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.

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.
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.
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.
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.
The provided information does not explicitly state whether dogs are allowed on the trail or within the gorge. It's best to contact the Bletterbach Geopark Visitor Center directly before your visit to confirm their policy regarding pets.

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 …
