Ko Ngai

Ko Ngai is a small forested island in the Andaman Sea off the coast of southern Thailand, administratively linked to Ko Lanta District in Krabi Province and geographically between Krabi and Trang. Part of Mu Ko Lanta National Park, it is known for clear turquoise water, white sandy beaches and fringing coral reefs. The island has no roads or private vehicles and is accessed only by boat, with low-density resorts along its eastern coast.

Visitors can expect a quiet, low-development island with long white-sand beaches on the east coast, rocky coastline and viewpoints on the west, and clear shallow water with coral reefs close to shore. Accommodation consists of small resorts and bungalows. Areas to explore include the main beaches, snorkeling spots along the eastern and southern reefs, and short forest trails. No roads, cars or large town center; movement is on foot along beaches and paths.

Ko Ngai was traditionally used by local fishing communities and later incorporated into Mu Ko Lanta National Park, established in 1990 to protect islands and marine areas in Krabi and Trang provinces. Tourism development began in the 1990s with small resorts, maintaining low-density development.
