About this tour
When Tom from our BugBitten team took the Koh Yao Sun Smile speed boat from Railay, it was a straightforward 1-hour hop across turquoise water to Koh Yao Yai. The boat departs from a modest floating pier at Railay East and whisks you over the Andaman Sea to a quieter island that feels worlds away from Railay's climbing-scene hustle. It's a no-fuss transfer with basic travel insurance bundled in, though you'll need to get yourself to the pier. The journey works year-round, with three daily slots in peak season (Nov–Apr) dropping to one afternoon departure when seas calm down in low season.
Highlights
- Speed boat cuts through Andaman waters in just one hour.
- Floating pier departure point at Railay East, easy to locate.
- Operates daily all year, including monsoon shoulder seasons.
- Basic travel insurance included in the ticket price.
- Multiple departure times during high season offer scheduling flexibility.
- Koh Yao Yai side feels quieter and less touristy than Railay.
- Sea conditions regularly monitored; cancellations refunded in full.
What to expect
Tom boarded at the small floating pier on Railay East's quieter side — not the main beach — which was easy enough to find but worth confirming the exact spot with your accommodation the night before. The speed boat fills up with a mix of backpackers, families, and island-hoppers, then throttles out into open water. Once you're clear of the limestone cliffs, you get 50 minutes of open-sea spray and decent views across the bay. The ride is genuinely fast and can be bouncy in chop, so brace yourself against the handrails and expect the occasional jolt.
Arrival at Koh Yao Yai's pier is quick and efficient — staff helped passengers disembark without fuss. The island itself is noticeably less developed than Railay, with a more laid-back vibe and fewer tour operators trying to sell you things. Tom found the journey useful for reaching less-trampled accommodation, though the speed boat itself isn't a sightseeing experience — it's transit done well.

Good to know
This is a reliable workhorse transfer with no surprises. If you want to skip Railay's crowds and stay on a quieter Phang Nga island, it's the straightforward route. Daily sailings and multiple departure slots in high season mean flexibility. Insurance is included, so one fewer box to tick.
Speed boats are loud and lumpy in any swell; if you're prone to motion sickness, take tablets beforehand. The floating pier means there's no shelter while waiting, and the boat doesn't collect from hotels — you must reach Railay East on your own. Infants need to sit on a lap, and the journey isn't suitable for anyone with spinal issues, heart conditions, or pregnancy. Bad weather or rough seas can trigger delays or cancellations (full refund applies, but it's still disruptive). In low season, there's only one afternoon departure, so you've got limited timing options.
Seasickness tablets if you're unsure; water and a light layer for spray; secure your valuables in a dry bag. The ride is 1 hour; the seat is basic plastic bench-style, so don't expect luxury.
