Mae Thi Reservoir was constructed under the Royal Initiative of His Majesty King Bhumibol Adulyadej (Rama IX) to address agricultural water shortages in Ban Thi District. Construction began in 1985 (B.E. 2528), and the official opening ceremony was presided over by His Majesty on February 6, 1987 (B.E. 2530), with a total budget of 41,934,360 Baht.

The reservoir has a storage capacity of approximately 5 million cubic meters, supplying irrigation water to over 5,000 rai of farmland, serving as a vital lifeline for the local community.

Unseen Panoramic Scenery in a Mountain Valley

The dam crest is approximately 470 meters wide, with a scenic roadway stretching about 6 kilometers along the reservoir. Surrounded by mountain ranges, especially Doi Wiang rising prominently in the background, the still waters reflect the sky and hills like a natural mirror.

After rainfall, visitors may occasionally witness a light morning mist drifting across the mountain peaks, creating a picturesque and tranquil landscape.

A Favorite Spot for Active Lifestyles

The well-paved road along the dam offers refreshing breezes throughout the day, making it popular among cyclists, city runners, and walking enthusiasts.

Between 4:30 PM – 6:00 PM, golden sunlight glides across the water’s surface, creating breathtaking sunset views that attract photographers and fitness lovers alike.

A Perfect Place for Digital Detox

The area remains largely untouched by commercial development, preserving its peaceful natural setting. In some deeper areas, mobile signals may be weak, making it an excellent destination for a true digital detox.

Visitors can enjoy picnics by the water, listen to birdsong, or even spot water birds and grazing cattle, adding a charming pastoral atmosphere ideal for photography.

Nearby Attractions

Approximately 5 kilometers further in, visitors can explore Huai Hok Waterfall, a scenic natural waterfall suitable for light trekking.

The reservoir is also close to Wat Phra That Doi Wiang, allowing travelers to combine a cultural temple visit with a nature retreat in a single trip.
