Nam Nao National Park

This section is being updated and will be available shortly.

Nam Nao National Park spreads across high, cool plateau country on the border of Phetchabun and Chaiyaphum provinces, its name meaning cold water. One of Thailand's earlier national parks, it protects extensive pine and evergreen forests known for wild elephants, gibbons, misty mornings and some of the region's chilliest camping nights.

Nam Nao offers genuine wilderness with easy access, straddling the main highway between Lom Sak and Chum Phae. Its pine forests, resident elephants and cold-season dawns feel worlds away from tropical Thailand, and its trails and campgrounds suit travellers who want quiet nature over crowds.

Highlights include walking trails through fragrant pine stands, dawn mist at the campground meadows, wildlife such as elephants, gibbons and abundant birdlife, and panoramic viewpoints over forested ridges. Caves and small waterfalls within the park round out longer visits.

Hike marked trails through pine and dipterocarp forest, watch for gibbons at first light, camp under tall trees, visit viewpoints and caves, and birdwatch along the quiet park roads. Listening for the dawn chorus while mist drifts through the pines is the signature Nam Nao experience.

The pine forest trails near headquarters are the essential experience, along with the main viewpoints over the plateau and the campground meadows at dawn. Wildlife sightings, from hornbills to elephants crossing the highway at night, are unforgettable when luck allows.

Quieter trails away from headquarters see few walkers, and patient visitors may find gibbon families or rare birds without another person around. Cold-season nights reward campers with brilliant stars, and the park's caves attract far fewer visitors than its forests.

The park's remoteness once sheltered communist insurgent camps, part of the same history commemorated across Phetchabun's highlands. Nearby communities live from farming and increasingly from park-related services, and chatting with rangers offers insight into conservation work in one of Thailand's older protected areas.

This is a premier nature destination, protecting high-elevation pine savanna and moist evergreen forest rich in mammals and birds. Trails range from short interpretive walks to longer forest hikes, and the cool climate makes walking pleasant year-round by Thai standards.

Families comfortable with basic camping find Nam Nao rewarding, with safe, well-marked short trails, open meadows and the excitement of listening for wildlife. Facilities are simple, so the park suits school-age children better than infants, and night temperatures demand warm sleeping gear in the cool season.

Nightlife means campfires, star-filled skies and the sounds of the forest, with elephants occasionally heard in the distance. The park is dark and quiet after early evening, which is precisely its appeal.

Photographers favour dawn mist among the pines, golden light on the campground meadows, wildlife along the quieter roads and starscapes on clear cold-season nights. A telephoto lens for birds and gibbons and a tripod for low light both earn their place in the bag.

Nam Nao was declared a national park in 1972, among the earlier entries in Thailand's protected-area system. Its highlands saw insurgent activity during the Cold War era, and the completion of the highway through the park later opened its forests to easy visitation while conservation rules kept them intact.

Surrounding districts of Phetchabun and Chaiyaphum are agricultural, with markets and temples in towns such as Lom Sak reflecting everyday provincial life. Respectful behaviour toward rangers, wildlife and forest rules aligns visitors with the conservation culture the park has built over five decades.

November to February is the classic season, with cold, clear mornings, dependable trail conditions and the park's famous chilly camping nights. The rainy season greens the forest and suits birdwatching, though trails are wetter and leeches more active.

The high plateau stays cooler than lowland Thailand all year, and cool-season nights are among the coldest recorded in the region, occasionally approaching freezing. March to May is mild, while June to October brings regular rain, mist and lush growth.

The park hosts no festivals, and its appeal is precisely the absence of event crowds. Surrounding towns mark Songkran in April and Loy Krathong in November, and park visitation peaks during Thai school holidays and cool-season weekends.

Arrive by early afternoon, walk a pine-forest trail, and settle into the campground before dusk. Wake before dawn for mist and gibbon calls, hike a longer trail through the morning, then continue along the highway towards Khao Kho or Chum Phae after lunch.

An overnight stay captures the park's best hours at dawn and dusk, while a full day suffices for the main trails and viewpoints. Wildlife watchers and birders often stay two nights to cover more ground at the right times of day.

