It’s just like the advertisements and YouTube clips. Lots of fun and quite safe - well, apart from the Trottibikes (like a scooter) where you really needs to be confident. Some Japanese ladies were having a very hard time of it...
The cable car goes a long way up, giving you excellent views all the way. The glider experience was good. Not that much of a rush but a long glide and felt very safe. The little 3 wheeled carts were my favourite. So much so that I did it twice! (Just be careful here - I pad for three experiences thinking that they would be three different experiences, only to find that its not - its three different times on no matter what you choose. After that its 20 CHF for each new choice.)
Anyway, the karts are great - and fast! You could come off quire easily if you went at it too hard. Thankfully more people don’t.
Overall a great experience and definitely worth doing!
