Saas Fee in Switzerland is a car free resort BUT…
Behind the main parking structure on the way into the resort is a decent sized Aire with views down the valley. There is a barrier on entry and you pay for parking at the machines in the parking structure – just as if you were leaving a car there.
There are facilities for fresh and waste water, a small heated hut with toilets/sinks and a few electrical hook-ups. No charge for any of these over and above the parking charge.
It’s about a 15 minute walk to the main ski lifts.
It was quiet when we were there off-season, but I’ve heard it gets very busy at peak times – you’ll be lucky to get a spot on the edge with the views!
The resort itself is a very pretty traditional Swiss village, at 1800m altitude. It offers 145km of Piste and rises up to 3600m so is very snow-sure (the glacier offers summer-ski opportunities too), here is Muffin at the end of September!:-
Unfortunately the prices are typically Swiss – for both ski passes and food etc. in the resort this is the most expensive place we have visited so far!
