How to Get from Koh Lanta to Koh Samui

Leaving the rugged, sunset-drenched shores of Koh Lanta for the palms of Koh Samui takes you across the heart of Southern Thailand. The route runs from the Andaman Sea on the west coast to the Gulf of Thailand on the east, from the quiet, bohemian vibes of Lanta to the resorts and nightlife of Samui. It is a classic cross-country trip that rewards you with a changing landscape of limestone karsts and rubber plantations across the peninsula.

Both islands have stunning beaches, and the trip between them is an adventure in itself. You swap the long, sandy stretches of Klong Khong for the coconut groves of the Gulf. Because the islands lie on opposite coasts, the trip combines road and sea travel. Flying means going via Krabi: Bangkok Airways flies direct between Krabi and Samui in about 50 minutes,^[1] but you add transfers on both sides. Whether you choose a budget-friendly shared van or a private transfer, you can book your trip on GoAsia.cc.

Koh Lanta to Koh Samui by Van

For most independent travelers, the shared minivan is the go-to way to reach Koh Samui. A single ticket covers your whole journey: pickup on Koh Lanta, the car ferry off the island, the long drive across Surat Thani province and the final ferry crossing to Koh Samui. On booking platforms the ticket costs about $30 and the journey takes from about 8 hours (October 2026).^[2]

From Donsak, the final crossing to Koh Samui takes about 1 hour 30 minutes.^[3] Raja Ferry runs car ferries from Donsak to Lipa Noi pier on Koh Samui every hour from 05:00 to 19:00.^[4] Vans usually make stops at service stations or roadside cafes where you can stretch your legs, use the restroom and grab a Thai snack or a cold coffee.

Koh Lanta to Koh Samui by Ferry

You cannot do the whole trip by boat, because the Thai mainland is in the way. The "ferry" option is a combined road and boat ticket with the sea crossing from the mainland as its highlight. On booking platforms it costs about $31 and takes from about 9 hours (October 2026).^[2]

The trip starts with a pickup on Koh Lanta and a transfer to the mainland. The middle part is a scenic overland drive through the lush greenery of Southern Thailand. The last stretch is the big car ferry across the Gulf of Thailand, with open-air decks where you watch the islands appear on the horizon. It is a relaxing way to end a long day of travel as you approach Koh Samui.

Koh Lanta to Koh Samui by Private Transfer

If you travel with family or friends, or value privacy and comfort above all else, a private transfer is the premium way to make the cross-country trip. On booking platforms, prices run from about $249 to $310 per vehicle depending on the class, and the journey takes about 9 hours (October 2026).^[2] The options include economy cars, SUVs for up to 4 passengers and 9-seat vans for big groups.

The main advantage is door-to-door service and a flexible schedule. You do not wait for other passengers to be picked up or dropped off, and in a private car you control the air conditioning, the music and the stops. It is the most stress-free way to move between the Andaman Sea and the Gulf.
