Ko Ngai, also known as Koh Hai, is a serene island paradise in the Krabi Province of Thailand, located in the Andaman Sea. This small island is part of the Trang Archipelago and falls under the Hat Chao Mai National Park's jurisdiction, though it is more easily accessible from the Krabi mainland. Known for its crystal-clear waters, white sandy beaches, and abundant marine life, Ko Ngai is a popular destination for snorkeling, diving, and relaxing by the sea. With a landscape dominated by a lush tropical forest, the island offers picturesque views and a tranquil getaway from the hustle and bustle of more crowded tourist spots. Accommodations on the island range from modest bungalows to upscale resorts, catering to a variety of travelers. Though it lacks major infrastructure and is relatively undeveloped, Ko Ngai presents an idyllic setting for a peaceful retreat. Visitors can take long-tail boats to explore nearby islands or simply enjoy the local cuisine at beachfront restaurants while soaking in the sunsets over the horizon.
