As a natural monument was previously registered only a subpart, the so-called "cave stone" (450 m above sea level) - a grotto-like undermined rock bank of the Middle Stubensandstein. However, the amphitheater-like final cliffs of the Tobel Canyon are no less worthy of protection.

The natural monument "Hohler Stein" (450 m above sea level) is a large, impressive niche of 30 m diameter at the upper end of the valley of a small brook blade in Stubensandstein. A small waterfall falls 5 meters deep into a wide basin in the rock.
The Stubensandsteinformation consists of a layer package, which contains not only harder sandstone layers but also those with larger, easily flushable claystone lenses. Clay-bound, thus softer sandstones and sandstone slates facilitate such niche or cave formations, as they are typical of many blades of this landscape. The ND "Hohler Stein" is particularly impressive in winter when it is adorned by meter-long icicles and the stream becomes a bizarre ice structure. From here, a footpath continues up stairs and footbridges, where again cave-like formations form a cauldron in the high forest.

Impressive natural monument. Well signposted. It is pleasantly cool here on hot summer days. Not an insider tip, the great, varied gorge to hike through. The Tobel Gorge is a pleasantly cool recommendation, especially on hot summer days. There is a lot going on here on weekends.
