Our favorite activity while in Zermatt. We arrived via the loop trail (Blatten via Gorner Gorge)…read morewhich put us entering from the far end. This direction of travel through made our trip all down stairs. If you enter the other way (from the entrance where you pay (5.50 each), you'll be going up a bit of short, steep stairs. Either way you choose to go the gorge is amazing. We started the trail in the morning and never met anyone until we entered the gorge, still only meeting 2 people while down in it. Highly recommend! And if you fancy a bit more of a hike we found that loop trail to be great beginning to end.

Very pretty spot but tiny. Two thumbs up for free parking…read more You get there and you wait until the next tour, no more than 20 min. You get on a boat with a "guide" who gives you a few facts and rows you to the end of the lake and back. It takes about 15-20 min. Kind of crummy that you are asked for tips when you leave the boat. All in all it's a nice place to see once.

Super cool cave with a lake inside of it! It's not anything terribly exciting but it's beautiful…read moreand hearing the history of its formation is worth a visit. It was discovered in 1943 after an earthquake, and there's another set of caves behind it which aren't accessible by the boats that you ride in to look at this one. The tour is pretty short, like 20 minutes, but the guides are fun/silly and you can ask them anything. There's a bar in the waiting area (also a gift shop with lots of doo dads) where you can get a nice beer before your boat trip. It's only 10 CHF so pretty affordable!