The park straddles the highway linking Lom Sak in Phetchabun with Chum Phae in Khon Kaen province, and headquarters is signposted off that road. Buses running between Phitsanulok or Lom Sak and Khon Kaen pass the entrance, but a private vehicle is far more practical for exploring.

Park roads connect headquarters, campgrounds and trailheads across considerable distances, so a car or motorbike is needed between zones. Trails themselves are walked, and rangers can advise which routes require a guide or are seasonally closed.

Lom Sak is the nearest sizeable town on the Phetchabun side, with bus connections along the Phitsanulok to Khon Kaen corridor passing the park. The closest airports are at Phitsanulok and Khon Kaen, each a few hours away, after which chartered or rented vehicles complete the journey.

Day visitors are typically admitted from early morning until late afternoon, with registered campers staying overnight. Trailheads may have earlier cut-offs for safety, so confirm times with rangers, especially for longer walks.

Standard national-park entry fees apply, with the usual higher tier for foreign visitors plus small vehicle and camping charges under the Department of National Parks schedule. Fees change periodically, so carry cash and verify at the checkpoint.

A simple canteen and vendors operate near headquarters and the campground in season, serving Thai staples during daytime hours. Options are basic, so campers should carry supplies from Lom Sak or Chum Phae, and hot drinks for cold mornings are worth packing.

Nearby towns serve hearty Isan and central Thai food, from som tam and grilled chicken to noodle soups, with Phetchabun's sweet tamarind sold along the highway in season. Warm jok or a steaming noodle bowl tastes exceptional after a near-freezing park dawn.

Inside the park, campgrounds with tent hire and simple official bungalows serve overnight guests. Outside, Lom Sak and the Khao Kho area offer guesthouses and resorts within reasonable driving distance. Cool-season weekends fill the campground, so book ahead through the park system.

Nam Nao is an economical destination, with modest entry and camping fees and cheap food in nearby towns. Transport is the main cost, and combining the park with Khao Kho or Chaiyaphum attractions makes efficient use of the drive.

Shopping is limited to a small visitor-centre shop and roadside stalls selling fruit, tamarind and snacks along the highway. Stock all camping needs in Lom Sak or Chum Phae beforehand, as the park itself offers only basics.

Wild elephants cross the highway through the park, especially at night, so drive slowly and never approach or feed them. Keep food sealed at campsites, carry warm gear for cold nights, stay on marked trails and inform rangers before longer hikes.

Headquarters, the canteen area and some viewpoints are reachable by vehicle with short, mostly level walks, but trails are natural surfaces and facilities are basic. Wheelchair users will find access limited, though the pine-forest atmosphere near headquarters is partly enjoyable from accessible points.

Rangers and vendors speak Thai with limited English, so a translation app helps with trail information. Sawasdee and khop khun cover courtesies, and the park name is pronounced roughly nahm-now, meaning cold water, a fact locals enjoy explaining.

Book camping ahead for cool-season weekends, arrive with a full tank, and pack far warmer clothing than seems reasonable for Thailand. Drive the highway stretch in daylight for wildlife safety, and ask rangers about recent sightings to choose the best trails.

Bring genuinely warm layers, a good sleeping bag or hired bedding, torch, insect and leech protection in the wet season, cash for fees, and food and water reserves. Binoculars and a telephoto lens greatly enrich wildlife watching.

Observe park rules absolutely: no feeding wildlife, food sealed away from camps, litter carried out and quiet hours respected. Choosing official campgrounds, hiring local guides and reporting wildlife encounters to rangers all support the park's long-running conservation effort.

Khao Kho's attractions and Phu Thap Boek lie west via Lom Sak, while Chaiyaphum's Sai Thong and Tat Ton parks extend the nature circuit east. The Route 12 corridor links Nam Nao with Thung Salaeng Luang National Park for a two-park highland itinerary.

Nam Nao is managed by the Department of National Parks, Wildlife and Plant Conservation, with headquarters and ranger stations along the highway through the park. Contact the park office or check the department's channels for current fees, campsite booking and trail conditions.
