"Ride up the Polybahn for Stellar Views The terrace at ETH Zurich—where Einstein was an alum—lords high above the city for catch-your-breath views beyond to the lake and the Alps. A number of trams will take you to the terrace, but the most fun way to get there is on the fire-engine red Polybahn, one of only two funiculars left in the city, and the most conveniently located. It runs every 2.5 minutes from the Central stop."
