Phu Hin Rong Kla National Park (Phitsanulok/Phetchabun)

Known for otherworldly rock gardens like Lan Hin Pum and dramatic cliffs, Phu Hin Rong Kla also delivers crisp nights and clear stars. The main campground near headquarters typically sits in the 8–14°C range during December–January, with cooler readings on exposed viewpoints. The park’s elevation and distance from big-city glow make it a solid choice for astrophotography.

Gear rentals, including tents and sleeping bags, are generally available at HQ. You’ll pay standard entry permits at the gate. Roads are steep and winding, so arrive well before dark and check any time restrictions or seasonal notices. For safety and conservation, stargaze from designated areas around HQ rather than cliff edges, and bring extra insulation if you plan to linger for Milky Way shots later in the season.
