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!

NB! You walk a lot in open areas, without shelter. Better not when it's very hot! Other than that, a nice walk!

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 👌🏻.

It's not far from Oensingen. The more scenic part begins here with the ascent to the rye

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.
