Great cave at the end of the 1000er Stägli. The route in the cave is well marked with arrows.

Hello my dears :-) First of all, I wish you all a happy new year 2026! 🎉✨ Today I went on a varied and impressive hike. I started in Aarburg at the public parking lot, from where the trail immediately climbs over 1000 steps, though there are actually 1150 steps in total. The ascent becomes significantly steeper, especially from about the last 900 steps: it gets much steeper, and the steps are higher, which takes a considerable amount of effort. But it's worth it, because at the top, a lovely barbecue area awaits, perfect for a well-deserved break. The trail continued past Born up to the Stein (718 m above sea level). From this point on, there are repeatedly impressive views down to the Aare River, and on a clear day, the view of the Alps is simply stunning. A particular highlight was the Heidenhöhle (Heathen Cave). A headlamp is highly recommended for this section, as it's quite dark inside the cave. Afterwards, the trail zigzagged. The Little Matterhorn, which I already knew, once again served as a nice landmark along the route. Sure footing is required for this section; hiking poles may be helpful for some hikers. Finally, the route led me comfortably back to the parking lot, leaving me satisfied and with many wonderful memories. A truly successful hike that perfectly combined nature, exercise, and impressive views. 🥾🌲 Highlights I experienced: - 1000 Steps :-) - Heidenhöhle Cave - Little Matterhorn Lowlight: - None FYI: Here's the video (Part 1): relive.com/de/view/vZqNKKdow3v Here's the video (Part 2): Coming soon Equipment: Standard hiking gear FYI: Easy hike Difficulty: T1 (Hiking) I wish you all the best and happy hiking!

After rock shedding was discovered near the Column Grotto in the fall of 2022, the municipality carried out various investigation and remediation work. During this time, the sandstone cave was closed. The investigation and remediation work has since been completed. Thus, there is essentially no longer any safety risk while in and around the Column Grotto. Every effort has been made to prevent any further rock shedding. However, a residual risk of natural hazards cannot be completely ruled out.

Exciting place, also for children. They shouldn't be too small. You climb a bit and should bring good light.

Heideloch or Heidechuchi is a rock crevice that you can crawl through. Permanently installed iron grips provide the necessary hold. A few meters south of the Heideloch, you will find the Flädermus-Stübli. This cave is about 20 meters long and about 10 meters deep.

Brittnau offers a variety of subterranean experiences, including natural rock crevices, conglomerate rock caves, and historical sandstone mining caves. These provide different exploration opportunities, from crawling through narrow passages to observing formations shaped by human activity.
Yes, the Heideloch Cave, also known as Heidechuchi, is a rock crevice that can be crawled through using fixed iron handholds. It is noted to be suitable for children, provided they are not too young, offering an exciting yet accessible experience. Good lighting is recommended.
The Hügeliloch Cave is a 20-meter deep conglomerate rock cave. At its entrance, visitors can stand comfortably, but further inside, you must proceed on your knees. It is also steeped in local legends, particularly the tale of the 'Hügelimeitli' (noble lady) and a hidden treasure.
The Sandstone caves near the Staffelbach shooting range are a result of historical sandstone mining. It's important to note that access has been restricted due to rockfall danger, and the area is adjacent to a shooting range, meaning the caves are not accessible during shooting operations. Always check local conditions and respect any closures.
Yes, the Sandstone Caves and Fire Pit, Aargau, also known as the Column Grotto, is another site resulting from sandstone mining. While it was previously cordoned off due to rock shedding, remediation work has been completed, and the safety risk has been significantly reduced, though a residual risk of natural hazards cannot be completely ruled out.
The Flädermus-Stübli is a cave located a short distance south of the Heideloch Cave. It extends approximately 20 meters in length and reaches a depth of about 10 meters, offering another interesting subterranean exploration opportunity in the vicinity of Brittnau.
For caves like Heideloch, which involve crawling, bringing good lighting is highly recommended.

Always prioritize safety and local advisories.
The sandstone caves, particularly those near Staffelbach, offer a glimpse into the region's industrial past, as they are a result of historical sandstone mining operations. This provides a unique blend of natural exploration and historical context, showcasing how human activity has shaped the local landscape.
