Cool Underground camp at Helvetia

Started by having an idea about building camp near Helvetia for the Fasnacht event coming tomorrow and I'm usually a underground guy and I had a blast building this with new ideas, especially in a very hidden gem that I've never encountered before but accidentally found it by myself. Sorry for the no music as i'm a deaf person and the fast guide as I just had to do all in 3 minutes. So enjoy the tour !
