Koh Ngai Information

Koh Ngai, also called Koh Hai, is located off the coast of Trang yet it belongs to Krabi Province. The island is mostly visited from Trang and the surrounding islands like Koh Kradan and Koh Mook. The easiest way to travel to Ngai is through Trang. You can catch a train from Bangkok’s Hua Lamphong Railway Station to Trang Railway Station and then get on a taxi or a minivan in order to reach Parkmeng Pier to catch a ferry to the Fantasy Resort & Spa which the check-in point of the island as it doesn’t have an actual pier. Via the sea is the most convenient and the most exciting way of transportation between the islands. A speedboat trip is available every day from several locations like Koh Phi Phi, Koh Lipe, Koh Lanta, Phuket, and of course Koh Mook, Koh Kradan, and Koh Bulon. There are no roads or motorized vehicles on the island apart from the longtail boats as the island is only around 4 kilometers long and 2 kilometers wide, the only transportation on the island is two-legged!

Koh Ngai Information

About Koh Ngai

Koh Ngai is one of Trang's islands yet, this small beautiful island belongs to Krabi Province. This island doesn't have a local life, it is only dedicated for tourism unlike its neighbor Koh Kradan. The only buildings on the island are restaurants and hotels.

Most of the resorts are located south as the widest stretch of sand is found there. The island is private and idyllic with the amazing scenery of the crystal clear water and the sandy white beach. The atmosphere is very quiet on the island which makes it an ideal place to chill, find peace, and take unforgettable photos.

Because everything on Koh Ngai is built around visitors rather than a village, the island suits travellers who want beach time, snorkelling and slow days rather than nightlife, markets or town amenities.

How to get to Koh Ngai

There is no airport on the island, so every arrival comes by water. Our booking system currently lists 59 routes bookable routes serving Koh Ngai, connecting it with the mainland and with the surrounding Andaman islands.

Services are sold as through tickets, so a single booking can combine a mainland leg with the island crossing where the operator runs that combination. Enter your travel date on the search form to see the exact services, timings and vehicle types available on the day you want to travel — availability on island routes changes with the season.

Connections from the mainland

From the Krabi side, Ao Nang is a common starting point for travellers coming from Krabi Town, Krabi Airport or the Railay area. From the south, the Satun coast links the island into the chain of routes running towards the Malaysian border.

Island-to-island connections

Koh Ngai sits in the middle of a well-connected island chain, which makes it easy to include in a longer Andaman itinerary. Direct connections listed in our system include Ao Nang, Koh Bulon, Koh Jum, Koh Kradan, Koh Lanta and Koh Lipe, plus 8 more destinations.

Travellers heading south often use the island as a stop between Koh Lanta and Koh Lipe, while those heading north continue towards Koh Jum and Ao Nang.

Operators serving Koh Ngai

Several operators sell tickets on this island network, including Bundhaya Speed Boat, Lanta Petpailin and Satun Pakbara Speed Boat Club. Each runs its own timetable and its own combination of stops, so the operator you travel with depends on the route and date you choose. Compare several operators and the other operators listed for your route side by side before you book, and check the ticket conditions shown at checkout.

Popular routes to and from Koh Ngai

Tickets on these routes start from ฿300. Prices vary by operator, season and how far ahead you book.

Arriving on the island

Most services arrive at the beaches on the southern and eastern side, where the resorts are concentrated and the widest stretch of sand is found. Some boats moor offshore and transfer passengers to the beach by longtail, so expect a short wet landing on some services and pack accordingly — a dry bag for phones, cameras and documents is worth having.

Your confirmation shows the pick-up or meeting point for your specific service. Because the island is small, transfers between the pier area and your accommodation are short, and many resorts are within walking distance of the arrival beach.

Practical travel information

  • Plan around the season. Andaman island services are weather-dependent, and schedules on some routes are reduced or suspended outside the main season.
  • Book connecting legs with a buffer. If you have a flight or an onward transfer, allow time between arrival and departure rather than booking back to back.
  • Bring cash. Facilities on the island are limited to restaurants and hotels, so card acceptance and cash machines cannot be relied on.
  • Travel light where you can. Beach landings and small boats make oversized luggage awkward to handle.
  • Check your baggage allowance. Conditions differ between operators and are shown with each ticket.

What to see and do

The main draw is the beach itself: clear shallow water, white sand and calm swimming close to shore. Snorkelling straight off the beach is easy, and the reefs around the island and its neighbours are the reason most people come.

From the island you can join day trips towards the surrounding islands and sea caves, or simply take the short crossing to Koh Kradan for the day. Sunrise and sunset over the water are the standout photo opportunities, and with no traffic or town noise, the evenings stay quiet.

FAQ

Frequently asked questions

What are the tourist seasons ?

Phuket

Phuket really just has two seasons, which are known as "high season" and "low season" (or "green season"). During the low season months (May–September), boat numbers are reduced. During the high season (October–April), boats to the surrounding islands are increased so you will have some more options.

Koh Samui

There are three distinct weather seasons on the tropical island of Koh Samui: the dry season (December until February), the hot season (March until August) and the rainy season (September until November).

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.

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 long am I locked out for?

The first lock is one minute. If sign-in keeps failing after that, each further lock lasts longer:

  • 1st lock — 1 minute
  • 2nd lock — 5 minutes
  • 3rd lock — 15 minutes
  • 4th lock and after — 1 hour

An hour is the longest you will ever be locked out. You get five attempts before the first lock, and as soon as you sign in successfully everything resets — the next time you mistype, you start again at one minute.

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.

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?
