Known as the "top of Europe," the Jungfraujoch is the highest elevation point that can be reached by train on the continent. A trip up will cost you— as will most things you do in Switzerland — but it will also provide you with some of the most breathtaking views you'll see in your life.

Standing 11,300 feet above sea level, you'll be faced with the Aletsch Glacier and the surrounding Alp peaks. Even the train ride offers glimpses into the snowy abyss, as a window in the tunnel leading up to the Jungfraujoch allows riders to look right out onto the glacier. Plus, there's more to do at the top besides explore the Sphinx observation deck: there are shops, an ice palace, and a hike on the glacier for adventurous travelers.
