[Help Needed] Titlis? Matterhorn? Pilatus?

Hello Samantha! You could manage to make a day trip to any of the famous highlights such as the Gornergrat near Zermatt or Kleine Scheidegg/the Jungfraujoch in the Bernese Oberland. Both trips require 4 to 5 hours of traveling for a single journey though, and that may be too much for one day. You can also consider Rochers de Naye above lake Geneva, which takes about 2 hours from Geneva, combined with a boat trip over the lake if you like. The timetable allows you to plan such trips. I suggest you visit Geneva Tourism for more tips. As for costs: depending on your exact plan, you should either buy regular tickets or use a Swiss Half Fare Card. Here's how to calculate which option is best.
