Passports are required for travel to Switzerland, though visas are not required for stays under 90 days. Zurich has the closest airport to Grindelwald, and then a train, bus, rental car, taxi, or limousine will get you to the mountain village, unless you're descending Eiger, Monch, or Jungfrau, in which case you'll want lots of rope and crampons. Calculate the cost of transportation from Zurich and Geneva Airport here. Mountain climbing packages can also be obtained through various organizations, who will take care of all such details, from airport to summit and back again.

Many travelers enjoy taking the train to Grindelwald. The scenery is unmatched as you gaze out the large windows, passing alpine meadows and picture-perfect mountain views you may remember from your 1,000-piece puzzle days. If you get off at Jungfraujoch, you will be at the highest train stop in all of Europe after having traveled through a mountain tunnel to get there. You can purchase individual tickets or a pass if you plan to do some moving. There is also a cog-train that runs in the summer months, which for Grindelwald is May through October. 

When leaving Grindelwald, allow plenty of time for backward glances, one last photograph, and regretful sighs.
