The morning opens on the pier with salt and coffee: a low roar of engines, crew calling names, and the sea already brightening under a quickening sun. The speedboat cuts across the Gulf of Thailand, the wind pushing past and the horizon widening until Koh Tao first appears as a green pinprick, then as the pale crescent of sand at Koh Nang Yuan. On arrival the water dares you—cup-clear, warm, and full of color. Snorkeling sites like Hin Wong (Rock Bay) reveal shallow coral gardens dense with butterflyfish, parrotfish, and the occasional green turtle.

Arrive early for pickup
Pickup windows start early—be ready at your hotel lobby to avoid delays and secure your preferred seat on the speedboat.
Use reef-safe sunscreen
Apply reef-safe sunscreen before boarding and bring a small travel bottle for reapplication to protect corals and skin.
Bring water shoes
The sandbar and some reefs are covered in sharp shells and rock—water shoes protect feet when entering and exiting the water.
Secure valuables in a dry bag
Speeds and spray can soak backpacks; keep phones and passports sealed in a dry bag or leave valuables at the hotel.
Reef-safe sunscreen
Protects skin and the reef; required for repeated sun exposure on the water.
Snorkel mask (personal)
Personal masks often fit better than rental gear and reduce fogging during long swims.
Water shoes
Protect feet on the sandbar, rocky shorelines, and when entering shallow reefs.
Light dry bag
Keeps electronics and documents dry from spray and accidental immersion.
