We took an entire day train ride on the Glacier Ezpress from Zermatt in the west of Switzerland all the way to St Moritz in east.  That day on the train seeing the Swiss countryside made the trip worth it right there.   The next day we then took a train from St. Moritz down to the Italian town of Tirano.  We got some great pictures on the way and then on the way back we took a cable car up to the Morteratsch glacier.  You could actually walk onto the glacier which was really cool.   We spent some time in St. Moritz just wandering around and it is pretty nice.   In the winter of course it is a major ski resort for the rich and famous.   When we were there it was for the poor and non famous.
