There’s no shortage of luxurious resorts on Phuket, making it a memorable family holiday or romantic honeymoon destination. Discover your island bliss at gems including Kata RocksThe Nai Harn and Diamond Cliff Resort & Spa

Koh Phi Phi Don

The Phi Phi islands are a gold mine of powder-white beaches, flourishing jungle and aquamarine waters. The largest of these islands, Koh Phi Phi Don, is the perfect hideaway from the hustle and bustle of city life. One of the best things to do is spend sun-soaked days basking on postcard-perfect beaches. On the north-eastern corner of the island, roll out a towel on Ao Lo Bakao, a beach flanked by palm trees and dramatic green hills. On the west coast, make footprints on Phi Phi Don’s softest, whitest sand at Long Beach. Get here on foot via a short jungle trail from the centre of town.

When you feel like stretching your legs, brave the strenuous climb to Phi Phi Viewpoint. Armed with a bottle of water, follow the narrow, twisting path from Ton Sai Village through jungle, to the highest point on the island (the walk takes 20-30 minutes). Your efforts are rewarded with a spectacular panorama across Loh Dalum Bay.

How to get here: Koh Phi Phi Don is easily accessible via a two-hour ferry from Phuket or 90-minute ferry from Krabi. 

Koh Samui

You can’t look past Koh Samui when it comes to discovering Thailand’s best islands. This island gem is a popular tourist destination – and for good reason. Koh Samui’s laidback vibe makes it a great spot to take the family. Spend a day at tranquil Maenam Beach on the island’s north coast, where calm waters are perfect for swimming. The beach is fringed by palm trees and just beyond, you’ll find Fisherman’s Village, a pedestrian street lined with cafés and shops.

Pack your swimmers and head southeast for Na Muang Waterfalls. Surrounded by lush forest, these sister waterfalls cascade into a large waterhole – perfect for an afternoon dip. Meanwhile, at Ang Thong National Marine Park – an archipelago of 42 islands east of Koh Samui – spend a day kayaking, hiking and snorkelling.  

Foodies will rejoice at the abundance of mouthwatering dining options on Koh Samui. Fill your belly with traditional Thai dishes cooked to perfection: think massaman curry, papaya salad and mango sticky rice. You can also feast on freshly caught rock lobster at a seaside restaurant, pop into one of the many kôw gang (rice and curry) shops or order a straight-from-the-pan pad thai at a local market.

How to get here: Fly from Bangkok or Phuket to Koh Samui Airport (USM).  

Koh Lanta

Koh Lanta Old Town.

Off the coast of Krabi, discover another of Thailand’s best islands, the pristine natural wonderland of Koh Lanta. This is where you come to relax and recharge your social battery. The island is ultra-laidback, with very little traffic, long secluded beaches and jaw-dropping sunset views. The best way to explore the island is by hiring a moped and zipping along near-empty roads, bouncing between beaches, exploring Koh Lanta National Park and visiting Koh Lanta Old Town.

Head out on the water for the day to island hop the tiny Trang archipelago, a nearby cluster of limestone islands. Here you can swim through the enchanting Emerald Cave and discover a secret beach. If you’re looking for some of the best snorkel spots in the area, head to Koh Rok. Submerge yourself in bright turquoise water and keep on the lookout for vibrant parrotfish, titan triggerfish and clownfish.

Koh Phangan

Party-goers and full moon revellers might be familiar with one of Thailand’s best islands, Koh Phangan. This island paradise is home to a boisterous monthly Full Moon Party, a night-long celebration tied to the lunar calendar. But there’s so much more to this dreamy island than a night of merriment. Outside of party season, hire a scooter and uncover a haven of secluded coves, untouched wilderness, waterfalls and sacred temples. Koh Phangan is quieter than many other islands, making it a relaxing escape from the crowds.
