Just 15 minutes south of Hua Hin city lies Khao Tao Reservoir, a peaceful spot offering a blend of history, nature and everyday local life.
Known for its scenic views and calming atmosphere, the reservoir has become a popular place to walk, exercise or simply enjoy the sunset — but it also holds significant importance as the first royal-initiated irrigation project in Thailand.
The reservoir was developed in the early 1960s following a visit by His Majesty King Bhumibol Adulyadej the Great. While staying at Klai Kangwon Palace in Hua Hin, the King learned of the struggles faced by residents of Ban Khao Tao, a small fishing village near a turtle-shaped hill. At the time, the community had no access to clean drinking water, and seawater frequently flooded farmland, making it unusable.
A royal project that changed lives
In response, the villagers donated 300 rai of land, and the King personally contributed 60,000 baht to fund the construction of the reservoir. The project began in May 1962 and was officially inaugurated with the King laying the foundation stone on 9 April 1963. The reservoir was designed to store 600,000 cubic metres of water, transforming the area’s prospects for agriculture and daily life.
Over the years, Khao Tao has become known as Thailand’s first “natural classroom.” The King used it as a model for learning about water and soil management, including how to combat salinity and introduce sustainable irrigation methods. The site has since become a symbol of development and self-reliance under royal patronage.
A memorable anecdote from 1953 highlights the King’s connection to the community. While visiting the area by jeep, his vehicle became stuck in the mud. A group of local children helped push it free, unaware at first of the King’s identity. That moment — and the King’s humble interaction with the children — is remembered fondly to this day.
Murals near the reservoir even depict the scene, serving as a reminder of the area’s royal connection.
A place for exercise, reflection and community
Today, Khao Tao Reservoir is more than just a body of water. It’s a recreational and community space, popular with locals and visitors alike. A 2.4-kilometre walking path surrounds the reservoir, equipped with outdoor fitness equipment, offering an ideal place for morning jogs or evening strolls. The area is especially scenic at sunset, attracting photographers and those looking to unwind in a natural setting.
A highlight of the reservoir is its floating pavilion, inspired by the royal pavilion inside Phraya Nakhon Cave. Illuminated at night, it adds a striking focal point to the already photogenic landscape. Nearby attractions include Wat Khao Tao and Wat Tham Khao Tao temples, a scenic viewpoint atop Khao Tao Hill, and the Baan Khao Tao Handicraft Centre, where visitors can buy locally made textiles.
Cafés, small guesthouses, and roadside food stalls now dot the area, making it easy for visitors to spend a few relaxing hours here. For those interested in learning about royal development projects, or simply looking for a quiet spot to enjoy nature, Khao Tao Reservoir offers a meaningful and rewarding visit.
Every November, the reservoir comes alive with the excitement of traditional Thai long boat races — a colourful, fast-paced event that draws large crowds and showcases local sporting spirit. Also in November, the reservoir is one of Hua Hin’s main locations for celebrating the Loy Krathong festival. As night falls, candlelit offerings are floated on the water, creating a magical scene against the reservoir’s calm surface.
