The sandstone formation Altschlossfelsen, which is designated as a natural and cultural monument and is also the largest rock reef in the Palatinate, is really fantastic. The name comes from a castle built on the rock towers many hundred years ago was built, but has long since fallen into ruin. Beautiful rocks run through the forest for more than a kilometer. Unfortunately often overcrowded on Sundays and public holidays...

It is a scenic highlight. The rocks are worth seeing in terms of size, variety of shapes and color effect. A number of paths can be strolled between the rocks, around the rocks and through crevices in these rocks, and you always discover new places. On the southern ridge there is another viewpoint with a view far into the Northern Vosges.

It is smaller than the upper bear cave. But the shower is an absolute eye-catcher.

These massive rocks never fail to impress me. And what wind, water and sun shapes and leaves behind. Sometimes you can see faces or animals in the rocks. What do you see?

The region around Kröppen is home to several remarkable natural monuments. Among the most prominent are the Altschloss Rocks, known for their massive sandstone formations stretching over 1.5 kilometers. Another must-see is the Upper Bear Cave, the largest natural cave in the Palatinate, featuring an impressive entrance and a spring. Additionally, the Witches' Gorge offers a scenic experience with multiple waterfalls and narrow paths.
The Altschloss Rocks are characterized by extensive sandstone towers and walls, sculpted by centuries of wind and weather. You'll find bizarre and intricate patterns, column galleries, and natural towers, with some fissures wide enough to walk through. A special phenomenon called "Felsenglühen" (rock glow) occurs when the sun illuminates the rocks, creating an intense play of colors, particularly in early April around 7:00 PM or 8:45 AM.
The Obere Bärenhöhle (Upper Bear Cave) is recognized as the largest natural cave in the Palatinate. It boasts an impressive entrance 27 meters wide and 9 meters high, extending approximately 37 meters deep. Above the cave, the Bärenfelsquelle (Bear Rock Spring) emerges, with its water cascading almost 20 meters into a basin, creating a fascinating two-story rock formation.
