Cable cars themselves- and the stations- feel in need of some modernising. It is also quite expensive (nearly €50 for two adults return trip). However this is definitely worth doing if you are in the area and have a clear, sunny day. The views at the top are beautiful, you can see several of the lakes and across to glaciers in the distance. Some nice signposted walks varying from 1hr-4hr, and places to stop for food & drink. You can easily spend half a day at the top. There are also options to walk the descent. They will close the cable cars if there is bad weather forecast, so best to check this before heading up!
