Plan your Koh Kradan to Koh Mook transfer with updated ferry times, prices, travel tips, seasonal information, and practical advice for combining two of Thailand’s most beautiful Trang Islands.
Traveling from Koh Kradan to Koh Mook is one of the easiest island transfers in Thailand’s Trang Islands. The two islands are only a few kilometres apart, and scheduled speedboats can make the crossing in around 10–15 minutes.
The route is particularly useful for travelers who want to combine Koh Kradan’s beaches and snorkeling with Koh Mook’s more developed village atmosphere and access to the famous Emerald Cave.
Current 2026 schedules show several departures during the late morning and early afternoon, although services are seasonal and can change according to weather and demand. Bundhaya Speed Boat, for example, currently lists the Koh Kradan–Koh Mook route at 10 minutes and THB 300 per person, with the service operating seasonally.

Current Koh Kradan to Koh Mook ferry times
Published schedules for 2026 show several possible departures. One current schedule lists:
- 10:45 → 11:00 — Satun Pakbara Speed Boat Club
- 10:50 → 11:00 — Bundhaya Speed Boat
- 11:30 → 11:45 — Tigerline Travel
- 12:15 → 12:30 — Satun Pakbara Speed Boat Club
- 13:50 → 14:00 — Bundhaya Speed Boat
- 14:30 → 14:45 — Tigerline Travel
Not every departure operates every day or throughout the year, so these should be treated as representative published times rather than a fixed year-round timetable.
Another current timetable shows the earliest regular services at around 10:45–10:50, while the final listed service can be around 13:50. This difference between published schedules is a good reason to confirm the departure for the specific travel date.
How much does the ferry from Koh Kradan to Koh Mook cost?
A standard scheduled speedboat currently costs around THB 300 per person on the main operators.
For example, Bundhaya lists the route from THB 300 per person, with a journey time of approximately 10 minutes.
Other published fares can vary depending on the operator, departure, booking conditions and season. Some listings show fares below or above THB 300, so it is better to regard THB 300–400 per person as a practical planning range rather than assuming that every boat has exactly the same fare.
Private boats are considerably more expensive but provide greater flexibility.
Which boat should you take?
Scheduled speedboat
For most travelers, a scheduled speedboat is the simplest choice.
Advantages include:
- Very short crossing time
- Fixed departure times
- Straightforward luggage arrangements
- Lower cost than chartering a private boat
- Easy connection between the two islands
With the crossing taking only around 10–20 minutes, there is little reason to pay a substantial premium for a private boat unless the schedule does not suit your itinerary.
Private or shared longtail boat
A longtail boat can be useful when you want more flexibility or are traveling with several people.
In the Trang Islands, shared longtail services can operate between beaches and islands during the high season. Published local information indicates that shared longtails between Koh Mook and Koh Kradan can cost around THB 300 per person, while a private longtail may cost approximately THB 1,000 for the whole boat, depending on the arrangement and destination.
Private boat prices are negotiated locally and can vary considerably, so they should not be treated as a fixed fare.
Where does the boat leave from on Koh Kradan?
This is one of the important differences between this route and conventional mainland ferry services.
Koh Kradan does not have a large conventional ferry terminal. Speedboats commonly collect passengers from the beach area in front of resorts or designated beach pickup points.
Published schedules, for example, identify Kradan Beach Resort as a departure point for some services to Koh Mook.
Your exact pickup location therefore depends on the operator and the service you have booked.
If you are staying at a resort on Koh Kradan, ask the reception desk where the boat will collect you. This is particularly useful because boarding may involve walking through shallow water rather than using a conventional pier.
Where will you arrive on Koh Mook?
Arrival arrangements also vary by service.
Some boats use Koh Mook Pier, while other island services can drop passengers at a beach such as Farang Beach, depending on the operator and route. Published schedules for the route show both Koh Mook Pier and Farang Beach as possible points associated with Koh Mook services.
This matters if your hotel is on the opposite side of the island. Before departing Koh Kradan, confirm exactly where your boat will arrive and arrange a local transfer if necessary.
