Staying a night instead

Bundhaya runs scheduled speedboats from Saladan to the same islands, if you’d rather stay over than go back the same day.

These are Bundhaya's island-hopping transfers, not day tours. Out of season they don't run, which is a fair guide to when the sea on this side is calm enough for small boats.Checked · Source: Bundhaya Speedboat: routes

They run 15 October to 20 May, and the park’s smaller islands close 16 May to 14 October. A dry-season date is the safe choice.

Questions about Koh Lanta

Which islands are on the Koh Lanta 4 island tour?

Listings usually name Koh Mook (for the Emerald Cave), Koh Ngai and Koh Kradan. The fourth stop varies by operator.

Can you do the 4 island tour in the rainy season?

Some tours run, but the sea is rougher. Bundhaya's scheduled speedboats to Koh Ngai, Koh Mook and Koh Kradan only run from 15 October to 20 May (checked 21 Oct 2026).

Longtail or speedboat?

Longtails are slower and closer to the water. Speedboats reach the islands faster, which leaves more time at each stop. Both versions are listed on GetYourGuide.

How much is the Koh Lanta 4 island tour?

On GetYourGuide on 21 Oct 2026: from US$29.83 by longtail, US$41.39 with a beach lunch on Koh Kradan, US$46.69 by speedboat and US$276.43 for a private longtail.

How do you get to Koh Ngai from Koh Lanta?

Bundhaya runs scheduled speedboats from Saladan: 30 minutes to Koh Ngai (฿650), 50 minutes to Koh Mook (฿900) and 1 h 10 min to Koh Kradan (฿950). They run 15 October to 20 May.
