About 10m off the path, there is a small cave and a small "gorge". At the end of this "gorge", another cave entrance can be seen. I suspect that the whole thing used to be a large cave that collapsed a long time ago.

The view of the gorge is very beautiful but not passable with larger dogs. Unfortunately we had to turn around!

Fabulous hike, well-signed, a few dicey spots here and there but overall a spectacular canyon with an unparalleled opportunity to experience it on wooden bridges and stairs

Unfortunately, the inn is closed on Mondays and Tuesdays (as of April 2024) The hiking trail is very beautiful, sturdy shoes are recommended.

The comment: only for experienced hikers should be taken seriously!! The gorge has not been renovated, there are numerous trees lying across the gorge and the water has often taken its own path and washed over the hiking trail. I would not recommend it, the Nature Friends/Alpine Club have not been to the gorge for years!!

Very difficult for dogs to walk on, as the wooden planks are far apart and the dogs slip through with their paws. Risk of injury!

Very interesting gorge, to explore in about 90 minutes by circular route. There was no water downstairs with us.

The two most prominent and popular gorges in the vicinity of Gratkorn are the Kesselfall Gorge near Semriach and the Rettenbachklamm, uniquely located within the city area of Graz. Both offer impressive natural beauty and well-maintained trails.
Yes, both the Kesselfall Gorge and the Rettenbachklamm are considered family-friendly. The Kesselfallklamm features an adventurous trail with ladders and bridges, while the Rettenbachklamm offers an accessible path through a diverse ecosystem. Sturdy footwear is recommended for both.
You can expect to see numerous waterfalls, rapids, and unique rock formations. The Kesselfall Gorge is known for its cascades and the 'Stone Gate' rock formation. The Rettenbachklamm showcases small waterfalls, moss-covered rocks, and ancient magmatic diabase rocks of volcanic origin, alongside a rich flora and fauna including fire salamanders and rare bird species.
The gorges are particularly pleasant during warmer months as they remain cool and shady. After rainfall, caution is advised due to potential slippery conditions on paths and wooden walkways, especially in the Rettenbachklamm.
The Kesselfall Gorge and Rettenbachklamm trails are generally considered intermediate, requiring sturdy footwear and some sure-footedness. However, there is also a more challenging Gorge trail with waterfall near Graz-Umgebung that is recommended only for experienced hikers due to unrenovated sections and natural obstacles.
Near the Kesselfall Gorge, you can find the traditional Sandwirt inn in Augraben, which offers refreshments, a playground, and a small animal corner. The Rettenbachklamm is easily accessible from Graz, meaning city amenities are close by.
Entry to the Kesselfall Gorge is on a donation basis. These donations are used to maintain the paths and bridges within the gorge. The Rettenbachklamm does not have a formal entrance fee.
While dogs are generally allowed, be aware that the Kesselfall Gorge can be difficult for dogs due to the wooden planks on the ladders and bridges being far apart, posing a risk of injury. The Rettenbachklamm is generally more suitable for dogs, but always keep them on a leash.
Beyond exploring the gorges, the Gratkorn region offers a variety of outdoor activities. You can find numerous mountain hikes, running trails, and general hiking routes. These include paths through wooded hills and along the Mur River, providing diverse options for all activity levels.
The Rettenbachklamm is unique because it's the only gorge located within the city area of Graz, making it an easily accessible natural retreat. Despite its urban proximity, it offers a peaceful experience with no street noise, only the sounds of birds and the murmuring stream. Its special climate supports a diverse ecosystem and showcases ancient volcanic rock formations.
Visitors frequently praise the Kesselfall Gorge for its wild and romantic atmosphere, especially the adventurous trail with over 50 ladders and bridges that allow for an up-close experience of the numerous waterfalls and rapids. It's considered a picturesque and spectacular natural monument, providing a pleasant and cool escape even on hot days.
