Colline d'Élancourt, Mountain peak in Yvelines, France.
The Colline d'Élancourt is a hill in Yvelines reaching 231 meters high and the highest elevation point in the Île-de-France region. On clear days, visitors can spot the Eiffel Tower, Montparnasse Tower, and the La Défense business district on the horizon.
The site originated from 19th-century sandstone quarrying and later served as a landfill until 1975. During the 1980s, it was redeveloped into a public park that could serve the community.
The hill takes its name from the town of Élancourt and serves as a gathering place for locals and visitors seeking views across the wider landscape. Families and residents use the site for walks and outdoor time together.
The park is accessible via well-maintained paths that lead to the summit without excessive difficulty. It is best visited on clear days when the long-distance views are unobstructed.
During the 2024 Summer Olympics, the hill will host mountain biking competitions, turning it into an international sporting venue. This event has drawn global attention to what was once an overlooked local spot.
