Hiking
Embark on the Bletterbach Geological Trail, a moderate hike that leads you directly through a dramatic canyon often likened to the 'Grand Canyon of South Tyrol'. You will traverse the gravel bed of the Bletterbach Gorge, where towering rock faces reveal colorful geological layers from ancient periods. This route spans 3.8 miles (6.1 km) with an elevation gain of 914 feet (279 metres), typically taking about 2 hours and 4 minutes to complete. Along the way, you can admire spectacular waterfalls, such as the Butterloch Waterfall, and catch glimpses of the white Dolomite rock of Corno Bianco/Weisshorn.
Before you head out, remember that helmets are mandatory for entering the gorge; you can rent them for free at the GEOPARC Bletterbach visitor center. It is also essential to wear waterproof shoes, as you will be walking on wet rock and crossing the river multiple times. Always check for potential trail closures due to rain or landslides before your visit to ensure a safe experience.
This trail offers a unique journey through the GEOPARC Bletterbach, where you can witness millions of years of Earth's history etched into the canyon walls. The geological layers from the Permian to the Triassic periods provide a fascinating insight into the region's past. It is a prime example of how natural forces have shaped the landscape, making it a notable destination for those interested in geology and natural wonders.

Frequently Asked Questions
What is the terrain like on the Bletterbach Geological Trail?
The trail offers diverse terrain. You'll start on forest paths leading to the gorge entrance, then walk directly through the gravel bed of the stream within the Bletterbach Gorge. Expect towering rock faces, some up to twenty meters high, revealing colorful geological layers. The path can involve walking on wet rock and crossing the river multiple times, especially near spectacular waterfalls like the Butterloch Waterfall. Waterproof shoes are highly recommended.
Is this trail suitable for beginners or families?
While some shorter loops within the gorge are considered easy and suitable for various fitness levels and families, the full trail is rated as moderate. It requires good fitness and sure-footedness, as sections can be steep and resemble secured mountain paths. Walking through the canyon involves navigating wet rock and river crossings. Helmets are mandatory for entering the gorge and can be rented for free at the Bletterbach Geopark Visitor Center.
What are the main points of interest along the route?
The primary highlight is the Bletterbach Gorge itself, often called the 'Grand Canyon of South Tyrol,' with its visible geological layers and opportunities to spot fossils. You'll experience the Descent into the Bletterbach Gorge, enjoy a View of the Bletterbach Gorge, and encounter waterfalls like the Small waterfall in the Bletterbach Gorge and the impressive Butterloch Waterfall. The Bletterbach Geopark Visitor Center is also a key stop.
What is the best time of year to hike this trail?
The best time to hike is generally from late spring to early autumn when the weather is most stable and the trail conditions are optimal. It's crucial to check for trail closures due to rain or potential landslides, as these can impact accessibility. Winter hiking conditions can be challenging, and parts of the gorge may be inaccessible.

Trail Reviews
We hiked every accessible place in the gorge. Can't believe that this should only be 7km. At the head of the valley to Gorz, back through the gorge, back down over the Jägersteig, to the waterfall to the Butterloch and back up. A wonderfully beautiful piece of earth. The pictures cannot reproduce the incredible beauty. You must have seen that. Approx. 4 hours stay in the gorge.
A gigantic, strenuous tour today, with what felt like twice the altitude difference.... and it went stone on stone without end ☺️ Proud to have made it 👍
The section in the river bed above the waterfall consists only of impassable rubble. No fun. The last stretch below the waterfall was closed. Suggestion: Before you start, ask when you get your helmet to what extent the gorge is accessible.
There are many steps down into the gorge and you have to walk through it over many stones! As is always the case, you then have to climb back up again, 250 steps of varying heights! But it's worth it!!!!
The front part of the gorge was well-visited. After we had to bypass the waterfall, we were the only ones left. After the end of the valley, on the way back, we only encountered a couple. Shortly before the ascent, the Yps prehistoric dinosaur group, which had descended from the Weisshorn, was in the valley.
How Komoot gets the time is a bit of a mystery to me. Plan at least 3.5 hours. We spent a total of 5 hours there.
A journey through millions of years ... At the foot of the Weißhorn, a small stream has dug a deep valley into the mountain over the course of several millennia and created a unique natural monument: the Bletterbach Gorge - the Grand Canyon in the Dolomites! Steep rock faces with fantastic geological formations are millions of years old. Footprints, tracks and tracks from dinosaurs, fossil plant remains and shells give us testimony to the climate eons ago! Rushing waterfalls, an adventurous hike in the middle of the bed of the brook littered with rubble - and again and again this fantastic scenery, there you first become aware of your own time span on our earth ... Finally, a philosophical thought: how does it look here in 50,000 Years ago (a geological blink of an eye) - and which creatures then wander through this gorge….
South Tyrol 3rd Tour Short hike through the Dolomites UNESCO World Heritage Site, the Bletterbach Gorge Geopark. Here, the various rock layers reveal more than 40 million years of geological history. We're now well-informed about quartz porphyry, Bellerophon, and marl. 🤓 Unfortunately, the sun is holding back today, otherwise the colors would have been even brighter and, above all, we would have had the fabulous view of the Weisshorn. But it was still very beautiful. 😊
