The Jungfraujoch, also known as the "Top of Europe," is a high-altitude saddle nestled between the Jungfrau and Mönch peaks in the Swiss Alps. At 11,362 feet above sea level, it offers breathtaking views and is accessible by the Jungfrau Railway, which boasts the highest railway station in Europe. Visitors can explore the glacier landscape, visit the Sphinx Observatory, and enjoy panoramic restaurants and shops at this iconic alpine destination.
