A great starting point for the Aare River Trail. The train station is right next to the castle, and there's also free parking. For example, you can take the red train from here to Solothurn and hike back along the Aare River – a beautiful route!

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.

Nice view of Aarwangen Castle 🏰 on cycle route 5 and 8 Olten -> Solothurn. The castle already existed as a knight's complex at the end of the 12th century 👌🏻.

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.

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

With the descent from Bannwil down, it can be easily integrated into the traffic. No bike path of its own and a lot of traffic. Beware of the bridge, it often jams. After the bridge, however, you can turn right again directly over the railway tracks onto the cycle path.
