After the Gondola you continue up a bit further on a ski chair to the Luge start point. The carts are simple plastic affairs with a handlebar. Fully down it acts as a handbrake. If you lift it up off you go. If you pull it further it acts as a normal brake. You can double up with small kids, but then you have to go on the "scenic" road, not the fast one. We got a quick lesson and down we went.
