My husband and I came out here early Feb, but it was still beautiful. We parked in the free lots close to the start of the trail - we turned right off the main road right at the Wasserfall train stop. The fall was not frozen, but flowing around still-green moss and plants. As others has said, it's an easy trek up to the top of the falls with good shoes and the view is beautiful. Took us about an hour in and back as we took our time, took pics, and stopped a lot. At the top in the summer there appears to be biergartens and perhaps an event station, many other trail heads as well. Unfortunately the bathrooms were locked at the top, but I can image this would be a beautiful place to see in the spring. There was a surprising amount of people here for a wintery Sunday. The sun came out for a sec, enough time to view the castle ruins on the opposite mountain and the green valleys. After leaving, keep heading south to the town of Bad Urach, there is a museum (open on Sundays) and a very cute town with restaurants open. We will be going back for sure to hike up to the ruins and the other trails, it is very extensive!
