Koh Ngai wasn't at the top of our list when we started our Thailand trip almost ten years ago. Phuket, Koh Phi Phi, and Koh Samui were our favorites back then. But recently, we heard so many great things about Koh Ngai from other travelers, for example, how fantastic the island is for couples, that we simply had to try it out. And what a great decision it was! In our opinion, Koh Ngai is the most beautiful island in all of Thailand – with its towering palm trees, crystal-clear water, and breathtaking views. Yes, it's quite small, but it offers everything you could possibly want for a perfect beach vacation.

Koh Ngai is located in southern Thailand, off the Andaman coast, and belongs to the Trang archipelago, which also includes Koh Mook, Koh Kradan, and sometimes Koh Lipe. It is undoubtedly one of Thailand's most beautiful islands and the perfect place for a dreamy beach right on your hotel doorstep. We visited Koh Ngai in February and chose the Thapwarin Resort for our four-day stay. All the resorts are located directly on the main beach and surrounded by jungle. We highly recommend the Thapwarin, not for its luxury, but for its unique charm and location.

Overview of Koh Ngai

Koh Ngai officially belongs to the province of Krabi, but is also located near Trang. The island is simply laid out: 4 km by 2 km in size, with a long beach aptly named "Main Beach." There are no roads, no towns, and certainly no supermarkets. The island's interior is covered in jungle, and although you can hike to viewpoints and go birdwatching, most visitors come solely for the beach.

What the island offers travelers is the epitome of a perfect postcard beach scene: soft, golden sand, clear, emerald-green water, a vibrant coral reef, hornbills soaring overhead, and picturesque views of the surrounding islands. Those who want to avoid the tourist crowds of Thailand will find Koh Ngai ideal. Here you'll find around a dozen comfortable resorts, each with its own restaurant, yet still enjoy the peace and seclusion of the island.

The coral reef just offshore is only a few strokes from the beach, so snorkeling and kayaking are popular activities. During our visit, schoolchildren were on a field trip to learn all about the coral reef and the importance of sustainability (which was really great). Hornbills are the most recognizable bird species here, and you can often see them perched high in the trees or flying over the beach.

For us as a couple, Koh Ngai was a relaxing and romantic holiday. We simply enjoyed leisurely days on the beach – sunbathing and swimming – and in the evenings, all we did was watch the sunset and enjoy a few drinks in the charming beach bars. The island is also ideal for families with small children, as the water is shallow at high tide.

Our magical experience in Koh Ngai

As mentioned before, we visited Koh Ngai in February, which was the perfect time weather-wise. We couldn't have asked for better conditions: a pleasant speedboat ride, bright blue skies every day, and mirror-like water at the beach. Our route took us from Phuket via Koh Phi Phi and Koh Lanta to Koh Ngai. We bought the speedboat ticket in Phi Phi Don.

We still fondly remember our first arrival in Koh Ngai – it was truly magical. The beach was pristine, the water sparkled, the longtail boats glided across the mirror-like surface, and the jungle hills stretched out in mesmerizing patterns. The photos below unfortunately don't do justice to the beauty of this place. All the passengers on board were smiling and couldn't wait to get ashore by longtail boat.

As we disembarked from the longtail boat with our backpacks and dipped our feet in the water, we set off for the resort on the main beach. It was 3 p.m., the sun was blazing, and to be honest, we arrived in Thapwarin drenched in sweat. But the stunning scenery along the way motivated us to tackle the long and strenuous hike with our backpacks. After arriving in Thapwarin and checking in, we were escorted through the lush grounds to our bungalow. Finally, we could breathe a sigh of relief and enjoy the paradise around us.

We hadn't planned much for our four-day stay on Koh Ngai. The days flew by: we went swimming and snorkeling almost every day, took long walks on the beach at low tide, searched for hornbills hiding in the trees, napped, got massages on the beach, and enjoyed the sunset every evening from a cozy little beach bar. It really couldn't have been more relaxing. Nevertheless, there was one moment that has stayed with us.

After enjoying our third sunset from our favorite beach bar, we returned to the resort and were surprised by a blood moon that bathed the island in a warm light. We could hardly believe our luck! It was incredibly beautiful. And of course, it made for fantastic photos, especially with the orange-crimson glow illuminating the longtail boats anchored along the shore. These are travel experiences you never forget.

Since there are no supermarkets or grocery stores on the island, you're forced to eat almost all your meals at the resort. Luckily, Thapwarin had a wonderful on-site restaurant with a sea view. We had breakfast, lunch, and dinner there every day – and although the bill was quite high in the end, it was worth it. We enjoyed spending our evenings at the resort, chatting with other guests and simply admiring the view. After four nights, we were completely relaxed and ready to continue our island tour in the south.

