Watching the surise from the summit of Mt. Rigi was one of the most unique/coolest experiences of my life.
If you can, you need to see the sunrise. Wake up early and go to the very top and just sit back and watch the sun come up. It will be an unforgetable experience.
If you're in good shape take the cable car to the summit and hike your way back down. From what I remember, hiking my way back down only took a few hours and it allowed me to stop and check out things that I wouldn't have been able to do otherwise.
I went to Mt. Rigi back in 2000 when I was a 19 year old kid studying abroad and traveling all over the place. So ya, it's certainly been awhile. I stayed at Massenlager Rigi Kulm, which was right at the summit. I have no idea if it's still there or if it's open. (Thankfully I took a lot of pictures and video and also kept a journal, and teach European Geography, so the memories have stayed fairly fresh.
If anyone knows if Massenlager is still open and if it's on tripadvisor, send me a message and I'll write a review of it.
