The park is officially recognized as a marine nesting habitat for four species of sea turtles.
Ton Phrai waterfall remains active throughout the year, fed by the high-elevation Khao Lampi mountain range.
The park protects rare coastal vegetation, including the distinct beach morning glory and casuarina pine trees.
The sand at Hat Thai Mueang is specifically protected to maintain ideal incubation temperatures for sea turtle eggs.
A significant portion of the park is designated as a wetland area of environmental importance.
Khao Lampi–Hat Thai Mueang National Park features a diverse ecosystem spanning the mountainous Khao Lampi range and the protected coastline of Hat Thai Mueang beach. The park is a primary nesting site for green turtles, leatherback turtles, and olive ridley turtles that lay eggs on the beach between November and February. The inland section contains the Ton Phrai and Lam Ru waterfalls, both accessible via forest hiking trails. The coastal region is characterized by an expansive sandy shoreline stretching for over 13 kilometers. The park serves as a vital mangrove conservation zone protecting unique coastal flora and fauna. Visitors can explore nature trails that wind through primary lowland rainforests. It is one of the few remaining coastal environments in the region preserved from heavy tourism infrastructure. The park headquarters provides information on local marine life and conservation efforts. Wildlife enthusiasts frequently spot macaques, langurs, and various endemic bird species within the inland forest areas.

Bring insect repellent, as the rainforest trails are prone to mosquitoes.
Check local conservation alerts before visiting to ensure turtle nesting zones remain open to the public.
Wear sturdy footwear with good grip if planning to hike to the Ton Phrai waterfall.
Do not walk on the beach at night during nesting season, as light pollution disorients female turtles and hatchlings.
Some hiking trails or beach segments may be seasonally restricted during peak sea turtle nesting months; check with the park office upon arrival.
Maintain silence near turtle nesting zones, use flashless photography only, and strictly follow 'leave no trace' principles.
