Ko Tao: The Cheapest Place in the World to Learn to Dive, and What Else Is There

Ko Tao produces more PADI certified divers than anywhere else on earth. The PADI Open Water certification costs 10,000-13,000 baht (around USD 270-350) for a 3-4 day course that includes classroom sessions, confined water training, and four open water dives. The same certification costs USD 400-700 in most Western countries. The quality is genuine – Ko Tao’s dive schools are among the most heavily certified in Asia, water temperatures hover at 28-30 degrees Celsius year-round, and visibility from March through October reaches 20-30 metres. If you have ever considered getting certified, this is the most rational place to do it.

The island itself is small: 21 square kilometres, about 80,000 tourists annually, a ferry ride of about 2 hours from Chumphon or 1.5 hours from Koh Samui. The main village is concentrated around Sairee Beach on the northwest coast, which has the highest density of dive shops, restaurants, and accommodation.

Diving

The dive sites vary considerably in depth and difficulty. Chumphon Pinnacle, 40 minutes by boat from the main piers, descends to 36 metres and reliably produces large groupers, barracuda schools, and occasional whale shark sightings from March through May. Sail Rock (between Ko Tao and Ko Phangan) is a chimney dive where you descend through a narrow vertical passage and emerge at 24 metres; visibility here is consistently excellent. Southwest Pinnacle for advanced divers offers coral-encrusted walls and strong currents.

For beginners and snorkelers, Shark Bay (properly called Ao Leuk) has blacktip reef sharks visible from the surface in shallow water – they are smaller and more docile than their name suggests, and excellent for a first wildlife encounter. Koh Nang Yuan, a three-island cluster connected by sandbars accessible by a short boat trip, is the best snorkelling day from the main island.

The Beaches

Sairee is the main beach and the liveliest. Chalok Baan Kao on the south coast is quieter and faces west for sunset views. The remote east-coast bays – Ao Tanote, Ao Leuk, Ao Hin Wong – have clearer water and more coral but require a scooter or boat to reach. Renting a scooter (300-400 baht per day) is the practical way to explore the island beyond Sairee.

Where to Stay

Sairee has the widest range of accommodation from backpacker hostels at 300-500 baht per dorm to mid-range beach bungalows at 1,500-3,000 baht. Most dive schools offer package deals that include accommodation with the course, which represents good value. Jamahkiri Resort on the south coast is the island’s luxury option with an infinity pool and views across the gulf.

Practical Notes

The best season runs March through October. November through January brings northeast monsoon weather with rougher seas and reduced visibility. Ferries from Chumphon are the most reliable access point from the mainland; book in advance during July and August. The ferry combinations from Bangkok take about 6-7 hours total.

Ko Tao is not for people who want a quiet beach holiday without diving activity. It runs on dive school culture: communal meals in beach bars, debriefs after dives, recommendations exchanged between courses. If that’s not what you came for, Koh Lanta or Koh Kood offer calmer alternatives.
