It was in the middle of the 19th century that this village in the Jura developed into an alpine spa, being given an additional boost in 1916 with the construction of the railway. The narrow-gauge railway follows a pretty route over 20 km from the shores of Lake Geneva in Nyon, twisting round numerous bends up to Saint-Cergue and then on over the Col de la Givrine as far as the Swiss border at La Cure, the end of the line.
Saint-Cergue is a popular hiking area in the middle of the virtually untouched Vaud Jura Park, a large protected area of national importance, covering 75 km2 between the Col de la Givrine and the Col du Marchairuz. From Saint-Cergue, a popular walk leads through the sunlit Jura woods to the Col du Marchairuz. Between the woods are colourful meadows of wild flowers. The park-like scenery and the splendid views of Lake Geneva and the Savoy Alps are the main attractions of this walk along the Jura Alpine trail. The traditional mountain inn on the Col du Marchairuz offers refuge if you encounter stormy weather – the interesting Park information centre is lower down in St-George.
Another popular hike takes you up to the summit of La Dôle. As well as walking, there are also a number of other less well-known activities available in Saint-Cergue such as grass skiing, grass scootering ("Trottinherbe"), swin golf (a rustic version of golf with a three-sided club and a larger ball) and archery. Last but not least, the area is a paradise for riders and mountain bikers. There is also a via ferrata (fixed-cable climb) for those who like to tackle mountains vertically.
O amplo vale do planalto de Col de la Givrine é uma popular área de esqui nórdico, com 80km de pistas e conexões com a rede francesa de pistas. Alguns teleféricos, principalmente aqueles da pistas a noroeste da La Dôle, levam praticantes de esqui alpino até a elevada área de esqui. Apesar de pequena, com 20km de pistas de nível fácil, é a maior área de esqui noturno da Suíça ocidental. Praticantes de caminhadas de inverno e de raquetes de neve encontrarão trilhas e rotas na neve profunda desta área. Saint-Cergue é um importante centro de treinamento de cães, para serem usados em trenós, e visitantes têm a oportunidade de realizar passeios emocionantes em trenós puxados por cachorros.
