Lac du Val-Joly

Lac du Val-Joly is an artificial lake near the Belgian border in northern France, set within a natural park. The water is surrounded by forests and rolling green hills, with walking paths along the shores and spots for observing wildlife.

The lake was built in the 1960s to control the flow of the Helpe Majeure river and supply a power station downstream. This project reshaped the landscape and created a new space that people now use for recreation.

The lake serves as a gathering place for people from the surrounding region who visit for walks and watching water birds. It holds a quiet role in local life as a nature spot where visitors escape daily routines.

A recreation center on the eastern shore provides information about trails and activities around the lake. Bring good walking shoes and be prepared for changing weather if you plan to spend time on the hiking paths.

The water is held in place by a system of dams that also generates electricity for surrounding communities. This hidden role makes the peaceful lakeside an important power source for the wider region.
