This is a climbing wall near the town of Schwyz, it's only 15 minutes from the train station. It offers 80+ single pitch routes from 3 to 8c+ up to 25m height. Most routes offer bolts every 2 meters.
It is family and kids friendly. Drawbacks are the railway line which cuts right through the site and the exposition, in the summer shadow comes in the afternoon, which is the preferred time for locals to climb here.
If you are exhausted by the climbing and the heat, you can have a jump into the public swimming site of Lauerzersee (you will see the signs on your way to the wall).
Conclusion: If you want to spend a day climbing, go for a multi pitch route in any of the nearby climbing sides in Switzerland. But if you have kids with you or beginners, or if you just want to spend half a day climbing, the limestone wall of Chaemiloch is a good choice. If you lack any equipment, the next store is just 500m away.
