How to travel from St Moritz to Zurich

we were wanting to fly into Zurich from Amsterdam then head straight to Zermatt for 2 nights, go on the glacier express and finish in St Moritz for 1 night and then return to Zurich for a flight to Copenhagen. I can't find out how to get from st Moritz to Zurich, or is there a better way to do it?
