Doi Phu Nang National Park

Doi Phu Nang National Park protects roughly 860 square kilometres of mountain forest across three Phayao districts — Chiang Muan, Pong, and Dok Khamtai — and holds Thailand’s largest known wild population of green peafowl. Gazetted in June 2012 as the country’s 127th national park, it draws a fraction of the visitors that Doi Inthanon or Khao Yai see, which means trails you’ll often have entirely to yourself.

The peafowl are the real reason to make the drive. Green peafowl (nok yoong, ไก่ฟ้า in some local usage) are shyer and rarer than their Indian cousins seen in temple grounds elsewhere in Thailand — spotting one in the wild, tail fanned in a forest clearing at dawn, is a genuine wildlife moment rather than a captive-bird photo op. Beyond the peafowl, the park’s deciduous forest holds teak stands, bamboo groves, and waterfalls fed by the Doi Phu Nang range, with trails ranging from short interpretive loops near headquarters to longer routes climbing toward mountain viewpoints over the Chiang Muan valley.

Insider Tip: Ask rangers at the visitor centre which trail has had recent peafowl sightings — the birds move between feeding areas by season, and staff track this daily even though it’s not posted anywhere online.

Morning fog rolling through the valleys below the peaks is common from November through February, when cool-season conditions also make the steeper trail sections far more comfortable than the hot months. Rainy season (June-October) greens up the forest dramatically but turns some paths slippery and can wash out the drive in. Bird calls and wind through bamboo are the only real sounds most of the day — this isn’t a park with food stalls or crowds at the entrance gate.

Watch out: There’s no mobile signal on most of the interior trails, and the ranger station doesn’t always have someone on duty outside office hours. Tell someone your planned route and expected return time before setting off on longer hikes.

Basic camping is available near the park office for overnight stays — bring your own tent, sleeping gear, and food, as there are no on-site rental shops. Access is by private vehicle only; there’s no scheduled public transport to the entrance, so factor in a rental car or arranged driver from Phayao town, about an hour away on rural roads. Pack sturdy hiking shoes, insect repellent, and enough water for the day, since refill points inside the park are limited.
