Koh Phra Thong is located in Khura Buri District, Phang Nga Province, along Thailand’s upper Andaman coast, not far from significant marine ecosystems such as Mu Ko Surin National Park. The island stands out from typical Thai tourist islands due to its predominantly flat terrain and diverse ecosystems, including sandy beaches, mangrove forests, wetlands, and expansive grasslands. These landscapes were formed through long-term sediment deposition and historical sea-level changes, resulting in coastal plains and sand ridges that are relatively rare among Thailand’s islands.

One of the island’s most distinctive features is its "Savannah-like Grassland," which spreads across much of the interior, particularly in the central and northern zones. The sandy soil and good drainage support the growth of grasses and small Melaleuca trees, creating a landscape of golden fields dotted with low vegetation. While often compared to African savannahs, this ecosystem is uniquely adapted to the tropical monsoon climate of Southeast Asia. Visitors typically explore these grasslands during early morning or late afternoon, when sunlight enhances the golden hues of the terrain and wildlife activity becomes more visible, including large birds and reptiles in their natural habitat.

The coastline of Koh Phra Thong, especially along its western side facing the Andaman Sea, consists of long, uninterrupted sandy beaches that remain largely undeveloped. These beaches are shaped by seasonal monsoon patterns and serve as important ecological zones, including nesting grounds for sea turtles during certain periods of the year. The absence of mass tourism infrastructure allows visitors to experience a rare sense of isolation and tranquility, making it an ideal destination for those seeking quiet beach environments and unspoiled natural scenery.

Marine ecosystems surrounding the island are also well-preserved, particularly around nearby islets such as Koh Pling, where shallow coral reefs support a variety of marine life. These areas are suitable for snorkeling, especially during calm sea conditions. Additionally, the island’s wetlands and coastal zones provide critical habitats for resident and migratory bird species, making Koh Phra Thong an important site for birdwatching and ecological research. Several rare and regionally significant bird species have been recorded in this area, highlighting its biodiversity value.

From a cultural perspective, Koh Phra Thong is home to local communities, including the Moken people, who have traditionally lived in close relationship with the sea. The island’s residents maintain a simple, sustainable lifestyle based on fishing and natural resource use. Visitors have the opportunity to observe and learn about traditional practices, community life, and environmental stewardship. This cultural dimension adds depth to the travel experience and reinforces Koh Phra Thong’s identity as a destination focused on sustainability and authentic local engagement rather than commercial tourism.
