Matterhorn
The Matterhorn is an amazingly beautiful mountain any day of the year. The beautiful postcards of the peak set against a clear sky are either altered with a computer to remove clouds or taken on an extremely rare day. Most days, there is a trail of clouds floating off to the left of the mountain, almost as if the mountain itself were smoking. I think the smoke trail makes the mountain all the more mysterious.
If you are a climber, try to negotiate your way past the many Japanese tourists with their humungous cameras and designer climbing outfits, and head towards the summit. (It was absolutely amazing the number of Japanese tourists that were in Zermatt, and they all wanted to climb the mountain!)
For the less adventurous, there is a series of cable cars that will take you up the mountain for a beautiful view of the peak. You won't get all the way up (I don't even think we made it high enough up to hit snow), but it's worth the cost of the ride anyway. At the top of the last cable car you can get out and walk around the mountain and explore the area, or pick up the trail and walk a ways further towards the top.
