Phu Kradueng National Park is in Isaan, the northeastern region of Thailand.
Phu Kradueng National Park in Loei Province is one of the best-known national parks of Thailand. Its high elevation is 1,316 m (4,318 ft) at Khok Moei.
The park is closed to visitors during the rainy season (1 June - 30 September).
Phu Kradueng was proclaimed a national park on 23 November 1962, the second national park of Thailand after Khao Yai National Park.
Phu Kradueng mountain, made up of Jurassic and Cretaceous sandstone formations, takes the form of a mesa towering some 1,000 m above the surrounding valleys. The summit plateau is roughly square-shaped and 60 km<sup>2</sup> (37,500 rai) in size, with an average elevation of about 1,250 m. Sloping slightly to the north, its western, southern, and eastern edges are fairly straight and formed by abrupt sandstone cliffs, while the northern part is deformed in a more irregular shape, containing a number of streams and (seasonal) waterfalls. The summit itself, in the southwestern part of the plateau, is inconspicuous. The park occupies an area of 348 km<sup>2</sup> (217,575 rai).
The mountain's steep sides are home to a succession of tropical forest tiers, namely (in ascending order): deciduous (Dipterocarpaceae|dipterocarp), mixed deciduous, dry evergreen, and hill evergreen forests, interspersed with bamboo. In contrast to that, the plateau at the mountain top consists of a sandy pine savanna landscape. Dominant tree species are Siamese sal (Shorea obtusa), Shorea siamensis, Diospyros spp., Lagerstroemia spp., Podocarpis nerriifolius, maple, Pinus murkusii, and Pinus kesiya. The grass fields support a variety of flowers, such as Hydrocera triflora, Torenia fournieri and marigolds. These flowers bloom at different times of the year. Some grow well in the rocky fields including Dendrobium sp. Close to the ground are ferns, mosses, and Serissa sp. Phu Kradung, with its variety of forest types and vegetation, provides abundant food for wildlife community, including elephants, bears, sambar deer, barking deer, serong, squirrel, fox. Birds include White-rumped Shama, black eagle, silver pheasant, red-wattled lapwing, Chinese francolin, and minivets. There is one rare species of turtle called "Tao Poo Loo" or "Tao Hang" which has a long tail and lives in high elevations along streams in the forests.
Phu Kradung is a cool and comfortable all year round. The average temperature is 15°C. In the cool season, temperatures on the coldest nights reach freezing. In the rainy season, the weather can change quickly. Fog and low clouds tend to hang low over the landscape. Cliffs may collapse under their own weight after the soil which underlies the sandstone cap is eroded by heavy rain. Heavy rains can also cause flash floods in the streams which run down the mountain. Thus, the park is closed during June and September every year for visitor safety and forest rejuvenation.

While you are on the top of the plateau there will be no car for you to travel around the plateau. You need to walk all the way long while you are on Phu kradueng (Total distance around 30 km).
Even though, it is about 30 km to walk, but it is worth walking all the way. There are plenty of beautiful trees and flowers for you to take photos.
You can’t bring you own bicycle up to the plateau but you can hire a mountain bicycle while you are up there. The price is around 360 baht.
This is a very old and historic trail, about 5.5 km in length, climbing the southeastern flank of the mountain. It starts from the main park office at an elevation of about 300 m. There are many places to rest on the way up. These rest plateaus are called Sam. At each there are several vendors selling food and drinks, and some provide toilet facilities and/or medical services as well. There are eight of these on the way up. In order of ascent, they are:
The last 1,300 m from Sam Khrae to the top is the hardest and steepest part of the hike. There are ladders and ramps at parts where it would otherwise be impossible to walk. Once reaching the highest point of the trail (1,288 m elevation) at the edge of the summit plateau, it is still a 3.6 km walk over flat terrain to the Wang Kwang Visitor Center and campsite, where tents and rooms are available.
Many climbers hire porters to carry their belongings to the top of the mountain for them. As a result, the main trail is often crowded with long lines of porters and following climbers.
Travelers can climb the mountain from Amphoe Nam Nao along a trail opened in 2005. There aren't any places to stop and purchase food and drinks on the way up on this trail.
There are many hiking trails to the many cliffs and waterfalls on top of Phu Kradueng. There are two categories of trails on the summit plateau. The first one is the normal trails open to the public, while the second one is the trails in the closed off forest. In the first category, there's a waterfalls trail and a cliffs trail. The closed forest has two areas, named area one and area two.
Starting from the visitor center on the mountain, travelers can explore the cliffs trail.
Phu kradueng is known as the second best of Thai national park. This national park is unique because of beauty of nature like trees, flowers, waterfall, and cliff.
Another unique part of Phu Kradueng is restaurant located at the Visitor center and some spots. There are many restaurants for travelers to choose from such as stir fry Kai Land and crispy pork.
After a long walk, there will be a dessert waiting for you at Pha Yeab mek (around 30 baht).
The park has camping facilities available. The park website has no information on this, but Thai national parks commonly rent tents, sleeping bags, etc., for a nominal fee.
