The 15 Most Visited Islands in Thailand
Here’s the island ranking you’ve been waiting for. Some are perfect for hammock lounging, others for diving with sharks (which we can tell you a lot about), and some are made for partying like there’s no tomorrow. The hard part is picking just a few, because honestly—they all have their magic.
1. Phuket
Thailand’s largest and most famous island. It has everything: stunning beaches, buzzing nightlife, street markets, and hidden temples. Phuket is a vibrant mix of traditional and modern.
How to get there:
Direct flights from Bangkok or even from abroad. Also reachable by bus or ferry from nearby islands.
2. Koh Phi Phi
Small but mighty. This island shot to fame thanks to The Beach movie, and has been drawing crowds ever since (so much so that Maya Bay had to be restricted). Think postcard-perfect waters, mysterious caves, and wild beach parties. Great for young, free-spirited travelers.
How to get there
Ferry from Phuket or Krabi, several times a day.
3. Koh Samui
Perfect for those seeking a touch of luxury without losing the island vibe. It has high-end resorts, dreamy spas, calm beaches, and a lively atmosphere. Koh Samui strikes the perfect balance.
How to get there:
Direct flight from Bangkok or ferry from Surat Thani.
4. Koh Phangan
Famous for its Full Moon Parties, but also home to quiet, peaceful corners. The north of the island has almost empty beaches and yoga retreats. A double-personality island for both party animals and zen souls.
How to get there:
Ferry from Koh Samui or Donsak.
5. Koh Tao
A diver’s and snorkeler’s paradise, with crystal-clear waters and incredible marine life. It’s also one of the cheapest places in the world to get your scuba certification. Ideal for ocean adventurers.
How to get there:
Ferry from Koh Phangan or Chumphon.
6. Koh Lipe
A gem in Thailand’s far south, near the Malaysian border. The water is like a natural pool, and the sand is so fine it crunches under your feet. Perfect for slow travel and total relaxation.
How to get there:
Ferry from Pak Bara or Langkawi (Malaysia).
7. Koh Lanta
Peaceful and expansive—great for exploring by motorbike at your own pace. Long beaches, chilled vibes, and very family-friendly. A homey island you’ll want to stay on.
How to get there:
Ferry from Krabi or Phuket.
8. Koh Chang
One of the largest islands, with dense jungle, hidden waterfalls, and uncrowded beaches. Despite its size, it’s still less touristy than others. 100% adventure and nature.
How to get there:
Ferry from Trat (buses available from Bangkok).
9. Koh Samet
Just a few hours from Bangkok, this is a favorite weekend escape for locals. Small, easy to navigate, and full of charming beaches. Great for a quick sand-and-sea getaway.
How to get there:
Bus from Bangkok, then ferry from Ban Phe.
10. Koh Yao Noi
One of Thailand’s most tranquil islands. No crowds or crazy parties—just rice fields, fishermen, and jaw-dropping views of limestone cliffs. Ideal for true disconnection.
How to get there:
Ferry from Phuket or Krabi.
11. Koh Yao Yai
Slightly larger than its sister Koh Yao Noi, but just as authentic. Virgin beaches and a slow rhythm of life. A hidden gem for those seeking calm.
How to get there:
Ferry from Phuket or Krabi.
12. Koh Mak
A lesser-known island still off the tourist radar. Time slows down here—no big hotels, no traffic, no stress. Just you, the sea, and the sound of palm trees swaying.
How to get there:
Ferry from Koh Chang or Trat.
13. Koh Kut (Koh Kood)
Untouched nature, cool waterfalls, and empty beaches. One of Thailand’s most pristine and least developed islands. A dream for those who hate crowds.
How to get there:
Ferry from Trat or Koh Chang.
14. Koh Nang Yuan
A trio of islets connected by a thin stretch of white sand. Tiny and usually visited on a day trip from Koh Tao—but the snorkeling here is out of this world. Pure postcard stuff.
How to get there:
Taxi boat from Koh Tao.
15. Similan Islands
A protected archipelago with some of the best diving spots in the country. Only open in season (October to May), but 100% worth it if you love scuba diving.
How to get there:
Boat tours from Khao Lak or Phuket.
