Looking for info on Highline 179. How far from the bridge is the parking area? I will have a person in my party that has limited mobility, is it a long walk to Ehrenburg Castle? How big is the hill? Any information you can provide would be greatly appreciated. How much time should I plan on spending there? Is 2-3 hours enough? we will be coming from Neuschwanstein and have a hotel in Ruette.
