스트렝겔바흐‬에서 가장 멋진 ‪11‬개의 동굴

Impressive large ruin with many fireplaces. If you are sure-footed and have a head for heights, you can climb the tower, which offers a wonderful view. The ascent is on a steep path in the rock with a wire rope as an aid.

If you don't want to go to the Sälischlössli, you can take a leisurely rest here.

I can only recommend the tour of Aarburg Fortress.

The Wartberg has two castle complexes. The Neu Wartburg, today called Sälischlössli, is located on the northern peak, and the Alt Wartburg on the southern peak. The Alt Wartburg may have had a previous building from the 11th century. In the first half of the 13th century, the lords of Ifenthal built the castle, which is still in ruins today. The multi-storey residential tower of the lord of the castle and his family rose to the north. To the south was a walled courtyard with outbuildings. Access to the castle was via a rock path around the south side of the castle rock. The castle was later rebuilt. A transverse wall was built inside the residential tower and a mezzanine floor was built in the basement. A new filter cistern was built in the yard. Source: information board

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.

Imposing historic walls, definitely worth a visit

Mighty fortress / castle on the Aare in the direction of Olten.

A beautiful ruin that also offers a good view. It's a pity there aren't any more rooms, there's only the floor plan. Nevertheless, the walls are imposing and definitely worth a visit.
