From Mont Tendre - the highest peak in the Vallée de Joux (1679 metres above sea level) - affords a fantastic view of Lake Geneva and the Savoy Alps all the way to the Bernese Oberland. The whole region with its many beautiful vantage points is a paradise for hikers, horse and mountain bike riders.
The Lac de Joux at an altitude of 1000 metres above sea level is the biggest water surface in the Jura Massif. Famous for its winds, it attracts keen windsurfers and sailors as well as other water sports enthusiasts and bathers. In summer there is a ship service. A railway line runs along the lake and through the pine forest and Jura moorscapes from Le Sentier to Le Brassus which for almost 300 years have been strongholds of the watch-making industry.
The «L'Espace Horloger» museum in Le Sentier provides an insight into the history of chronographs and repeating watches as well as today's production of luxury watches. And the luxury brand Audemars Piguet runs its own museum in Le Brassus. The «Watchmaking Trail» runs from Geneva to Basel, consists of 27 sections and relates the history of watches.
In the "Parc Jurassien Vaudois“ nature preserve hikers find extensive pine forests and the biggest ant colony in Europe which lives spread out over an area of 70 hectares. On the Marchairuz Pass which leads in the direction of Lake Geneva a walk on the Geology Trail and the Jura Flower Trail which is particularly colourful in June and July is particularly recommended. And the Hotel Marchairuz offers refuge if you happen to find yourself in the area on a thundery day.
In winter hundreds of ice-skaters enjoy themselves on frozen Lac de Joux. The cross-country skiing paradise in the area of the Swiss-French border is among the most extensive in Central Europe. The wild countryside also delights winter walkers on foot or snow-shoes.
There are smallish ski areas for skiers and snowboarders: in L'Abbaye there are four ski lifts, in Le Brassus and L'Orient three.
