Thailand is world-famous for its iconic beach destinations like Phuket and Koh Samui, but beyond the spotlight lies a collection of untouched islands where time slows down and nature takes center stage. If you’re seeking true serenity and soul-refreshing scenery, these five lesser-known islands in the Andaman Sea are calling your name.
Koh Mook
Location: Andaman Sea, Trang Province
Best known for the awe-inspiring Emerald Cave (Tham Morakot), Koh Mook blends natural wonder with cultural charm. A swim through a dark tunnel leads you to a hidden lagoon surrounded by towering cliffs. Beyond the cave, expect quiet beaches, fishing village life, and sunset views that will stay with you forever.

Koh Ngai
Location: Andaman Sea, Krabi Province
Just a short boat ride from Koh Mook, Koh Ngai is a peaceful escape with powdery white sand and calm turquoise waters. The island is small, walkable, and entirely car-free, making it a favorite for honeymooners, snorkelers, and anyone looking to disconnect in nature.

Koh Laoliang
Location: Petra Islands, Trang Province
Raw, rugged, and remote, Koh Laoliang is where digital detox dreams come true. With dramatic limestone cliffs perfect for rock climbing, tented eco-camps, and coral-rich snorkeling spots, it offers a rare, off-the-grid experience inside a national park. No roads, no Wi-Fi—just pure connection with nature.

Koh Bulon
Location: Andaman Sea, Satun Province
Often overlooked, Koh Bulon is a small island gem with calm beaches and an authentic village atmosphere. Friendly locals, simple bungalows, and clear waters filled with fish make it a hidden paradise for those who seek peace and authenticity. You’ll likely spend your days barefoot and blissed out.

Koh Tarutao
Location: Tarutao National Marine Park, Satun Province
Koh Tarutao is steeped in history—it was once a penal colony—but today it’s part of a protected marine park known for its untamed beauty. Jungle trails, wildlife spotting, and miles of undeveloped beaches make this island a sanctuary for adventurers and nature lovers.
