The waterfall costs €6, and if you want to go into the cave, it costs €10. The waterfall is stunning and definitely worth the visit. For the truly daring, there's also the option of ziplining over the gorge.

Here lived free from May 12 to August 19, 1944 the maquisards of the secret army of the Megevant group, called "PAN PAN". A little history, even during a mountain bike outing, doesn't hurt!

This bike tunnel is really great. This tunnel used to be a railway tunnel as the cycle path was built on the old railway line. It's also easy to drive through because it's very well lit.

The tunnel is dimly lit, headlights are not a luxury!

Yes, several caves are suitable for families. The Grotte et Cascade de Seythenex is the only developed cave in Haute-Savoie open to the public, offering guided tours and even zip-lines. Other options include the Grotte de la Morette and Pré Rouge, both recommended for family discovery outings, and Les Grottes de Balme, which are accessible year-round.
The Resistance shelter 1944 is a significant historical site where maquisards lived during World War II, offering a unique glimpse into the past within a natural setting. Additionally, the Grotte d'Orjobet in the Salève massif is a historic limestone cavity, accessible via a geological hike.
Absolutely. The Grotte des Sarrasins, located above Lake Annecy, provides magnificent panoramas, especially at sunset. While the cave itself is modest, the hike to it is rewarding for the views. The View from Grotte des Sarrasins is a popular spot for this. Also, Grotte de Sévrier offers stunning views of Lake Annecy and the surrounding towns.
Yes, the Grotte du Grand Perthuis near Talloires-Montmin is uniquely accessible only by water from Lake Annecy. It's an ideal stop during a kayak or paddle outing, offering a refreshing and intimate exploration.
For those seeking a challenge, the Grotte de la Diau in the Bornes massif features an underground river and large natural chambers, suitable for experienced cavers or guided groups. The Grotte de Bange in the Bauges massif reveals a surprising small underground lake after a hike. The Grotte de Barmafi is also considered challenging, requiring some scrambling to reach its impressive limestone formations.
The best time often depends on the specific cave. Developed caves like Grotte et Cascade de Seythenex are typically open from May to September. For caves requiring hikes, such as Grotte des Sarrasins, it's best to avoid wet weather for safety. Generally, late spring to early autumn offers favorable conditions for exploring the region's caves and their surroundings.
For undeveloped caves or those requiring a hike, sturdy shoes are highly recommended. For caves like Grotte d'Orjobet or Grotte de Bange, a headlamp is essential as they are not lit. If you plan water-based exploration, appropriate watercraft and safety gear are necessary.
The region around Annecy offers a variety of outdoor activities. You can find numerous hiking trails, with options ranging from moderate to difficult, such as those detailed in the Hiking around Annecy guide.

Yes, the Our Lady of the Lake Cave offers a different kind of underground experience. It's a well-lit bike tunnel built on an old railway line, providing a pleasant cycle path with views of the lake, rather than a traditional cave exploration.
Visitors appreciate the diversity, from accessible tunnels like Our Lady of the Lake Cave with its lake views, to historical sites like Resistance shelter 1944. The stunning panoramas offered by viewpoints such as the View from Grotte des Sarrasins are also highly valued, combining natural beauty with rewarding hikes.
