Leaving behind the upscale resorts and coconut groves of Koh Samui for the rugged, diver-centric shores of Koh Tao feels like a true transition into the heart of the Gulf of Thailand. While Samui offers every luxury imaginable, Koh Tao is where the pace slows down and the focus shifts entirely to the turquoise depths of the sea. The journey between these two islands is one of the most popular routes in the country, cutting through sparkling waters that hint at the world-class snorkeling awaiting you at the finish line.
Because Koh Tao has no airport, the only way to reach this granite-fringed paradise is by sea. The crossing is relatively short, but the experience can vary significantly depending on whether you choose the faster catamaran or the slower ferry. Whether you are heading over for a day trip or moving on for a week of scuba certification, the transit is a scenic highlight of any Gulf itinerary. You can easily secure your spot on any of these vessels by booking through GoAsia.cc to ensure your island hopping remains stress-free.
Koh Samui to Koh Tao by Catamaran and Ferry
Lomprayah sails from Koh Samui (Pralarn Pier) to Koh Tao (Mae Haad Pier). In mid-October 2026 its booking page listed a catamaran at 08:00 taking 1 hour 30 minutes, a catamaran at 12:30 taking 1 hour 45 minutes for 700 baht (about $21), and a slower ferry at 11:00 taking 2 hours 30 minutes for 550 baht (about $16).[1] Sailings and fares change by season, so confirm them for your date when you book.
Catamaran Services
The catamaran is the preferred choice for those who value speed. These large, dual-hulled vessels slice through the waves with less rocking than smaller boats, which is a plus if you are prone to seasickness. The outdoor decks provide a fine vantage point for watching the Samui coastline fade away. At 1 hour 30 minutes to 1 hour 45 minutes, it is the most efficient way to travel.[1]
Ferry
For a more relaxed pace, the ferry is the cheaper option. It takes longer than the catamaran (2 hours 30 minutes on the 11:00 sailing) and cost 550 baht (about $16) when we checked.[1] It suits budget-conscious travelers who are not in a rush.

Tips for Traveling from Koh Samui to Koh Tao
- Book in Advance: During the peak diving season or around the Full Moon Party dates in nearby Koh Phangan, these boats can fill up quickly. Secure your tickets early to get your preferred departure time.
- Check the Pier: Koh Samui has several piers, and Lomprayah offers sailings to Koh Tao from Pralarn Pier, Nathon Pier and Bangrak Pier.[2] Double-check which one your boat departs from, as they are located on different sides of the island.
- Manage Seasickness: Afternoon winds can create swells in the Gulf of Thailand. If you are sensitive to motion, choose the larger catamaran and sit toward the back of the boat where the movement is less intense.
- Luggage Handling: Be prepared to carry your own bags down the pier, and keep your valuables in a waterproof daypack.
- Arrival at Mae Haad: The Lomprayah sailings arrive at Mae Haad Pier in Koh Tao.[1] From there you can continue to Sairee Beach or Chalok Baan Kao by taxi or resort pickup.
