The Fort l’Ecluse : place to discover this summer!

The Fort l’Écluse was erected in the 13th century to face the most tenacious invaders. Being a strategic passage between the Kingdom of France and Savoy, this passage on the Rhône has been the focus of many conflicts over the centuries. Watchtowers, casemates, ammunition chambers… The site is a genuine labyrinth in a protected area of over 1800 hectares.

The Fort l’Écluse is built into a mountainside at the foot of the Grand Crêt d’Eau (1621m), one of the highest peaks in the Jura Mountains!

Facts: This site has a lower and an upper fort, and 1165 steps cut into the rock to form an underground staircase linking the two forts. Up there, visitors can admire the Rhône, the Mont Blanc and Geneva. Keen climbers can even earn a diploma after the 830 steps climb.

Guided tours, temporary exhibitions, bat observation site, Via Ferrata, adventure park, concerts, sound and light show…
