Yes, you can walk from the First mountain station down to the village of Grindelwald, but you should be prepared for a steep and sustained descent. The hike covers approximately 8 kilometers (5 miles) and involves dropping over 1,000 meters (3,300 feet) in elevation. While the path is well-marked and wide, the constant downhill grade can be very hard on the knees and typically takes between 2.5 and 3.5 hours to complete. Most hikers prefer to take the gondola up to First to enjoy the "Cliff Walk" and the hike to the Bachalpsee lake, and then either walk down or use the "First Flyer" and mountain carts for a more adventurous descent. If you choose to hike up from Grindelwald to First, it is a strenuous 4-hour climb that is best suited for fit individuals. The route offers spectacular, non-stop views of the Eiger North Face and the surrounding glaciers, making it one of the most scenic (albeit physically demanding) walks in the Bernese Oberland.
