‘Sabai sabai’. This simple Thai phrase translates as being totally relaxed. And when you’re on holiday in Thailand being sabai sabai is something you’ll quickly become accustomed to. That chilled-out feeling when work is the last thought on your mind and the biggest dilemma of the day is which cocktail to order next as you sit by the pool. There aren’t many better ways to get in the sabai sabai zone than heading for the beach on one of the stress-free Thai islands. But which is the best Thai island to visit? Everybody will have their own opinion of what makes the perfect relaxing Thai island getaway. Some will opt for an island with bamboo huts and simple seclusion, others may prefer boutique hotels and luxury pampering. In the final analysis, the ideal Thai island boils down to your own personal choice and style of travel. World famous resort islands like Ko Samui and Phuket are both excellent destinations to visit, but Thailand is also home to a myriad of smaller tropical idylls waiting to tempt you. Take a look at this selection of islands in the Andaman Sea which will have you feeling sabai sabai as soon as you arrive.

Ko Lanta

Ko Lanta is an island at ease with itself. This is a destination that welcomes tourists, but never feels overwhelmed by them. Ko Lanta has retained a strong sense of community amongst the local population and the relaxed pace of life here is infectious. Although the island is already known to tourists, Ko Lanta doesn’t see anything like the same number of visitor numbers as nearby Phuket or Krabi. This has enabled Ko Lanta to retain its charm and low-key atmosphere. Whether you are a solo traveller looking for adventure, a couple in search of a romantic retreat or a family looking for fun by the beach, Ko Lanta is an excellent all-round choice for your Thai holiday.
Suggested hotels:
Layana Resort & Spa
Pimalai Resort & Spa
Crown Lanta Resort & Spa
What to see and do on Ko Lanta
Ko Lanta is actually two islands; Koh Lanta Noi (‘i’ = small) and Ko Lanta Yai (‘’ = big). All of the best beaches, hotels and tourist facilities are found on Lanta Yai and all along the west coast there are plenty of stretches of sand to choose from. The further south you go the quieter they tend to be, but even on the most popular beaches like Long Beach they seldom seem crowded and the atmosphere is peaceful. Beneath the waves, Ko Lanta offers up some excellent snorkelling and diving opportunities. With frequent boat connections, Ko Lanta also makes a good jumping off point if you are travelling to or from Krabi, Phi Phi or Phuket. If you feel like doing something more active away from the comfort of your sun-lounger, Ko Lanta has a number of options. Take a tour of Thung Yee Pheng Mangrove Forest or explore the natural beauty of Mu Ko Lanta National Park. Make the walk up to the viewpoint by the old lighthouse and enjoy the gorgeous views over the Andaman. If your taste buds have been tickled by tasty Thai food, learn how to create your own massaman curry and other signature dishes at Time for Lime cooking school. The people behind Time for Lime have also established Lanta Animal Welfare, an initiative which helps take care of cats and dogs on the island. For a slice of local life pay a visit to Lanta Old Town on the east of the island, but please dress more politely than you would for the beach and respect the cultural sensitivities of local Thai Muslims and Buddhists. Ban Saladan in the north of the island is where most of the ferries arrive and serves as the main commercial centre for Ko Lanta. You’ll find atmospheric seafood restaurants here alongside some excellent cafes and budget guest-houses.
Ko Yao Noi and Ko Yao Yai

The twin islands of Ko Yao Noi and Ko Yao Yai sit in an enviable location with glorious views of the magnificent limestone karsts of Phang Nga Bay. The location and tranquility of the islands make them ideal if you want to explore nature. Hire a bicycle and ride along traffic-free roads past rubber-tree plantations and local villages. Jump in a kayak and paddle around Ko Yao Noi pausing only to admire the scenery and relax on hidden beaches. But visitors to Ko Yao Noi and Ko Yao Yai need to be careful; the charm of these islands can be addictive. You have been warned!
Suggested hotels:
Cape Kudu
Paradise Ko Yao
Santhiya Ko Yao Yai
Six Senses Yao Noi
Ko Yao Noi and Ko Yao Yai
Ko Lipe

