How to get from Koh Kradan to Koh Bulon
Ferries from Koh Kradan to Koh Bulon Lae
Koh Kradan and Koh Bulon Lae are two of the Trang and Satun archipelago's quieter islands, and travelling between them means island-hopping by boat rather than a single direct crossing. There is no scheduled ferry running the whole way non-stop; the journey is typically covered with a connection, usually routed via the mainland pier or a nearby hub island, using speed boat operated by Bundhaya Speed Boat and Satun Pakbara Speed Boat Club.
Journey time, price and departures
Allow around the scheduled journey time for the full crossing, including the connection. The lowest fare currently available is ฿900 per person; final pricing depends on the operator and how far in advance you book. Departures run 2, and because this is a multi-leg route, timings between the two legs need to line up — check the exact connection times shown on the booking page before you commit to a same-day itinerary.
When this route operates
This is a seasonal route: boats connecting Koh Kradan and Koh Bulon Lae run only during January to April and October to December, in line with the calmer sailing conditions in the Andaman Sea. Outside these months the crossing is suspended and the booking engine will not show departures. If you are travelling outside January to April and October to December, check the reverse listing for boats from Koh Bulon Lae back to Koh Kradan for the same seasonal window, or plan your island-hopping itinerary around the months when the route is active.
Departure and arrival points
Boats depart from Koh Kradan on Koh Kradan and arrive at Koh Bulon on Koh Bulon Lae. Both islands have limited pier infrastructure, so boarding is often by longtail transfer between the main boat and the shore — wear shoes you don't mind getting wet and keep valuables in a dry bag. On board, expect basic onboard facilities; these are small island-hopping boats rather than large ferries, so space for luggage is limited.
Good to know before you book
Koh Kradan is known for its powder-white beach and clear shallow water, while Koh Bulon Lae is smaller and less developed, with a handful of beach bungalow resorts and far fewer visitors. Because the route relies on a connection rather than a direct sailing, build in some buffer time between legs, particularly if you also need onward transport to or from the mainland the same day. Luggage space is limited on the smaller boats used for the final leg, so pack light if possible.

Frequently asked questions
Do I need to print my ferry ticket or is mobile ok?
You don't need to print your ticket. Your boarding voucher is in your account: open Bookings, then View trip details, and click Download PDF. On the day of travel, show the QR code on it — on your phone is fine — to the ferry operator staff at the pier named on your ticket, and they will direct you to your boat.
If you'd prefer paper, print the PDF yourself.
What happens if my ferry is cancelled due to weather?
We are sorry when weather stops a sailing. Ferries usually run in rain; speedboats are more often stopped by rough seas.
If your trip is cancelled because of weather, your booking in Bookings shows a message once our team has confirmed the cancellation. You can then either move to the next available service with Change this booking, or cancel with Cancel & refund for a full refund.
If the sailing is running but you choose not to travel, the normal cancellation policy applies.
Why is my account locked?
We lock an account for a short time after several failed sign-in attempts in a row. It is an automatic safety measure: it stops someone else guessing your password, and it happens whether or not the person typing was you.
You do not need to contact us. The lock lifts on its own — see How long am I locked out for?
What is the difference between a locked and a blocked account?
Locked is automatic and temporary. It happens after repeated failed sign-in attempts and it lifts by itself — within a minute in most cases.
Blocked is a decision made by our team, and it does not lift on its own. If your account is blocked you will need to contact us; waiting will not change it, and neither will resetting your password.
If you are not sure which applies to you, get in touch and we will tell you.
How do I unlock my account now?
Wait, and try again. Every lock lifts on its own — a minute the first time, and never more than an hour however many attempts have failed. There is nothing to click and nobody to contact.
If you have forgotten your password, do not keep guessing: each wrong attempt makes the next wait longer. Use Forgot password instead. Resetting your password gets you straight back in.
My account locked but I never tried to sign in
Then someone else was trying to sign in as you, and the lock did its job — it stopped them.
Your account is safe: a lock means the attempts failed. Nobody got in. You do not have to do anything, and the lock will lift on its own.
We would still recommend two things:
- Change your password, especially if you use the same one on another website.
- Add an authenticator app in your account security settings, so a password alone is never enough to sign in as you.
If you get these repeatedly, contact us and we will look into it.
