Swap the streets of Zurich for the snowy peaks of Mt. Titlis with this day-long trip out of the city. After starting with a tour of Lucerne and a photo stop at Lake Lucerne or the Lion Monument, you'll continue to Engelberg to travel up the mountain by gondola. Then, at the Trübsee middle station, your time is your own to kick back in the snow. Test your nerves on the snow tubing run, or try skiing; rental of the basic equipment and supervision is included. Later, you'll ride the Rotair revolving cable car to soak up alpine views from the summit.