Given the outstanding natural beauty of Ko Lipe it’s perhaps a surprise that it remained off the main tourist trail for so long. The main reason for that may have been the isolated location the island enjoys in the southern Andaman Sea. Improved transport connections has resulted in a rise in development and tourism in recent years. Although Ko Lipe may no longer be the untouched paradise it once was, it remains a beautiful island to visit.
Suggested hotels:
Mountain Resort
Sawan Resort
Serendipity Resort
What to see and do on Ko Lipe
The compact size of Ko Lipe makes it an easy task to walk between the three main beaches; Pattaya Beach, Sunrise Beach and Sunset Beach. They are all attractive stretches of sand and leading off Pattaya Beach you’ll find a paved road known as ‘Walking Street’ lined with restaurants and street stalls. You’ll also find plenty of tour offices here where you can book diving or snorkelling trips to the uninhabited islands of Tarutao National Marine Park. Be sure to make the short hop by longtail boat across the aquamarine waters to neighbouring Ko Adang. The beaches here are stunning, but drag yourself away from them and make the walk up to the viewpoint. It will take around 30 minutes to get to the top and you’ll be hot and sweaty when you get there. But the reward for your workout are glorious views looking down on Ko Lipe. You’ll just make out the faint hum of distant longtail boats and if you avert your eyes skywards you are likely to notice sea eagles effortlessly gliding in the thermals.
Ko Ngai

It’s no surprise that lovely Ko Ngai (also known as Ko Hai) is popular with couples, but don’t let that put you off if you’re by yourself and looking for somewhere to relax and simply get away from it all. Geographically, this diminutive island is close to Trang province and is often included as one of the Trang Islands although it is actually part of Krabi province.
Suggested hotels:
Coco Cottage
Ko Ngai Cliff Beach
Trang Islands
Trang town is the gateway to dozens of islands strung out in the Andaman Sea. Collectively they are known as the Trang Islands. These islands are perfect for anybody seeking to get away from the crowds. You won’t find nightlife or fine dining here, but you will find stunning beaches, quiet seclusion and amazing views.
Ko Kradan

With its soft sandy beaches and warm aquamarine waters, Ko Kradan lives up to its romantic reputation. In previous years this bijou tropical island has been one of the locations for the annual Trang Underwater Wedding Ceremony
Suggested hotels:
Reef Resort
The Seven Seas Resort
Ko Mook

With good boat connections to the mainland and other islands in the region, family-friendly Ko Mook is an excellent base to explore the Trang Islands. Ko Mook is home to the famous Emerald Cave in addition to some lovely beaches. This is a working island too with rubber-tree plantations and fishing providing important sources of income for the local community.
Suggested hotels:
Ko Mook Sivalai Beach Resort
Mook Lamai
Ko Laoliang, Ko Libong and Ko Sukorn

If you want luxury and all mod-cons, this trio of islands isn’t for you. But if you want to connect with nature these islands are rewarding destinations to visit. Ko Laoliang is a great base for anybody interested in rock climbing, snorkelling and kayaking. Similarly, Ko Libong is ideal for snorkelling and although it’s one of the largest Trang islands it’s also one of the least developed. Over on Ko Sukorn you’ll find a different atmosphere to the other Trang Islands. Because it lacks the stunning beaches and scenery of the other islands few tourist make it here. Ko Sukorn is very much a working island where fishermen and rubber plantations outnumber the tourists, but you will be made welcome here and if you hire a bicycle and ride around Ko Sukorn there will be times when you feel like you have the island all to yourself.
Suggested hotels:
Laoliang Resort (Ko Laoliang)
Libong Relax Beach Resort (Ko Libong)
Yataa Spa & Resort (Ko Sukorn)
