Jungfraujoch, one of my favourite places in Switzerland was exhilarating to say the least. While there I visited the Ice Palace, which was super cool…literally too!
The Eispalast or Ice Palace is a terrific experience. After you enter in, the smile on your face gets frozen in time & while you try to oooh & aaah at the novelty of the experience & ice sculptures around you…be careful. You really have to watch your step else you may just slip, fall & find yourself ski-dding all the way down the icy corridors…nothing like a free ski sans the skis 🙂 Don’t go soooo fast that you frip on srippery glound.
Unsolicited advice – make sure your shoes are able to walk you across ice without slipping. For the extra care needed to walk on this surface, I wouldn’t encourage elderly folks to try it.
