One day we bought a one way ticket for the Gornergrat train from Zermatt to Riffelalp. It's located at about 2200m and contains a large resort. The way from the station to the resort is not far, but a nice red trolley does its way back and forth to bring visitors at the utmost comfort. The Riffelalp resort is a nice and colored place. After being there for a while, we took the path that goes down back to Zermatt via Winkelmatten. The way is not difficult, it winds inside a wood with a lot of flora. One or two sections turned out to be more steep but we managed. At mid way we found a tee house which also serves light meals. We had a tee and an Apfelshtrudel - the popular apple cake you find everywhere. The path enables nice views of the snowy mountains, which added interest to the trail. It took us about 3 hours - including the rest in the tee house. very reassuring walk, very much recommended.
