Huai Toei Reservoir

Open Days: Daily

Opening Hours: 06.00 - 18.00

 

Huai Toei Reservoir in Nakhon Ratchasima is a medium-sized irrigation reservoir and a quiet nature attraction in Sa Takhian Subdistrict, Soeng Sang District, Nakhon Ratchasima Province. It is known for its earth-fill dam with a clay core, long dam crest, broad water view, rural surroundings, and a remarkable seasonal landscape called “Mueang Phan Phon” or “Mueang Phan Pluak,” a field of countless earth mounds and termite mounds that becomes visible when the water level drops. The reservoir is suitable for travelers who want a calm local destination, reservoir scenery, photography, a countryside atmosphere, and a deeper understanding of how water resources support farming communities in southern Nakhon Ratchasima.

 

Huai Toei Reservoir is located in Sa Takhian Subdistrict, Soeng Sang District, Nakhon Ratchasima 30330. It is best reached by private car and is suitable for a half-day trip or as part of a wider Soeng Sang nature route. The appeal of the place is its simplicity. It is not a highly commercialized attraction, but a working reservoir surrounded by farmland, open sky, local roads, grassland, and rural communities. Visitors come here to enjoy the view from the dam crest, take photographs, observe the reservoir landscape, and experience a quieter side of Nakhon Ratchasima away from the more crowded routes.

 

Structurally, Huai Toei Reservoir is an earth-fill dam with a clay core. Construction began in 1999. The dam crest is 8 meters wide, 1,935 meters long, and 13 meters high. The reservoir can store 4.1 million cubic meters of water. Its average annual inflow is about 4.07 million cubic meters, while average annual rainfall in the area is about 1,000 millimeters. The irrigation benefit area covers around 4,000 rai, and water is distributed through a 14-kilometer concrete canal system. These figures show that Huai Toei Reservoir is more than a viewpoint. It is an important water management structure that supports local agriculture and community life.

 

The name “Huai Toei” reflects the connection between a local stream and the natural landscape of Sa Takhian. The reservoir was created to store seasonal water and help manage water availability during dry periods. In a rural agricultural area, this role is significant because water security directly affects crops, livestock, and household livelihoods. For travelers, the reservoir provides a visible example of how irrigation infrastructure, natural terrain, and rural communities work together in northeastern Thailand.

 

The main charm of Huai Toei Reservoir lies in its open and unpolished scenery. From the crest of the dam, visitors can see the reservoir stretching across the landscape, with grasslands, trees, fields, and local villages around the edge of the water. The atmosphere is quiet and spacious. It is a place for slow travel rather than fast sightseeing. Visitors can walk along safe viewing areas, sit quietly by the water, photograph the dam and reservoir, and enjoy the rural rhythm of Soeng Sang District.

 

The most distinctive natural feature associated with Huai Toei Reservoir is Mueang Phan Phon, also known locally as Mueang Phan Pluak. This area appears when the water level recedes and reveals hundreds to thousands of earth mounds and termite mounds scattered across a wide section of the reservoir basin. Some mounds are covered with small plants and trees, creating an unusual landscape that looks like a natural miniature city. The formation is a seasonal sight, shaped by the interaction of soil, water, vegetation, and time. It has become one of the most unusual natural scenes in Soeng Sang District.

 

Mueang Phan Phon is most impressive during the low-water season, especially in the late afternoon when warm light falls across the mounds and creates strong shadows. For photographers, the scene offers a rare composition of landforms, reservoir edges, rural sky, and natural textures. When the reservoir is full, parts of the mound landscape are covered by water, giving the area a completely different appearance. This seasonal transformation is one of the reasons Huai Toei Reservoir is worth visiting at different times of the year.

 

Beyond its scenery, Huai Toei Reservoir clearly demonstrates the role of medium-sized reservoirs in Isan’s rural water systems. The reservoir supports around 4,000 rai of agricultural land and distributes water through a 14-kilometer concrete canal. This irrigation system helps farmers access water when rainfall is uneven and strengthens the resilience of surrounding communities. A visit to the reservoir therefore provides more than a scenic stop. It also shows how water infrastructure supports food production and rural livelihoods.

 

The main caretaker of Huai Toei Reservoir is the Lam Plai Mat Operation and Maintenance Project under the Royal Irrigation Department. This agency is responsible for water management, irrigation operation, canal maintenance, and dam-related works in the area. Public procurement information from the Royal Irrigation Department also shows continuing maintenance work at the headworks area of Huai Toei Reservoir in 2026, confirming that the site remains an active irrigation structure under official supervision.

 

The main zones of Huai Toei Reservoir can be understood as the dam crest, the reservoir basin, the irrigation headworks zone, the concrete canal system, the seasonal Mueang Phan Phon area, and the local community zone around Ban Huai Toei Phatthana. Each zone offers a different travel experience. The dam crest is best for wide reservoir views. The reservoir basin is suitable for landscape photography. The seasonal mound area is the most unusual natural feature. The surrounding community zone helps visitors understand how the reservoir is connected with farming, livestock, and local life.

