From the Lech Valley over the old Gaicht Pass (also: Gacht Pass), the path leads you further to Nesselwängle, to the Haldensee and into the Tannheim Valley.

Worth seeing, reached via a steel staircase, the light is switched on by a presence detector when you enter the tunnel. To the left of it there is a second entrance in the rock face, which can be reached via a path. A beautiful destination for a tour, on a beautiful route.

A medium-sized goblin scrambled out of this tunnel and devoured my friend. Just kidding. It's an interesting little tunnel though, that's for sure.

A real experience, especially in heavy rain. 😉 Don't be afraid, but you become very cautious and start to think about how people used to work there and cross the pass. The numerous wayside crosses and memorial plaques provide clues. I'll repeat it again and can only recommend this section. Impressive, a top highlight!

We always love coming back to the Tannheimer Valley 👍 The hike around the Vilsalpsee, which is nestled in the mountains 😃For me it's always a magical place. Lots of beautiful alpine pastures, and something for every level of difficulty. The Haldensee and the associated campsite are also a fantastically beautiful place. The small Lourdes Chapel in Tannheim, which is located on a small hill above Tannheim, is worth going there. A place of peace, surrounded by forests and lush green meadows, for me a place close to my heart, to unwind and just be happy 🤩🫠

An old iron ore mine was made accessible in 2015 right at the entrance to the old Gaicht Pass. Is accessible at any time.

The best time to visit is generally from spring to autumn (May to October) when the weather is mild and hiking conditions are favorable. Some sites, especially those on trails, might be less accessible or closed during heavy snow in winter.
Comfortable hiking shoes with good grip are recommended, especially for sites like the Old Gaicht Pass which has a steep, gravel track. Dress in layers, as temperatures inside grottoes or tunnels can be cooler than outside, and weather in mountainous regions can change quickly.
The Old Gaicht Pass is noted as a challenging trail, almost entirely over gravel, offering an impressive and demanding experience for those seeking a more strenuous exploration.
While specific rules for each site vary, many outdoor trails and natural grottoes in the region are dog-friendly, provided your dog is on a leash. For historical sites or religious buildings, it's best to check local signage or guidelines. Always ensure your dog is well-behaved and clean up after them.
