Underground cavern from WWII This military installation with two caverns was built at the end of 1940. The larger cavern was to be used as a dormitory for 185 officers and soldiers. All the technical equipment was installed in the smaller cavern. Offices, recreation room and dining rooms were installed in a stationery train in the tunnel. It is not known why, but the installations were never used and still exist, hidden and unused in the Kirchet cliffs. One of the few visitors to the instaliation reported: „The caverns were very luxurious for me: wooden lined walls, heating, running water, flushing toilets, electric lighting ... "

The Rhone Glacier (sometimes also called Rotten Glacier) is a valley glacier in the source area of the Rhone in the extreme northeast of the canton of Valais in the central Alps of Switzerland. It is almost eight kilometers long, has an average width of about two kilometers and covers an area of about 15 km². The glacier was a major tourist attraction, especially in the 19th and early 20th centuries, due to its tongue, which at that time still extended far down into the valley near Gletsch.

Be careful at the entrance where you go from the rubber mat to the ice. I almost fell. I thought the frozen stuffed animals were funny. Nice atmosphere with the blue twilight.

Well, there is not much left of the glacier cave. We visited the cave for the first time in 2017 and are shocked today at what is left of it. The piece of ice in which the cave is located no longer has any contact with the glacier and the second piece covered with fleece also has almost no contact with the Rhone glacier. The glacier cave is the reflection of the Rhone glacier in the future.

A glacier educational trail leads through the picturesque high mountain scenery along the glacier lake to the ice grotto near the glacier tongue. For almost 200 years, this has been carved into the glacier practically every year and inside you can experience a "blue miracle" because the grotto shines in a wonderful blue light. Despite the enormous melting of the glacier, the Rhone Glacier is still almost 9 km long and up to 200 m thick. The glacier movement at the level of the ice grotto in the tongue area is 30 - 40 m annually or up to 10 cm per day; nowhere else in Europe can you get as close to a glacier as in the ice grotto in the Rhone Glacier.

The entrance area with ticket office and souvenir shop is the entrance to the Belvédère ice grotto and the Rhone Glacier. The grotto has been carved into the ice here every year since 1870 - at 2300 m above sea level you can experience the Rhone Glacier up close.

Glacier Grotto, Titlis It feels like you are traveling back in time: in the turquoise-blue twilight of the glacier grotto, where the ice, which is up to 5000 years old, freezes the air we breathe into clouds of mist, the mighty heart of the glacier beats. On the 150-meter-long path 10 meters below the surface, you can feel it under your feet and touch it with your hands. An experience that will touch you in a profound way.

The path in the Aa Gorge leads through a small natural tunnel, nothing spectacular, but very beautiful.

Gadmen is known for unique 'cave-like' experiences rather than traditional limestone cave systems. You can explore deep gorges carved by rivers, natural tunnels, and genuine ice caves within glaciers. These formations showcase the powerful geological forces of the Swiss Alps.
Yes, several options are suitable for families. The Natural Tunnel in the Aas Gorge offers a beautiful hiking experience through a small natural tunnel. The Titlis Glacier Cave is also considered family-friendly, providing an accessible path deep into the glacier.
The Titlis Glacier Cave offers a unique journey 10 meters below the surface of the glacier. You can walk along a 150-meter-long path, experiencing a blue twilight and touching ice that is up to 5000 years old. The temperature inside is a constant -1.5 degrees Celsius, providing a truly cool experience. It's easily accessible from the TITLIS mountain station.
Yes, you can visit the Ice Cave, which has historical significance. This cave was used until the 1980s to store blocks of ice that were then transported to breweries. Additionally, within the Aare Gorge, there's a World War II underground cavern, a military installation built in 1940, though it was never actually used.
The Aare Gorge, located near Meiringen, is an impressive natural monument carved by the Aare River. While not a traditional cave, its 1.4-kilometer length features towering cliffs and sections so narrow they resemble tunnels. Visitors can walk through via secure wooden walkways and carved tunnels, offering a unique 'cave-like' immersive experience within the rock. It's known for its cool temperatures and powerful glacial water.
The Rhone Glacier is a significant valley glacier where visitors can typically explore an ice grotto. However, due to rapid melting and instability, the situation on the glacier tongue can be very dynamic, with risks of collapses. It's crucial to check current conditions and safety warnings before planning a visit to any ice formations there.
The Gadmen region offers a variety of outdoor activities. You can find numerous hiking trails, including routes to the Trift Bridge or around the Stein Glacier. There are also running trails and gravel biking routes that allow you to explore the stunning alpine landscape surrounding these natural wonders.
For ice caves like the Titlis Glacier Cave, dress warmly in layers as temperatures are consistently around -1.5 degrees Celsius. Sturdy, non-slip footwear is also recommended, especially where surfaces might be icy. For gorges like the Aare Gorge, comfortable walking shoes are essential, and a light jacket might be useful due to cooler temperatures inside.
While the main attractions are well-documented, the Aare Gorge itself contains hidden elements, such as the World War II underground cavern. These military installations, though never used, remain hidden within the Kirchet cliffs, offering a glimpse into a lesser-known historical aspect of the region.
The Aare Gorge is generally accessible from spring to autumn and offers a refreshing escape on hot summer days due to its cooler temperatures. Ice caves, like the Trift Glacier Ice Cave, are typically accessible during the summer months when conditions allow for safe passage to the glacier. Always check specific opening times and accessibility for each attraction before your visit, as conditions can vary.
The 'cave-like' formations around Gadmen primarily showcase glacial and fluvial erosion. The Aare Gorge is a prime example of a deep cut carved by a river through limestone, while the ice caves demonstrate the unique formations and blue hues found within ancient glacial ice. These features highlight the powerful and ongoing geological processes shaping the Swiss Alps.
Exploring the Titlis Glacier Cave typically takes about 15-20 minutes for the 150-meter path. A walk through the entire Aare Gorge can take approximately 40-60 minutes, depending on your pace. Allow additional time for travel to and from these locations, especially for the Trift Glacier which involves a cable car ride and a hike.