 

For travelers looking for a quiet nature stop, Huai Toei Reservoir is best enjoyed slowly. It is suitable for sitting by the water, taking wide landscape photos, enjoying the breeze, and observing the changing terrain. Visitors should bring drinking water, sun protection, comfortable shoes, and a hat, especially if they plan to walk near the seasonal mound area during low water. Some ground surfaces are uneven and natural, so walking carefully is important.

 

The best time of day to visit is early morning or late afternoon. These periods offer softer light, a cooler temperature, and better conditions for photography. The late rainy season and cool season provide greener surroundings and more pleasant weather. The low-water period is the best time to see the mound landscape of Mueang Phan Phon. Because the view changes with the water level, a visit in one season may look very different from another visit in a different season.

 

Huai Toei Reservoir can be combined with several nearby attractions in Soeng Sang District. Travelers may include Nong Lak Sila Community Forest, Wat Soeng Sang, Hat Chom Tawan, Lam Plai Mat Reservoir, and the Soeng Sang side of Thap Lan National Park in the same route. With half a day, the best focus is Huai Toei Reservoir and Mueang Phan Phon. With a full day, visitors can continue to Hat Chom Tawan or Lam Plai Mat Reservoir for a broader nature itinerary.

 

Getting There is easiest by private car. From Nakhon Ratchasima city, travel toward Soeng Sang District, then continue to Sa Takhian Subdistrict and the Ban Huai Toei Phatthana area. From Soeng Sang town, local roads lead toward the reservoir. The final approach is through rural roads, so drivers should be careful during rain, after dark, or when road surfaces are uneven. Private transport is strongly preferred because it allows visitors to combine the reservoir with restaurants, cafes, nearby viewpoints, and accommodations in Soeng Sang.

 

Visitors using public transport should plan more carefully. They can travel to Soeng Sang town first and then arrange local transport to Sa Takhian Subdistrict. Because the reservoir is located in a rural area, direct public access is limited. A private vehicle gives the most flexibility and makes it easier to continue to nearby attractions, local restaurants, or accommodations after visiting the reservoir.

 

Once at Huai Toei Reservoir, visitors should first observe the dam crest and the overall scale of the reservoir. The long crest gives a clear understanding of the reservoir’s structure and its role in holding water. After that, visitors can choose a viewpoint or, during the low-water season, continue toward the Mueang Phan Phon area. When the water level is high, the best activity is to enjoy the water scenery and the rural surroundings instead of entering low-lying ground.

 

Huai Toei Reservoir is suitable for several types of travelers. Families can stop here for a quiet nature break and photography. Groups of friends can combine it with cafes or restaurants in Soeng Sang town. Nature-focused travelers can use the reservoir as a place to understand local geography and seasonal landforms. Photographers will find distinctive compositions at the dam, the reservoir edge, the mound landscape, and the sunset-lit countryside.

 

Safety and responsible travel are important at Huai Toei Reservoir. Some areas are part of an operating irrigation system. Visitors should avoid restricted operational zones, water control structures, and unstable ground. Swimming in unmarked areas should be avoided. During or after heavy rain, soil surfaces may become slippery or soft. Visitors should also avoid damaging the earth mounds, disturbing vegetation, or leaving waste in the area. Keeping the site clean helps preserve both the reservoir landscape and the local community environment.

 

Food and refreshment options are mainly found in Soeng Sang town rather than directly at the reservoir. Travelers can plan a meal or cafe stop before or after visiting Huai Toei Reservoir. Publicly listed nearby options include WANA KOFF, Bella Barley Berry Ice Cream, Café Addict Sushi & Bar, Ran Derm Soeng Sang, Khrua Sai Fon, and Sukrom Sunthariyasathan. These stops make a trip to the reservoir more convenient, especially for visitors planning a full-day route around the district.

 

For accommodation, visitors can stay in Soeng Sang District or nearby areas. Publicly listed options include Sai Fon Resort, Panisara Resort, Saowanee Resort, Soeng Sang Resort, and Ban Suan Dong Yen Resort. Staying overnight is suitable for travelers who want to visit the reservoir early in the morning or late in the afternoon, continue to Hat Chom Tawan, explore Lam Plai Mat Reservoir, or travel more slowly through the nature and rural landscapes of Soeng Sang.

 

Huai Toei Reservoir is valuable because it is more than a scenic water body. It combines irrigation infrastructure, rural geography, agricultural benefit, a seasonal natural phenomenon, and community life. In one place, visitors can see how a reservoir stores water, how communities depend on that water, and how nature creates unexpected beauty when the water recedes. This combination makes the reservoir especially meaningful for travelers interested in authentic local landscapes rather than highly developed tourist sites.

 

Overall, Huai Toei Reservoir is one of Soeng Sang’s quiet nature destinations that rewards travelers who appreciate simple landscapes, open space, and seasonal change. It offers a different perspective of Nakhon Ratchasima beyond the well-known routes of Khao Yai and Wang Nam Khiao. With its long dam crest, rural reservoir scenery, seasonal Mueang Phan Phon landscape, nearby community forests, local restaurants, and simple accommodations, Huai Toei Reservoir can become a complete slow-travel route in southern Nakhon Ratchasima.
