Pak Nam Bay, often referred to locally as "Loh Pa Nan," is situated on the northeastern coast of Koh Phi Phi Don. This bay possesses a unique geographical character, being sheltered by high limestone ridges that act as a natural barrier against seasonal winds and swells. The beach spans approximately 300 meters, featuring fine golden sand that contrasts beautifully with the translucent turquoise waters. Remarkably, Pak Nam Bay has preserved its pristine state due to limited land access, shielding it from the rapid tourism development and overcrowding experienced by more central areas like Tonsai Bay or Loh Dalum.

From a cultural perspective, Pak Nam Bay is home to a small, traditional sea gypsy (Moken) community that has lived in harmony with the sea for generations. The dwellings here remain modest and integrated into the dense coconut groves, offering the most authentic glimpse of what Koh Phi Phi looked like before the tourism boom. Visitors can observe traditional artisanal fishing techniques and the daily use of long-tail boats for transportation—a lifestyle that is becoming increasingly rare in other parts of the archipelago. The tranquility of this bay is not merely physical but cultural, representing a way of life that remains unconsumed by modern commercialization.

Regarding the marine ecosystem, Pak Nam Bay is a biodiversity hotspot. The nearshore area features seagrass beds and shallow coral reefs that remain in relatively healthy condition, providing a habitat for anemonefish, parrotfish, and occasionally juvenile blacktip reef sharks that roam the shallows during calm periods. Additionally, a small mangrove forest connected to a short canal behind the beach—the namesake of "Pak Nam" (River Mouth)—serves as a vital nursery for young marine life. This synergy of terrestrial and marine environments makes Pak Nam Bay a significant natural classroom for those interested in genuine eco-tourism and environmental conservation.

• From Tonsai Pier, the most convenient way to reach Pak Nam Bay is by hiring a local long-tail boat, which takes about 15–20 minutes. Alternatively, active travelers can hike from the Phi Phi Viewpoint through a jungle trail that leads directly down to the bay.

• Wear sturdy hiking shoes if you plan to take the jungle trail from the viewpoint.

• The best time for photography is before noon when the sunlight hits the water perfectly.

• Use a waterproof dry bag to protect your electronics while traveling by long-tail boat.

• Check the tide tables before visiting to ensure optimal conditions for swimming and snorkeling.

• Carry a basic first-aid kit since the nearest pharmacy is located back in the main village.
