Lake Genval: a dream by the water
The history of Lake Genval begins with a bold transformation. At the end of the 19th century, the pond in the Argentine Valley became the playground of Gustave Smets-Mondez, a businessman who envisioned an 18-hectare artificial lake. Inaugurated in 1904, Genval quickly became a haven forBrussels’ elite, drawn by the fresh air of the Sonian Forest and the elegance of the Belle Époque. Symbolically, the bed of the Argentine River, which feeds the lake, still marks the linguistic border between Walloon and Flemish Brabant today.
Strolling along the shores of Lake Genval, you’ll discover a veritable mix of styles: Norman villas with refined woodwork stand alongside Swiss chalets and even a replica of the Petit Trianon at Versailles. The ultimate symbol of the site, the Château du Lac—now a five-star hotel—majestically overlooks the estate. An enchanting setting, which inspired the master Victor Horta, remains today a precious testament to a timeless art of living.
Between lake and forest: the ideal nature getaway
Nestled just 20 minutes from Brussels, Lake Genval stands out as a premier destination for lovers of the great outdoors. Hiking enthusiasts can set out on a roughly 3-km loop trail, an accessible route that offers views of the surrounding villas. For those looking for a longer hike, an 8-km trail winds through the natural landscapes of Walloon Brabant to the village of Rosières. An idyllic outing that can be combined with a visit to the nearby Château de la Hulpe.
To fully enjoy the lake, the area offers a rangeof water activities: pedal boats, kayaks, and paddleboards. For a more unique experience, “cocobo” barges allow you to organize floating meals for up to 15 people. From friendly brasseries like the Café du Lac to gourmet restaurants like L’Amandier—named the best local restaurant by Gault&Millau in 2019—every culinary stop adds the perfect touch to this timeless moment.
