Phuket is a launchpad to some of Thailand’s most spectacular islands. Jump on a longtail or speedboat and within an hour you’re drifting past limestone cliffs, diving coral reefs, or parked under a palm with a mango shake in hand. Some spots are big-ticket famous, and others feel like a local tip. Whether you’ve got one spare day, a whole week, or a year to fill, these island escapes are easy to reach and hard to forget.

Best for: Cinematic views and snorkel-happy types

Just 45 minutes by speedboat, the Phi Phi Islands are what most people picture when they think “Thai island paradise”. Maya Bay (yes, that one from The Beach) has re-opened with limited numbers, and snorkelling here still delivers: reef fish, coral gardens, and the odd turtle. It’s buzzy, beautiful, and well worth the early wake-up.

Things to do on the Phi Phi islands:

Best for: Divers and clear-water chasers

Further out (around 90 minutes by boat), but absolutely worth it if you’re into underwater adventures. The Similan Islands are part of a national park, open from mid-October to mid-May, and famous for visibility that feels unreal — like floating through an aquarium.

Things to do:

Best for: Kayakers and movie buffs

A dramatic spike of limestone rising from Phang Nga Bay, this one shot to fame in The Man with the Golden Gun. Yes, it’s touristy — but the scenery makes it worth the buzz. Go early, go by kayak, and you’ll glide through hidden lagoons and sea caves.

Things to do:

Best for: Families and beach-first daytrippers

Only 15 minutes from Phuket, Coral Island is the fast track to palm trees and water sports. Its calm bays and decent snorkelling make it great for kids and casual swimmers. You can rent a beach chair, grab a coconut, and not overthink a thing.

Things to do:

Best for: Low-key snorkelling and clear water

Racha Yai (the bigger of the two) is about 12 km south of Phuket and a solid pick for those who want swimmable beaches without the crowds. It’s got blindingly white sand, clean reefs, and an easygoing pace.

Things to do:

Best for: Culture lovers and quiet types

Bigger, slower, and closer to the mainland side of Phang Nga Bay, Koh Yao Yai is perfect for daytrippers who don’t need a bucket bar to feel the vibe. Think local fishing villages, quiet roads for scootering, and beaches with more birds than people.

Things to do:

Best for: Nature and slow mornings

The quieter sibling of Yao Yai, Koh Yao Noi is green, grounded and ridiculously pretty. It’s popular with artists and yoga travellers but still hasn’t tipped into overdone. Pack a book, rent a scooter, and go beach to beach with zero agenda.
