The lake was excavated to provide gravel for local construction projects and subsequently converted into a leisure site.
The water quality is monitored regularly throughout the summer season to meet public health bathing standards.
The park serves as a hub for the 'Giffre Pass,' which links various outdoor leisure activities across multiple municipalities in the valley.
Its altitude at approximately 700 meters provides a cooler microclimate compared to the valley floor in mid-summer.
Base de loisirs du Lac Bleu is a 15-hectare recreational area situated in the Giffre Valley at the foot of the Grand Massif mountain range. The centerpiece is a 3-hectare artificial lake created during the construction of the local hydroelectric dam. It features a supervised swimming beach with lifeguard patrols during the peak summer months. Surrounding the water are designated zones for angling, including trout fishing permits. The site offers a range of sporting infrastructure, including tennis courts, a mini-golf course, and a volleyball area. A dedicated trail network connects the lake perimeter to the wider valley walking and cycling paths. The park remains open year-round, though water-based activities are restricted to the warmer months. Picnic tables and grass seating areas are dispersed throughout the wooded sections of the park.

Bring non-slip water shoes, as the lake bed can be pebbly.
Pack a portable shade cover if you plan to stay long, as lakeside trees fill up early.
Carry a light jacket even in summer, as temperatures drop quickly when the sun sets behind the mountains.
Do not attempt to swim in the Giffre river itself, as currents are unpredictable; stick to the managed lake.
Lifeguard supervision and swimming activities are available only during the summer season; park grounds are accessible year-round.
Dogs must be kept on a leash; swimming is strictly prohibited outside of designated, supervised zones.
