Andermatt is about half-way through the Glacier Express route and it seemed like a good place to spend the night. It's a ski town, but it's September, so it's pretty quiet. We checked into a nice, small hotel and took a half hour to walk around town. It's quaint, and not too touristy. We found a great restaurant run by a Swiss guy who married a South African woman and we were intrigued by the menu that had Swiss and South African dishes.
The train out of Zermatt followed the Matter Vispa river down and back towards Visp and then Brig before heading up to Andermatt. We had good weather and great views on our near empty train compartment, but the best views will be tomorrow.
