The First Cliff Walk by Tissot in Grindelwald, Switzerland, is widely considered highly worth it, provided you have clear weather. The attraction is a steel walkway that clings to the side of the First mountain, culminating in a 45-meter long "viewing platform" that extends out over the abyss. It is completely free (though you must pay for the gondola ride up from Grindelwald), making it one of the best-value thrills in the Jungfrau region. The views of the Eiger North Face and the surrounding glaciers are breathtaking and offer a perspective you simply cannot get from a hiking trail. For those with a fear of heights, the metal grating allows you to see straight down, which can be dizzying but is perfectly safe. In 2026, it remains a "must-do" because it is accessible to people of all fitness levels—there is no strenuous hiking required to reach it from the cable car station. If it’s cloudy or foggy, however, it’s best to wait, as the experience is almost entirely about the panoramic alpine vistas.
