Tucked in the Rhone Valley of southwestern Switzerland, Fortress Saint-Maurice and Grotte aux Fées form one of the most fascinating military and natural heritage sites in the country. This unique tour combines a visit to an underground military fortification with a guided walk into a limestone cave system, offering a rare blend of engineering, history, and nature. Fortress Saint-Maurice & Grotte aux Fées Combo Tour.
The Fortress Saint-Maurice was built during World War II as part of a hidden Swiss defense strategy. Embedded into the cliffside, the fort was designed to control access through the valley and protect strategic passes. Today, it stands as a museum of military history, showcasing bunkers, weaponry, war rooms, and communication tunnels.
Directly connected to this military complex is the Grotte aux Fées, or “Fairies’ Grotto”—a 500-meter-long show cave featuring underground passages, rock formations, and a dramatic waterfall at the far end. Legend says fairies once lived here, adding a mythical layer to the already dramatic landscape.
This combo tour is popular with travelers who enjoy military history, geology, hiking, and unique cultural sites—all in one trip.
