Great hike! A mixture of paths and rocky terrain. It’s steep at the beginning up to Bernstein castle but then it evens out until the base of Hagastein. We did do the outlet path to Egelstein. The view from the sencond castle is beautiful. You can skip spending time at Ramstein castle...it’s mostly just a ruins and the other two are much better! The view a from the second two castles are beautiful! There is no water or trash along the route. It took us around 5 hours with a quick snack stop.
