The Adang-Rawi Archipelago, a primary component of the Tarutao National Marine Park in Satun Province, represents one of the most biodiverse marine environments in the southern Andaman Sea. Koh Adang, spanning approximately 30 square kilometers, is characterized by its rugged, mountainous terrain covered in lush primary rain forests. This dense vegetation serves as a crucial watershed, feeding several permanent freshwater springs and waterfalls, such as the Pirate Waterfall—a site historically utilized by maritime marauders as a strategic freshwater supply. The island's most iconic landmark, "Chado Cliff," once served as a strategic lookout point for pirates monitoring trade routes; today, it offers a challenging trek to three distinct viewpoints, with the highest summit providing a breathtaking panoramic vista of the neighboring Koh Lipe encircled by turquoise waters.

In contrast, the nearby Koh Rawi offers a different topographical experience, featuring more extensive and accessible stretches of coastline. Its crown jewel is "Hat Sai Khao" (White Sand Beach), famous for its exceptionally fine, brilliant white sand composed of naturally weathered coral and shells. The surrounding waters maintain extraordinary clarity, allowing for high visibility of the vibrant shallow-water reefs directly from the surface. The island's interior and beach fringes, shaded by ancient Malabar almond and Sea Balsam trees, are thriving habitats for local wildlife, including Oriental Pied Hornbills, macaques, and Brahminy Kites, which are frequently sighted by visitors near the National Park protection station.

The marine ecosystems surrounding Adang and Rawi are of international ecological significance, hosting a vast array of hard and soft corals, sea fans, and anemones that provide sanctuary for diverse reef fish populations, including various species of anemonefish. This area functions as a vital ecological corridor between Thai and Malaysian waters. Consequently, tourism management here adheres to strict conservation protocols, including seasonal closures during the monsoon period to facilitate natural regeneration. This commitment to preservation ensures that the archipelago remains one of the few places in the region where the primordial beauty of the Andaman's natural landscape is preserved in its near-original state.

• Take a speedboat from Pak Bara Pier in Satun to Koh Lipe (approx. 1.5 - 2 hours). From Koh Lipe, you can hire a local long-tail boat to reach Koh Adang (10-15 minutes) or visit both islands as part of a standard inner or outer zone snorkeling tour.

• Visit during calm sea season (November–April) for the clearest water and best visibility

• Wear proper sneakers if hiking to Chado Cliff on Koh Adang, as the trail is steep

• Bring your own snorkeling gear for convenience and cost savings

• Carry drinking water and essentials, as facilities are limited, especially on Koh Rawi
