pelagic fish), and the HTMS Sattakut wreck (a deliberately sunk decommissioned warship at 30 metres).

Beaches and Snorkelling

Sairee Beach on the west side is the main strip: 2.5 kilometres of sand, consistent sunset views, the highest concentration of restaurants and bars. Good and can feel crowded in peak season (December through February, July through August).

Tanote Bay on the northeast is quieter with clearer water. Shark Bay on the southeast has a resident population of juvenile blacktip reef sharks in the shallows; snorkelling among them is the most reliable shark encounter without scuba gear. Snorkelling equipment rents for 100 to 150 baht per day from beach vendors.

Eating

The night market near Mae Haad pier opens from around 5pm and sells pad kra pao, som tam, and grilled meat skewers for 60 to 100 baht per dish. This is the best-value food on the island and where the food workers eat. Choppers Bar and Grill on Sairee does solid Thai standards and Western food at fair tourist-adjacent prices.

Getting There

Ko Tao has no airport. Fly to Koh Samui and take a Songserm ferry (about 1.5 hours), or fly to Surat Thani on the mainland and connect by ferry from Don Sak (about 3 hours). High-season departure ferries sell out; book ahead during Christmas-New Year and Songkran.

When to Go

November through February is the dry season with calmest seas. October is typically when Ko Tao pauses as the monsoon peaks; several businesses close for the month.
