The Koh Hong Islands, located in Krabi, Thailand, are famous for their breathtaking natural beauty, crystal-clear turquoise waters, and dramatic limestone cliffs rising from the Andaman Sea. These islands are especially known for their hidden emerald lagoon, accessible through a narrow entrance, which creates a peaceful and almost surreal atmosphere.

Visitors love Koh Hong for its unspoiled scenery, calm waters ideal for swimming and snorkeling, and the feeling of escaping to a true tropical paradise far from crowds. The archipelago is made up of Koh Hong (the main island), Koh Lao Lading (Paradise Island), Koh Pakbia, and Koh Daeng — all known for their limestone cliffs, white-sand beaches, and crystal-clear waters.

What You’ll Find

White-sand beaches and shallow, crystal-clear waters make Koh Hong one of the most inviting swimming destinations along the Andaman Coast, calm enough for all ages and perfect for long, unhurried afternoons in the sea.

The iconic emerald lagoon, surrounded on all sides by towering limestone cliffs, is the heart of Koh Hong — a hidden world accessible only through a narrow gap in the rock, where the water glows green and the silence is complete.

Excellent spots for swimming and snorkeling surround the islands, with coral reefs just below the surface and a variety of marine life including reef fish, sea turtles, and colorful corals in the clear Andaman waters.

Panoramic viewpoints offer stunning sea and island views across the archipelago — a landscape of limestone peaks, turquoise bays, and jungle-covered slopes that stretches all the way to the horizon.

A quiet, natural environment sets Koh Hong apart from busier island destinations. The absence of permanent settlements keeps the islands pristine and the atmosphere genuinely peaceful, perfect for relaxation and reconnecting with nature.
