Thung Salaeng Luang National Park (Phitsanulok/Phetchabun)

Best known for its savannahs and morning mists, Thung Salaeng Luang offers big-sky camping at Nong Mae Na and other designated sites. Expect cool-season lows of roughly 10–16°C, dipping cooler during strong high-pressure systems. The open grasslands and sparse light sources create excellent stargazing on moonless nights.

Basic gear rentals are typically available at or via headquarters, but remote zones and seasonal track closures mean plans can change. Some savannah routes require 4WD and ranger permission or escort, so check conditions and rules at HQ before you commit. Standard permits are paid at entrance stations. For comfort, pitch slightly away from communal lights, carry a warm sleeping bag, and pack an extra groundsheet to guard against dew in open meadows.