How early should you arrive?
Because Koh Kradan uses relatively small island-boat facilities rather than a large ferry terminal, there is generally no reason to arrive extremely early.
A practical approach is to be at the designated pickup point 20–30 minutes before departure.
Allow additional time if:
- You have several pieces of luggage.
- You need to walk from your resort to the pickup point.
- The boat departs directly from the beach.
- Sea conditions are rough.
- You are traveling during the busy high season.
Keep phones, cameras and other electronics in a waterproof or dry bag. Beach boarding can involve shallow water and wet luggage.
What is the best time to travel?
The Trang Islands have a pronounced seasonal pattern, and boat services are affected by sea conditions.
Koh Kradan–Koh Mook speedboat services are generally associated with the main island-travel season. Bundhaya currently lists this particular route as seasonal, operating approximately from 15 October to 20 May.
During the wetter months, services can become less frequent or may be affected by weather and sea conditions. Travelers visiting outside the main season should therefore check directly with their accommodation or boat operator rather than relying on a timetable from another month.
Is Koh Kradan or Koh Mook better for a longer stay?
The two islands complement each other well.
Koh Kradan is particularly attractive for:
- White-sand beaches
- Clear water
- Snorkeling
- A quieter island experience
- Relaxing at a beach resort
Koh Mook is better suited to travelers looking for:
- A local village atmosphere
- More accommodation and restaurant choices
- Easier access to the Emerald Cave
- More opportunities to arrange local boat trips
- A slightly more developed island environment
For many travelers, staying on both islands makes more sense than trying to choose only one.
A simple itinerary could be:
Koh Kradan → Koh Mook → Koh Ngai
Alternatively, Koh Mook can be used as a base for exploring nearby islands and the Emerald Cave.
Combining Koh Kradan and the Emerald Cave
Koh Mook’s Emerald Cave is one of the main reasons travelers continue to the island after visiting Koh Kradan.
The cave is accessed from the sea and involves swimming through a dark passage before reaching a hidden interior lagoon surrounded by limestone cliffs.
The two islands are also commonly included together in Trang island-hopping trips, sometimes alongside Koh Chueak and Koh Ngai. Private longtail and speedboat trips can provide a more flexible alternative to a group excursion.
If the Emerald Cave is an important part of your itinerary, staying overnight on Koh Mook gives you considerably more flexibility than visiting only as part of a day trip.
Is the Koh Kradan to Koh Mook ferry worth booking in advance?
For a short crossing like this, advance planning is mainly about securing the correct departure time, rather than saving a large amount of money.
Booking or reconfirming approximately one day before travel is sensible, particularly during the main season.
Check:
- Departure time
- Exact pickup point on Koh Kradan
- Arrival point on Koh Mook
- Luggage allowance
- Whether the service is operating that day
- Whether the boat is affected by weather
Published timetables can differ between operators and booking sources, which is why the specific date matters. Current schedules show multiple departures, but they are not necessarily available every day throughout the year.
What happens if the sea is rough?
Boat services in the Trang Islands are weather-dependent.
The crossing is short, but speedboats can feel uncomfortable when the sea is rough. Departures may also be delayed, rescheduled or cancelled in poor conditions.
If you have a flight, train or other important connection from Trang on the same day, leave a generous buffer rather than relying on the shortest advertised crossing time.
Recommended Koh Kradan to Koh Mook plan
For most independent travelers, the easiest approach is:
- Check the available speedboat departures for your travel date.
- Choose a late-morning or early-afternoon service that fits your accommodation check-out.
- Confirm the exact beach pickup point with your Koh Kradan resort.
- Arrive at the pickup point 20–30 minutes before departure.
- Keep valuables in a waterproof bag.
- Confirm your Koh Mook arrival point before boarding.
- Arrange a local transfer if your accommodation is away from the arrival beach or pier.
With the islands so close together, the actual boat ride is rarely the difficult part. The most important details are confirming the departure point, operating date and arrival location.
