General information about Koh Ngai

Koh Ngai, or Koh Hai, is a small island in southern Thailand and belongs to the province Krabi. It is located in the Andaman Sea, between the famous islands of Koh Lanta and Koh Lipe, and is about 14 kilometers from the mainland. With a size of only 5 square kilometers, this island is mini small. It has a dense jungle, a few lovely resorts and not to forget an absolutely breathtaking 2-kilometer-long palm lined beach that makes Koh Ngai a true Thai dream island. Also beautiful is the directly offshore house reef, where you can watch countless colorful fish while snorkeling!

Most of the resorts and bungalow complexes also run a small restaurant that provides food and drinks. From time to time, you will also come across a small, cozy beach bar where you can enjoy best the phenomenal sunsets of Koh Ngai. A diving school has also set up here. However, there is no ATM on this quiet island and also there are no real shopping facilities. Be sure to bring enough cash and buy everything you need for your vacation on the mainland beforehand.

The best time for your visit is from November to the end of April because in this period the monsoon is already over. In the rainy season, such as July and August, you must expect heavy rainfall, ferries do not run regularly, and many hotels are closed. Even in October, you have no guarantee for good weather.

Showers are taken outside, and electricity is only available during the day.

There is already a little bit of Robinson Crusoe feeling. The whole team was fantastic, and the bar provides guests with fresh coconuts, cold beer and freshly cooked curries. For backpackers traveling to Koh Ngai and looking for a cheap accommodation, this camp is certainly the right choice!

    That beach looks particularly inviting! And it’s so cool that you can also do jungle trekking while you’re there, added bonus!

  2. We’ve been talking about wanting to be somewhere warm, and that definitely fits the bill. I’m normally someone who can’t sit still when I’m away, but I’m very much persuaded that a hammock here, followed by a big swim, would be entirely perfect. And I’d be really happy to get that Robinson Crusoe feeling – it’s still one of my favourite books!

  3. What a beautiful place. Makes me want to grab a hammock and jump on a plane (or a few) … and boat. I love the photos too. So relaxing and peaceful.

  4. We are travel bloggers and still haven’t been to Thailand! What’s wrong with us? LOL Soon though, very soon we are hoping to visit. This sounds like a great place to stay!

  5. What a beautiful place Koh Ngai is! It seems so idyllic and the perfect place to take photographs. Did you go jungle trekking?

  6. I really can’t wait to get back over to Thailand and this time to fully explore the islands, they are just completely stunning, we will be adding this to our list!
