During my daily commute from Zurich to Bern, I often noticed a big castle positioned on the Aare River. Finally, after 9 years of commuting I finally visited with a friend. This hike from Outdoor Active is a easy stroll from Olten to Aarburg, followed by a 7 kilometer hike including a 250 meter ascent to the Sälischlössli and a pass by an animal park on the way back to Olten. We included a visit inside the Festung Aarburg, an old castle which is now in use as a Jugendheim (Juvenile Detention Center) for boys aged 16-20. For this reason, visiting the castle is limited and currently, there is only one 1.5 hour tour per week on Saturdays at 14:00 (in Swiss German). It was well worth the visit.
The walk to Aarburg is along the Aare by meadows, train tracks and farms.
At 14:00 on Saturdays, the Festung Aarburg is open for a guided tour in Swiss German (cost 10 CHF). The guide explains the castle’s construction history, life in the castle, how the rooms were used and a bit of how it is used today as a juvenile detention center for boys aged 16-20. The fortress, strategically located at a narrow point of the Aare River, is built into a massive spur of rock with steep walls on the outside.
After the castle visit, we continued to the Sälischlössli, a small castle with a restaurant built in 1870/71 as an expansion of a castle ruin. After the walk up, the Restaurant Sälischlössli is a relaxing place to have an ice cream (or french fries) and a great view.
The way home passes by an animal park. Unfortunately, the raccoons were not out but we did find some handsome deer.
