A Day in Blaubeuren: The Blautopf, an Ice Age Cave & Castle Ruins

I had been looking forward to this day trip for a while. The Blautopf, a glowing turquoise spring at the foot of the Swabian Alb, first drew me in, but the area around Blaubeuren offers much more than just the blue water—medieval streets and a monastery, UNESCO-listed Ice Age caves, and castle ruins overlooking the Blautal valley. Together, they make this small corner of the Swabian Alb an easy place to fill an entire day.

Blaubeuren’s Medieval Center

Blaubeuren’s old town is considered one of the best-preserved medieval centers in southwestern Germany, and it shows as soon as you arrive. Narrow streets, half-timbered houses, and small squares shape the historic center, and remnants of the medieval town wall can still be found around the edges of town.

A gray and white half-timbered house with brick-framed windows sits at the edge of town with trees rising behind it.

One of the most important landmarks is Kloster Blaubeuren, a former Benedictine monastery founded in the 11th century. The complex includes a late Gothic church known for its richly carved choir stalls from the 15th century, as well as a cloister courtyard and herb garden that reflect its monastic past. In the 16th century, during the Reformation—when much of Württemberg broke from the Roman Catholic Church—the monastery was converted into a Protestant seminary.

Just a short walk from the monastery is the Badhaus der Mönche (Monks’ Bathhouse), built around 1510 and believed to be the only surviving monks’ bathhouse in Germany. The ground floor originally housed the bathing rooms for the monastery’s monks, while the upper floor served as lodging for noble guests. Today the building houses the Blaubeuren Local History Museum, and the interior still features beautiful medieval wall paintings in the former ballroom.

The Blautopf: Turquoise Water at the Foot of the Alb

Just steps from the monastery lies the Blautopf, literally “Blue Pot,” one of Germany’s most famous karst springs.

The Blautopf’s bright turquoise water reflects surrounding trees and a half-timbered mill building.

Rainwater falling on the Alb plateau filters through porous limestone before emerging here at the southern foot of the Swabian Alb. On sunny days—especially after a few dry days—the water takes on an almost luminous turquoise-blue. Its color is created by the way light interacts with the fine limestone particles suspended in the crystal-clear spring water.

A stone statue of a woman stands beside the turquoise Blautopf, surrounded by pink flowers and shaded by trees.
The bright blue Blautopf is framed by leafy branches, with a stone structure and plaque visible along the water’s edge.
A closer view of the half-timbered Blautopf mill shows its wooden water wheel turning beside the clear water.

A small yellow house with red shutters stands directly over clear green water beside the Blautopf.
Sunlit green leaves hang over the bright blue surface of the Blautopf, reflecting softly in the water.

Beneath the Blautopf lies the entrance to the Blauhöhle (Blue Cave), an extensive underwater cave system that divers first reached in 1957. Today, more than 11 kilometers (about 6.8 miles) of passages have been explored, and the system is believed to extend even farther.

The spring also inspired poet Eduard Mörike’s tale of the Schöne Lau (Beautiful Lau), a water nymph from the Black Sea who was sent to live in an underwater palace at the bottom of the Blautopf. According to the story, she could only be freed from her sorrow—and finally bear a living child—if she laughed out loud five times. It was the women of Blaubeuren, through their stories and companionship, who slowly brought those laughs from her. Some say that if you stand quietly by the water, you can still hear her laughter rising from below. It’s easy to understand how a place like this inspired such a story.

We had lunch at Blautopfhaus Schönhofer am Blautopf just below the spring basin. In addition to traditional German dishes, the building includes a historic water-powered hammer mill and a small souvenir shop. Sitting by the flowing water made it a pleasant stop before continuing our afternoon explorations.

Kloster Blaubeuren’s church stands beside the Blautopf, with café tables and umbrellas along the water’s edge.

If you have extra time, there’s also a 1.5-kilometer (0.9 mile) historical walking trail with signposts throughout town and the seasonal Blautopfbahnle, a small tourist train that circles the area.

Hiking to Schloss Hohengerhausen (Rusenschloss)

Our next stop took us to Ruine Hohengerhausen, more commonly known as Rusenschloss, which sits above the Blautal valley. The castle was likely built around 1080 by Count Hartmann II of Dillingen. Over the centuries, it changed hands several times before being sold for demolition in 1768. Today, only sections of the walls and archways remain.

A stone archway from the ruins of Schloss Hohengerhausen stands along a narrow forest path surrounded by dense green foliage.
A large stone wall with an arched opening stands on a rocky hillside surrounded by trees under a bright blue sky.
A tall rectangular stone tower remnant stands above a curved defensive wall, overlooking a green valley under a blue sky with scattered clouds.
A turquoise river curves through a green valley below rocky cliffs, with houses and buildings visible in the distance.
A thick stone wall with several small arched openings stands against a bright blue sky, surrounded by green shrubs.

The hike passes rocky outcrops and a small cave known as the “Kleine Grotte,” which we stopped to explore. In warmer months, be prepared for mosquitoes—they were definitely present during our visit.

An arched rock opening frames bright green trees and forest outside, with uneven stone ground and rocky walls inside the cave.
Rough stone steps carved into natural rock lead upward inside a small cave opening with daylight visible through a round hole in the rock.
A narrow rock passage opens to a steep drop with green trees and valley views visible through a tall vertical gap in the limestone.

The ruins sit within a protected landscape area, home to sensitive plant and bird species. From the remaining walls you get wide views over the Blautal valley, with fields, forests, and the Blau River winding below.

Hohle Fels Cave: A Glimpse 40,000 Years into the Past

A short drive from Blaubeuren, in the Ach valley near Schelklingen, is Hohle Fels Cave.

The gated entrance to Hohle Fels Cave is set into a large limestone rock face, with sunlight filtering through trees above.
Two tall limestone rock towers with a circular opening in the cliff face rise above a grassy area with picnic tables below.

A narrow, clear stream reflects bright white clouds and blue sky as it winds through green fields and shrubs.

The cave is one of the largest accessible caverns in the Swabian Jura and part of the UNESCO World Heritage Site “Caves and Ice Age Art in the Swabian Jura,” designated in 2017. This listing includes six caves in the Ach and Lone valleys where some of the oldest known figurative art and musical instruments have been discovered.

Hohle Fels remains an active archaeological site. Excavations here uncovered the Venus of Hohle Fels, a small figurine carved from mammoth ivory around 40,000 years ago, as well as a flute made from the bone of a griffon vulture—among the earliest known musical instruments.

Both Neanderthals and early modern humans occupied caves in this region, including nearby Sirgenstein Cave in the Ach valley. Together, these sites provide rare insight into early human creativity, symbolism, and daily life.

Inside Hohle Fels, the scale of the cavern is immediately striking. The ceiling rises high above, and a cool mist hangs in the air. Standing there, it’s hard to fully grasp that people were carving ivory figurines and making music in this very valley some 40,000 years ago.
