The Parc des Eaux Vives has a surface of 45.000 m2 and is situated at the Quai Gustave-Ador in Geneva, right next at the Parc La Grange. It is a sloping hillside park topped by a historic mansion dating back to the 18th century, that now serves as a hotel and restaurant. The headquarters of the Geneva Sports Association is as well located in this park.
