Do not think for a minute that this is a tourist trap. It may be one of the greatest days I have…read moreever spent with my family. We took the train to the top of the Gornergrat and were dressed for the cold but layered as we knew we were going to hike back down to Zermatt (estimated to be 4 hours.) At the top it's chilly and I think more often than not the elusive Matterhorn sits teasing its fans with a cloud coverage that just seems to sit in front of the peak. We started the trek down and enjoyed the postcard views. You truly feel like you have been transposed onto a movie set. The scenery is beyond words. The hiking trails are very well marked for the boundless tourists--so you don't feel like you can get lost, but you don't feel too isolated either. Everyone sort of goes their own way and at their own pace so you are on your own.
About a quarter of the way down, the fog burned off and for the rest of our time on the Gornergrat, we had a bucket list view!! Invest in a good camera if you don't already have one.
Of course, you can spend more time than we had in Zermatt and take the train partially up and just hike around the mountain, but if you only have a day, I highly recommend this gorgeous hike. And don't think it's not exercise because it's downhill, our legs were burning and were very sore for 2 days afterwards.
