Koh Haa (also spelled Koh Haa) is a stunning archipelago consisting of five small islands located in the Andaman Sea, part of Krabi Province, Thailand. Its name translates to “Five Islands” in Thai, and it’s renowned for its crystal-clear waters, vibrant coral reefs, and diverse marine life, making it a paradise for snorkelers and scuba divers alike.

The islands are part of the Mu Koh Lanta National Park, ensuring the preservation of their natural beauty and ecological diversity. The marine environment around Koh Haa is home to a wide variety of sea creatures, including colorful fish, sea turtles, moray eels, and even the occasional whale shark, providing an unforgettable underwater experience.

One of the most famous dive sites within the Koh Haa archipelago is the “Chimney,” a vertical swim-through that divers can enter at about 5 meters and exit at 16 meters, emerging into a stunning, open, underwater chamber. Another highlight is the “Lagoon,” a shallow, sheltered area with crystal-clear water, perfect for snorkeling and beginner divers. The lagoon’s sandy bottom and scattered coral make it an ideal environment for learning diving skills in a breathtaking setting.

Apart from the underwater attractions, Koh Haa’s islands feature spectacular limestone cliffs, pristine beaches, and emerald-green waters, offering a picturesque landscape both above and below the water. The islands remain relatively untouched by development, providing a serene and natural escape from the more crowded tourist destinations.

Koh Haa is accessible by boat, with day trips commonly departing from Koh Lanta, Phuket, and Krabi. These excursions typically include opportunities for snorkeling, diving, and simply relaxing on the islands’ beautiful beaches. Due to its protected status, visitors are encouraged to follow eco-friendly practices to help preserve this exquisite natural environment for future generations.

Whether you’re an experienced diver looking for new challenges, a snorkeling enthusiast eager to explore vibrant coral gardens, or someone who simply wants to enjoy untouched natural beauty, Koh Haa offers a tranquil and mesmerizing escape into nature’s wonders.
