Phu Ruea National Park (Loei)

Phu Ruea’s summit area often posts some of Thailand’s lowest seasonal temperatures, and the park’s campground near headquarters is a favorite for easy-access cold-weather camping. Expect 2–10°C on midwinter nights, with the occasional frost on vehicles and grasses during strong cold spells. Clear, dry air after a front can create inky-black skies and brilliant constellations.

The park usually rents tents, mats, and blankets near HQ. Weekends and holidays can be busy, so consider reserving accommodations where available and arrive early for prime, level pitches. Standard park permits are paid at the gate, and some peak periods may use local quota management. Pack a proper winter-rated sleeping bag, thermal layers, and a windproof jacket, as open slopes can feel significantly colder than the thermometer suggests.