How to get to Koh Ngai

Koh Ngai is best reached as part of an island-hopping tour in the Krabi region. Getting there directly from Bangkok is somewhat complicated, and even the alternative route from Pak Meng Pier near Trang Town isn't entirely straightforward. We therefore recommend arriving from Koh Lanta or Koh Phi Phi after spending a few days there (as we did).

From Koh Phi Phi or Koh Lanta

We booked a speedboat ticket from Koh Phi Phi to Koh Ngai, with a stopover at Koh Lanta. This was a great option, as we had thoroughly enjoyed our stay on Koh Phi Phi and had only recently visited Koh Lanta. The crossing was calm in February, but we've heard that it can get a bit rougher in this part of the Andaman Sea during the rainy season. As far as I remember, the journey from Koh Lanta to Koh Ngai took about 40–60 minutes. Note that most speedboats dock in Koh Ngai, and from there you'll be taken to the beach by longtail boat.

From the mainland (Trang)

You can fly from Bangkok to Trang and from there take a taxi to Pak Meng Pier to catch a speedboat to Koh Ngai. We actually did this route in reverse when leaving Koh Ngai. However, we wouldn't recommend it, as it was quite complicated logistically.

First of all, the speedboat from Koh Ngai didn't take us directly to Pak Meng Pier. What should have been a 30-minute ride took several hours because the boat picked up passengers from Koh Kradan, and we had to wait a long time. When we finally arrived at the pier, there were no taxis left to take us to Trang for our flight to Bangkok. Luckily, we met a very friendly local family who noticed our predicament and offered us a ride into town. So, the whole thing had a silver lining after all!

Important tips:

  • Check the time of year and sea conditions: The dry season on Koh Ngai lasts from November to April and is generally considered the best time for boat trips. From May to October, speedboat services may be limited or cancelled due to bad weather.
  • Bring suitable luggage: As the speedboats anchor offshore and passengers are taken to the beach by longtail boats, it's advisable to bring easily portable luggage. A backpack with shoulder straps, for example, is better than a suitcase. Keep in mind that you may have to carry your bags to the resort yourself unless a porter is arranged for you – so pack light. You can also wear waterproof shoes on arrival and departure days, as you will likely be wading into shallow water.
  • Plan your arrival: Try to book the earliest possible boat trip from Koh Lanta. The afternoon sun can be very intense, and the journey to your resort can be somewhat difficult.

    • Accommodation tip: We recommend the Thapwarin Resort.

    We found the Thapwarin Resort on booking.com. It wasn't recommended to us by anyone, but the reviews and photos looked great, so we booked it. We paid around 5,000 THB per night – a bit more than we usually spend on hotels in Thailand, but absolutely justified given the location. The price at the Thapwarin can vary depending on the season and when you book, so it's always advisable to book well in advance.

    Why we loved it:

  • Beachfront location: Thapwarin is situated at the northern end of the island and offers direct access to the main beach. Our bungalow was about 100-200 meters from the shore, providing us with a small oasis surrounded by nature. The resort is known for its two palm trees that lean over the beach, creating a classic Koh Ngai photo opportunity.
  • Resort comfort in a relaxed atmosphere: The Thapwarin is officially a 3-star resort. It offers significantly more comfort than, for example, a budget bungalow, but not as many luxury amenities as a 5-star resort. The bungalows are spacious, the beds comfortable, and the food in the restaurant is first-class. Important: Be sure to book a room with air conditioning, as it can still be hot and humid at night on Koh Ngai. Some of the cheaper rooms only have fans, and in our experience, a fan is not sufficient in the Thai heat.
  • Fair price: The value for money at Thapwarin is excellent. Booking your bungalow several weeks in advance will likely secure you a good price. However, be sure to keep an eye on your restaurant bill, as it can be an unpleasant surprise when you pay. To save money on food, you can try eating modestly at the restaurant or pack some fruit and snacks in advance on Koh Lanta.

    The best things to do in Koh Ngai

    Sunbathing & Swimming

    Koh Ngai is perfect for relaxing days on the beach, and sunbathing and swimming are part of everyday life here. At low tide, there's plenty of space to spread out and soak up some vitamin D. At high tide, the water reaches right up to the resort, creating shallow pools that are perfect for swimming. We were amazed by the crystal-clear water quality in Koh Ngai, and the temperature was fantastic. It's advisable to limit sun exposure to 2-3 hours per day. Unfortunately, Cam learned this the hard way and got a nasty sunburn on our very first day on the island.

