The Akechidaira Ropeway, located just off the famous Irohazaka Winding Road in Nikkō, offers unsurpassable views over Lake Chūzenji and Kegon Falls from the top of a nearby mountain. The ride itself is short and not very exciting, but the views are of a kind you won't get anywhere else.
Only here can you truly appreciate the amazing geology of this area, part of Nikkō National Park. The lake is surrounded by mountains on all sides but one, where its waters fall down in a straight line as if trying to escape the confines of its stone basin. Mount Nantai towers to the right, and from late October through November the mountain slopes are ablaze with colors. Winter will present you with the unforgettable sight of Kegon Falls turned into one giant icicle.
Of course, to be able to see all this you need to visit on a clear day. It may get quite chilly at the observation point at any time of year, so bring an extra layer. Also, be prepared to wait in line—Akechidaira is a popular tourist spot and gets crowded on weekends, especially during the fall season.
