You’re standing on Patong Beach, shoulders already a little pink from the sun, looking out at the horizon. It’s beautiful, sure. But honestly? It’s crowded. You can hear the jet skis buzzing like angry hornets and the guy next to you is playing techno on a Bluetooth speaker. You came here for that "postcard" version of Thailand, and this isn't quite it.
The good news is that the version you're looking for actually exists. It’s just not on the island of Phuket. It’s scattered across the Andaman Sea, sometimes only fifteen minutes away by longtail boat.
I’ve spent a lot of time hopping between these limestone karsts and sandy spits. People always ask, "Which one is the best?" That’s the wrong question. The real question is: "Which island won’t make me feel like I’m in a floating shopping mall?"
The Near-Shore Escapes: Low Effort, High Reward
If you only have half a day or you're traveling with kids who get cranky on long boat rides, look at the southern coast. Koh Bon is the one nobody seems to talk about, yet it’s right there. You can literally see it from Rawai Beach.
It takes about 10 or 15 minutes to get there. You hire a longtail boatman directly on the sand—don’t overthink the "booking" part, just walk up and point. It’s quiet. There are no fancy resorts, just a simple beach shack and some of the clearest water you’ll find that close to the mainland. It’s the perfect place to do absolutely nothing for three hours.
Then there’s Coral Island (Koh He).
Okay, let’s be real: Koh He is popular for a reason. On a sunny day, the water is a shade of blue that looks fake. It’s striking. But because it’s so accessible, it can get packed with day-trippers doing parasailing and banana boat rides.
Pro tip: Most people congregate at Long Beach. If you want to actually breathe, take the jungle trail over to Banana Beach. It’s half the size, much quieter, and the snorkeling right off the shore is surprisingly decent for 2026 standards.
The Racha Islands: Where the Water Gets Serious
If you’re willing to spend 30 to 45 minutes on a speedboat, head south to the Racha (or Raya) islands.
- Racha Yai: This is the "big" one. It has actual infrastructure, like The Racha resort, which is pretty high-end. The sand here is like powdered sugar. Seriously.
- Racha Noi: About 45 minutes further south from its big brother. It’s uninhabited, rocky, and a favorite for divers.
The visibility at Racha Noi is legendary. We’re talking 20 to 30 meters on a good day. If you’re lucky, and I mean really lucky, you might spot a Manta Ray. They tend to hang out around the southern tip between November and April. Even if you don't see one, the underwater granite boulders make you feel like you’re swimming through a sunken mountain range.
The Elephant in the Room: Phi Phi and Maya Bay
You can’t write about islands off Phuket Thailand without mentioning the Phi Phi islands. It’s the law, basically.
Maya Bay is iconic. Everyone knows it from The Beach. But here is what most people get wrong: they think they can just roll up at noon and have a spiritual moment. You won't. You'll have a moment with 400 other people’s selfie sticks.
In 2026, the Department of National Parks (DNP) is still very strict. You can’t swim in the actual bay anymore to protect the blacktip reef sharks—which, honestly, is a good thing. They’ve made a massive comeback. If you want to see Maya Bay without the rage, you have to take an "Early Bird" tour. These leave Phuket around 5:00 AM. It’s painful to wake up that early on vacation, but standing on that sand when the sun first hits those limestone cliffs? It’s worth the lack of sleep.
Beyond the Postcard: Phang Nga Bay
If you hate waves and getting seasick, go north into Phang Nga Bay. Because it’s a sheltered bay, the water is almost always flat. It’s not "snorkel blue"—it’s more of an emerald green because of the mangroves—but the scenery is wild.
James Bond Island (Khao Phing Kan) is the big draw here. You’ve seen the rock (Koh Tapu) that looks like a giant nail driven into the sea. It’s cool, but it’s a "take a photo and leave" kind of place.
The real magic in Phang Nga is Koh Panyee. It’s a Muslim fishing village built entirely on stilts over the water. They have a floating football pitch that is genuinely mind-blowing to see in person. Eat lunch there. The seafood is fresh, and the community is incredibly welcoming, though it’s polite to dress modestly (shoulders covered) while walking through the village.
Navigating the Logistics: Costs and Timing
Let's talk money, because things have shifted a bit recently.
A private longtail boat to Koh Bon or Coral Island will usually run you between 1,200 and 2,500 Baht depending on your negotiating skills and how long you want to stay. Speedboat day trips to the Similans or Phi Phi are much pricier, often ranging from 3,500 to 5,500 Baht per person, including lunch and national park fees.
Speaking of fees, don't forget the National Park entry. For places like Phi Phi or the Similans, it’s usually 400 Baht for adults. Keep your ticket! Sometimes it’s valid for other spots in the same park if you’re doing a multi-stop day.
Actionable Steps for Your Island Adventure
If you're planning your route right now, here is the most logical way to do it:
- Check the Season: If you're here between May and October, the Similan Islands are closed. Period. Don't let a shady street vendor tell you otherwise. Stick to the east coast islands like Koh Yao Noi or the sheltered spots in Phang Nga Bay.
- Pick Your Boat: Speedboats are fast but bumpy. If you have back issues, avoid them like the plague. Large catamarans are the "luxury" way to go—they're slower but way more stable and usually have better food.
- Go Early: I cannot stress this enough. If the tour says it leaves at 8:00 AM, find one that leaves at 6:00 AM. Being the first boat at a lagoon is the difference between a core memory and a crowded nightmare.
- Reef-Safe Sunscreen: It’s actually a requirement in Thai National Parks now. If you bring the cheap stuff that kills coral, the rangers can technically fine you. Buy a bottle of "Reef Safe" at any pharmacy in Phuket before you board.
The Andaman Sea is changing. Some reefs are recovering, some are struggling with the heat, but the sheer scale of these islands still hits you in the chest when you see them for the first time. Pick one, get on a boat, and just go.
