Koh Lipe, Koh Kradan, and Koh Mook are the three best islands in southern Thailand\’s Andaman corridor — and they\’re all reachable from Malaysia. Each one has a distinct character. Choosing between them depends on what kind of trip you want. This guide breaks down the honest differences so you can decide.

Koh Lipe: The Most Developed of the Three
Koh Lipe is Thailand\’s southernmost island, sitting just 4km from the Malaysian maritime border. It\’s the most visited of the three — and the most developed. Walking Street runs through the center of the island with restaurants, bars, dive shops, and guesthouses. There\’s genuine nightlife here, which neither Kradan nor Mook can offer.
Beaches
Koh Lipe has three distinct beaches. Sunrise Beach on the east coast is the standout — long, white sand with clear water, and the North Point spur offers some of the best snorkeling on the island. Pattaya Beach on the south is the most developed, with beach bars and sunloungers. Sunset Beach on the west is quieter with beautiful evening light.
Who Should Choose Koh Lipe
- Travelers who want beaches AND some social life
- Divers — Lipe has several good dive operators
- Island hoppers — Lipe is the hub for boats to Langkawi, Koh Lanta, and the Trang islands
- Anyone coming from or going to Malaysia via Langkawi
Who Should Avoid Koh Lipe
- Travelers seeking real isolation — Lipe gets busy in peak season
- Strict budget travelers — prices are higher than Koh Mook

Koh Kradan: The Most Beautiful Beach
Koh Kradan is tiny, car-free, and feels like a real-life postcard. It has fewer than 10 resorts on the entire island — which means no crowds, no noise, and no development beyond the beach. Snorkeling directly from the shore is excellent, and the main beach (Koh Kradan Beach) is genuinely one of the finest stretches of sand in Thailand.
The Catch
Koh Kradan has few tourists and fantastic beaches but is very expensive — both for food and accommodation. Because there are so few resorts, prices don\’t drop even in shoulder season. It\’s also harder to reach than Lipe — you must go via Trang\’s piers with no shortcut from Malaysia.
Who Should Choose Koh Kradan
- Couples looking for a romantic, exclusive feel
- Snorkelers — the reef directly off the beach is excellent
- Travelers who want to completely switch off — no nightlife, minimal infrastructure
- Anyone willing to pay more for genuine quiet
Who Should Avoid Koh Kradan
- Budget travelers — it\’s the most expensive of the three
- Anyone traveling in low season — ferry access is limited May to October
- Travelers who want restaurants, bars, or anything to do after dark

Koh Mook: The Sweet Spot
Koh Mook is the sweet spot — excellent beaches, lots to do, and more tourists than Kradan but not too many. It\’s the most affordable of the three, has a genuine local community, and is home to the Emerald Cave (Tham Morakot) — a sea cave you swim through in darkness to reach a hidden lagoon. That alone makes it worth visiting.
Beaches
Charlie Beach on Koh Mook\’s west coast is the main beach — soft white sand, palm trees, calm water. It\’s not as dramatic as Koh Kradan\’s main beach, but it\’s genuinely beautiful and less crowded than anything on Koh Lipe in peak season. The north and east coasts are rockier and less developed.
The Emerald Cave
Tham Morakot is Koh Mook\’s defining attraction — a 80-meter sea cave accessible only by swimming (or longtail boat entry), emerging into a hidden beach enclosed by towering cliffs. It\’s only accessible at low tide and in calm weather. Most resorts offer guided trips. There\’s nothing like it on either Koh Lipe or Koh Kradan.
Who Should Choose Koh Mook
- Budget travelers — most affordable accommodation and food of the three
- Travelers who want a unique experience (Emerald Cave)
- Island hoppers — Koh Mook is close to both Koh Kradan and Koh Ngai
- Anyone who wants quiet without the high price tag of Kradan
Who Should Avoid Koh Mook
- Travelers who prioritize beach quality above all — Kradan and Lipe have better sand
- Anyone who needs an ATM — there\’s none on the island, bring cash
