Lam Nam Nan National Park in Uttaradit Province is a scenic protected area known for mountain ranges, fertile forests, watershed streams, the reservoir above Sirikit Dam, nature trails, waterfalls, and rich wildlife. The park contains several forest types, including mixed deciduous forest, dry dipterocarp forest, dry evergreen forest, and hill evergreen forest. It is also an important watershed area feeding the reservoir above Sirikit Dam. Wildlife found in the park includes barking deer, deer, wild boar, bears, and more than 200 species of birds, making it a valuable destination for nature lovers, birdwatchers, hikers, families, and travelers seeking a quieter side of northern Thailand.

 

Lam Nam Nan National Park was officially declared a national park on September 30, 1998. Its highest point is Phu Phaya Pho Mountain, rising approximately 1,350 metres above sea level and forming part of the boundary between Phrae and Uttaradit provinces. Because of its elevation, forest cover, and mountain landscape, the park has a cool climate throughout much of the year. Rain is common from May to September, while the cool season brings lower temperatures, making it especially suitable for camping, sightseeing, walking trails, and reservoir views.

 

The park is distinctive because it combines mountain forest, freshwater ecosystems, reservoir scenery, wildlife habitats, waterfalls, and educational attractions in one area. Visitors can explore viewpoints, walk nature trails, learn about freshwater fish, visit rock rapids, enjoy the view of the Sirikit Dam reservoir, or stay overnight in the park. This variety makes Lam Nam Nan National Park suitable not only for serious nature travelers but also for families and first-time visitors who want an accessible introduction to the natural landscapes of Uttaradit.

 

The Sirikit Dam reservoir is one of the most important landscape features of the park. Covering approximately 203 square kilometres, the reservoir contains many islands and scenic water views surrounded by mountains. It is suitable for raft trips, sightseeing, photography, and peaceful relaxation. In the morning and late afternoon, the light over the water creates a beautiful atmosphere, especially when the surrounding hills are reflected on the surface of the reservoir.

 

The Freshwater Fish Exhibition Building is a good stop for families and educational travelers. It displays various freshwater fish species such as Indonesian barb, giant snakehead, and other fish connected to the local river and reservoir ecosystem. The building is open from 08.00 to 17.00. This attraction helps visitors understand how forests, streams, reservoirs, and aquatic life are connected, making the park more than just a scenic outdoor destination.

 

The viewpoints along the Pa Daeng, Nam Krai, and Lam Nam Nang Phaya routes are among the most scenic parts of the park. The road follows mountain slopes and passes through dry evergreen and hill evergreen forest, creating a cool and refreshing atmosphere. Along the way, visitors may see wild orchids, Himalayan cherry, ferns, and other forest plants. The route is especially attractive for slow scenic drives, nature photography, and travelers who enjoy quiet mountain roads.

 

Lam Nam Nan National Park has 2 nature study trails, approximately 2.5 kilometres and 4 kilometres long. Both routes include viewpoints and opportunities to see the Sirikit Dam reservoir from natural vantage points. Walking these trails allows visitors to observe different forest structures, seasonal vegetation, and the relationship between mountain forests and watershed systems. Visitors should wear suitable shoes, bring drinking water, and ask park officers about trail conditions before setting out, especially during the rainy season.

 

Nang Phaya Rapids is a natural rock rapid in the middle of Lam Nam Nang Phaya. The area features large and small rocks descending along the stream, with water flowing throughout the year. It is a beautiful place to observe flowing water, forest scenery, and natural rock formations. Visitors should be careful around the stream, especially during or after heavy rain, because water levels and currents can change quickly.

 

The park also contains several waterfalls, including Choeng Thong Waterfall, Huai Mun Waterfall, and Doi Pha Mok Waterfall. These are small waterfalls with water flowing throughout the year because they are located in fertile watershed forest. Choeng Thong Waterfall and nearby waterfall areas are easier to access from the Phrae side. From Phrae city, travelers can drive toward Wat Phra That Cho Hae, then turn left and continue for about 9 kilometres. This route is useful for visitors who want to combine Phrae cultural travel with nature attractions in Lam Nam Nan National Park.

 

Phu Phaya Pho Mountain is the highest point of the park and one of its most important natural features. At about 1,350 metres above sea level, it helps create cooler conditions and supports diverse forest types. The mountain also plays an important role as part of the watershed system. For travelers interested in ecology, the mountain landscape helps explain why the park contains many types of plants, wildlife, streams, and viewpoints within a single protected area.

 

Wildlife is another important value of Lam Nam Nan National Park. The park provides habitat for barking deer, deer, wild boar, bears, and many bird species. More than 200 bird species have been recorded in the area, making the park suitable for birdwatching and nature study. Visitors who want to observe birds should move quietly, use binoculars, and avoid disturbing wildlife. The presence of diverse animals reflects the health of the forest ecosystem.

 

Overnight stays allow travelers to experience the park more deeply. Lam Nam Nan National Park provides accommodation and camping areas. Visitors who plan to stay overnight should contact the park or reserve through the national park reservation system in advance, especially during the cool season and long weekends. Staying overnight allows more time to enjoy the morning atmosphere, reservoir views, nature trails, and quiet forest surroundings.

 

Travelers should prepare properly before visiting the park. Recommended items include comfortable walking shoes, drinking water, a hat, sun protection, rain protection, insect repellent, personal medicine, a flashlight, and a personal rubbish bag. During the rainy season from May to September, trails may become slippery, and some natural areas may require extra caution. Checking weather and trail conditions with park officers before traveling is the safest approach.

 

The best time to visit depends on the activities planned. The rainy season and late rainy season are suitable for lush forest scenery, waterfalls, and streams, while the cool season is ideal for camping, nature walks, and scenic reservoir views. The hot season is still suitable for visiting the reservoir, the fish exhibition building, and shaded forest areas, but morning and late afternoon visits are more comfortable.

 

Getting There from Uttaradit city, take Highway 1045 on the Uttaradit–Sirikit Dam route. The park is about 35 kilometres from the city, around kilometre markers 43–44. The route passes Ruam Chit Junction in Tha Pla District and Huai Charoen Junction. From there, turn left and continue for about 4 kilometres to reach the Lam Nam Nan National Park office. Private car travel is the most convenient option because visitors can also stop at Sirikit Dam, viewpoints, restaurants, and nearby attractions in Tha Pla District.

 

Travelers coming from Phrae Province can access Choeng Thong Waterfall and the Choeng Thong protection unit area by driving from Phrae city toward Wat Phra That Cho Hae. At Wat Phra That Cho Hae, turn left and continue for about 9 kilometres. This route is convenient for visitors who want to combine cultural travel in Phrae with the natural waterfall areas of Lam Nam Nan National Park.

 

Nearby attractions can easily be included in the same trip, especially Sirikit Dam, the reservoir area, raft experiences, viewpoints, and attractions around Tha Pla District. A 1-day trip can focus on the park, the reservoir, and riverside restaurants, while a 2-day 1-night plan allows time for camping, nature trails, viewpoints, the fish exhibition building, and a raft experience on the reservoir.

 

Responsible travel is essential in Lam Nam Nan National Park. Visitors should not leave rubbish, make loud noise, feed wildlife, collect plants or rocks, or walk outside designated trails. The park is both a tourist destination and an important watershed forest. Keeping the area clean and respecting park regulations helps protect the forest, water, wildlife, and reservoir scenery for future visitors.
