Bundhaya runs scheduled speedboats from Saladan to the same islands, if you’d rather stay over than go back the same day.
| Island | Crossing | From (one way) | Season listed |
|---|---|---|---|
| Koh Ngai | 30 min | ฿650 | 15 Oct–20 May |
| Koh Mook | 50 min | ฿900 | 15 Oct–20 May |
| Koh Kradan | 1 h 10 min | ฿950 | 15 Oct–20 May |
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.
Listings usually name Koh Mook (for the Emerald Cave), Koh Ngai and Koh Kradan. The fourth stop varies by operator.
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).
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.
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.