    Observing hornbills in the trees

    One of Koh Ngai's most unique features is the opportunity to spot hornbills. The island is home to the Oriental hornbill, a beautiful black and white bird with a yellow beak and a large crest. During our daily beach walks, we often spotted them hidden in the treetops and occasionally flying overhead. You don't have to venture deep into the jungle to see them, as they frequently forage for fruit and insects near the beach resorts.

    Beach walks

    Since Thapwarin is located at the northern end of the beach, we took a walk to the southern end and back almost every day. It was a great way to get some exercise, discover different viewpoints overlooking the surrounding islands, explore the amenities offered by the other resorts, and find fantastic photo opportunities. At low tide, the beach recedes significantly, providing plenty of space for walking.

    Beach bars & drinks at sunset

    We stumbled upon a small, rustic, makeshift bar on Main Beach and decided to enjoy the sunset there every evening. There was nothing but plastic chairs, tree umbrellas, cold beer, and a breathtaking view of the three iconic islands surrounding Koh Ngai. The sunsets there were truly spectacular!

    kayaking

    For those seeking a more adventurous experience on Koh Ngai, kayaking is a fantastic option. Most resorts, including Thapwarin, offer kayak rentals. At high tide, you can paddle out onto the calm waters and admire the island from the same perspective as upon arrival. You can also paddle to the island's edges and explore hidden coves and stretches of coastline.

    Snorkeling

    The coral reef off the coast of Koh Ngai is easily accessible with a short swim from the shore. While not the most colorful or vibrant reef in all of Thailand, it offers excellent snorkeling opportunities, especially given its proximity to the beach resorts. The snorkeling spots in front of the Thapwarin Resort, the Thanya Beach Resort, and the Kaimuk Thong Resort are all considered great options.

    Day trip to nearby Koh Kradan

    A day trip to Koh Kradan, named the best beach in the world by the World Beach Guide in 2023, is an absolute must. Unfortunately, all the longtail boats were fully booked when we wanted to go. It's recommended to take a day trip from Koh Ngai rather than staying overnight, as the island is very basic and has limited electricity and infrastructure. However, it offers a more beautiful coral reef, a pristine beach, and—believe it or not—even fewer visitors. If you're concerned about availability, it's best to contact your resort to book the tour or a private longtail boat before your trip.

    Beach massage

    About halfway along the main beach, you'll find a simple open-air massage parlor. Kat treated herself to a massage two or three times during our stay on Koh Ngai and highly recommends it. The sea breeze and the sound of the tide during the massage add to the relaxation.

    When should you visit Koh Ngai?

    The dry season in Koh Ngai lasts from November to April. However, to be on the safe side, we recommend visiting between December and March. Many resorts close from May to October due to rough seas and limited boat services. If you plan to travel during the main rainy season, it's best to contact the resort directly to ensure it's open and boats are available for transfers.

    Honestly, our timing in February couldn't have been better. We enjoyed brilliant blue skies, hardly any wind, and warm, calm water. If you can travel in December, January, or February, there's a good chance you'll find perfect beach conditions. The risk of rain is higher in November or April, but don't let that deter you—a few tropical downpours only add to the island's charm.

    Tips for visiting Koh Ngai

  • Bring cash/Be prepared for limited options: There are no ATMs on the island, and most transactions are cash-based (e.g., massages). However, Thapwarin accepted card payments for our restaurant bill. Withdraw some cash and buy everything you need before arriving on Koh Lanta.
  • Enjoy the peace and quiet: Koh Ngai isn't a party or adventure island. It's ideal for travelers who simply want to relax in a beautiful beach setting. We recommend a stay of at least three to four nights to truly experience the island's laid-back atmosphere. If you're looking for nightlife, we recommend Koh Phangan or Koh Phi Phi. For those seeking adventure, Koh Chang or Koh Samui are always good choices.
  • Respect the reef and wildlife: avoid stepping on or damaging coral (wear water shoes if necessary), keep a safe distance from hornbills and other birds, and behave respectfully towards nature.
  • Keep the sand out of your room: As with any beach, sand gets everywhere. Therefore, clean your bags, flip-flops, etc., before returning to your room. If you are staying at the Thapwarin, you can use the provided cups of water outside your room to clean your feet and gear.
  • Live in the moment: As travel bloggers, we took many photos during our stay on Koh Ngai, but we also consciously sought out moments to put our phones aside and simply enjoy the moment. Koh Ngai is a place where you want to shut out the outside world and fully embrace paradise!
