The ascent to the right via the hiking trail is very steep and fun. Unfortunately, you can't see much of the Schlössli itself and you have no view. One of the fronts is quite nice though. Access to the restaurant in the Schlössli is limited in time. The Schlössli is nice to look at from afar, e.g. from the Alt Wartburg.
