The Tivoli Cave in the city of St. Gallen is a small cave in the middle of a beautiful forest. The best way to get there is to take the bus to the "Hagenbuch" stop. Or take the wonderful panoramic path and then descend the Tivoli stairs. Please respect the privacy of the private property there! Continue directly to the right along the small path and DO NOT go left/straight across the small bridge. If you go all the way in (bring a headlamp), you won't get very far. It's almost a bit spooky there. If you look up, you'll see a shaft about 13 meters long that leads straight to the very top. This is where buckets used to be lowered to fetch water. The hole at the top was eventually sealed and covered with earth and no longer exists. Therefore, there was no escape route for the nuns. There used to be a rickety and very rotten wooden ladder here. This has since been removed for safety reasons. It is a man-made cave; clear marks made by tools have been discovered in the rock. The cave is about 17 meters long and between 6 and 7 meters wide. Source: thisismysaintgallen.com/tivolihoehle/

The Felsenkeller is located near the Hoch-Altstätten Castle, a cave with a spherical diameter of about 3 m that was created by human hands and was probably used for storage, unfortunately there are no more doors. "Easy to reach on paths and supply roads from Altstätten, Marbach, Ober Lüchingen or St. Anton ..." also a fantastic mountain bike tour!

A small cave in the rock, possibly an earlier cellar. Protected by a double gate, one side of which, however, was torn off its hinges. Inside a curve with a diameter of about 3m, as well as in height.

The cave is a little hidden, but with the GPS you have to look for a hole in the floor, not a wall entrance. A rope was attached to the entrance through which you can slide down a good 20m. However, due to the difficult underground, I didn't dare to go any further, but it seems to go further. The cave is extremely slippery, even in hot weather, and good shoes, sturdy pants and good gloves are required to go just a few meters into it! CAUTION AND SECURITY ARE REQUIRED! Don't go in alone!

A wall in the rock is bricked up with an old door, the door is open, behind it a small unused rock cellar. Not very exciting.
