As we continued our exploration, I couldn't help but feel a sense of awe at the sheer power and majesty of nature. These caves were a testament to the Earth's enduring beauty and the wonders that lie hidden beneath our feet.

Exploring the Fascinating History of the Caves

The Traun Grottenbahn caves are not only a natural wonder but also a treasure trove of historical and archaeological significance. Over millions of years, the caves have been shaped by the relentless forces of water and time, resulting in the formation of intricate chambers, tunnels, and awe-inspiring stalactites and stalagmites.

Geological Formations and Unique Features

The caves are composed of limestone, a sedimentary rock formed from the accumulation of calcium carbonate over millions of years. The water that has seeped through the limestone has dissolved the rock, creating the vast network of chambers and tunnels that we see today. The caves are home to a variety of unique geological formations, including stalactites, stalagmites, flowstones, and helictites. Stalactites are formed by water dripping from the ceiling of the caves, while stalagmites are formed by water dripping from the floor. Flowstones are formed by water flowing over the cave walls, and helictites are formed by water dripping from the ceiling at an angle.

Archaeological Discoveries and Evidence of Human Habitation

The caves have also been inhabited by humans for thousands of years. Archaeological excavations have uncovered evidence of prehistoric settlements, including tools, pottery, and animal bones. These discoveries suggest that the caves were used by early humans for shelter, hunting, and gathering. In addition, the caves contain a number of rock carvings and paintings, which provide a glimpse into the lives of the people who lived here centuries ago.

Legends and Myths Associated with the Caves and Their Surroundings

The Traun Grottenbahn caves are steeped in legends and myths. One of the most popular legends tells the story of a dragon that lived in the caves. According to the legend, the dragon was defeated by a brave knight who was able to slay the beast with his magic sword. Another legend tells the story of a beautiful princess who was kidnapped by a wicked sorcerer and taken to the caves. The princess was eventually rescued by a handsome prince who battled the sorcerer and defeated him.

Immerse Yourself in the Beauty of the Unterwelt


The Traun Grottenbahn offers visitors a breathtaking journey through a subterranean wonderland, adorned with stunning stalactites, stalagmites, and otherworldly rock formations. These natural sculptures, formed over millions of years by the relentless dripping of water, create an ethereal atmosphere that is both awe-inspiring and humbling.

As you venture deeper into the cave, the formations become increasingly intricate and diverse, showcasing a vast array of colors and textures. Delicate, translucent stalactites hang like chandeliers from the ceiling, while stalagmites rise majestically from the ground, resembling ancient pillars supporting the weight of the underworld.

One particularly striking formation is the "Drachenmaul" (Dragon's Mouth), a massive stalagmite that resembles the gaping maw of a mythical beast. Its jagged edges and imposing presence evoke a sense of awe and wonder, leaving visitors with an unforgettable memory.

To fully appreciate the beauty of the cave's formations, it is essential to capture their essence through photography. However, cave photography presents unique challenges due to the limited lighting and the reflective nature of the rock surfaces. Experimenting with different shutter speeds, apertures, and ISO settings can help you achieve stunning shots that convey the magic and majesty of the Unterwelt.

Whether you are an experienced photographer or a novice enthusiast, the Traun Grottenbahn offers ample opportunities to capture breathtaking images that will serve as lasting mementos of your subterranean adventure.

The Tropfsteinkammer is another highlight of the tour, with its stunning display of stalactites and stalagmites. These intricate formations, created by the slow dripping of water over thousands of years, are a testament to the enduring power of nature.

Discover the Secrets of the Caves' Inhabitants

The Traun Grottenbahn caves are home to a diverse array of wildlife that has adapted to thrive in the unique underground environment. These creatures include various species of bats, spiders, insects, and even blind cave beetles that have evolved to survive in complete darkness.

Bats: The caves provide an ideal habitat for bats, with their dark, humid conditions and abundance of insects. Several species of bats, including the greater horseshoe bat and the lesser horseshoe bat, can be found in the caves. These bats play a vital role in the ecosystem by controlling insect populations and dispersing seeds.

Spiders: The caves are also home to a variety of spiders, including the long-legged cave spider and the giant house spider. These spiders have adapted to the cave environment by developing long, sensitive legs that allow them to navigate the dark tunnels and capture prey.

Insects: The caves are teeming with a diverse array of insects, including beetles, flies, and springtails. These insects are an essential part of the cave ecosystem, as they provide food for bats and other animals and help to decompose organic matter.

Blind Cave Beetles: One of the most fascinating creatures found in the caves is the blind cave beetle. These beetles have evolved to live in complete darkness and have lost their eyesight over time. They rely on their long antennae and sensitive hairs to navigate the caves and find food.

Observing the Wildlife: To observe the wildlife in the caves, it is important to be respectful and avoid disturbing their natural habitat. Visitors should remain quiet and move slowly, and avoid shining bright lights directly at the animals. With a little patience and observation, visitors can catch a glimpse of these amazing creatures and learn about their unique adaptations to the underground world.

Unraveling the Mysteries of the Caves' Past

Over the years, the caves have been extensively studied by archaeologists, who have uncovered a wealth of artifacts that shed light on the lives of past inhabitants. These discoveries include stone tools, pottery shards, and even human remains, all of which provide clues about the people who lived in the caves thousands of years ago.

One of the most exciting archaeological finds was the discovery of a series of prehistoric rock paintings depicting hunting scenes and other aspects of daily life. These paintings, which are believed to be over 10,000 years old, offer a rare glimpse into the minds and culture of our ancient ancestors.

Another significant discovery was the remains of a Roman settlement that existed in the caves during the 1st century AD. The Romans used the caves as a refuge during times of war and also as a place to store food and other supplies. The remains of the Roman settlement include several buildings, a water cistern, and a number of artifacts, including coins, pottery, and jewelry.

The archaeological excavations at the Traun Grottenbahn have provided valuable insights into the history of the caves and the people who have lived in them. These discoveries have helped us to piece together the story of human habitation in the region and have shed light on the lives of our ancestors who called these caves home.

Capture the Essence of Your Cave Experience: Photography Tips

The Traun Grottenbahn offers a unique opportunity for photography enthusiasts to capture the stunning beauty of the underground world.

To ensure successful cave shots, it's essential to have the right equipment and technical skills.

A sturdy tripod is crucial for keeping your camera steady and avoiding blurry images. A wide-angle lens is also recommended to capture the vastness of the cave chambers. In terms of camera settings, a low ISO and a slow shutter speed are generally preferred to reduce noise and capture the ambient light.

Experimenting with different shutter speeds can create interesting effects, such as capturing the movement of water droplets or the ghostly trails of moving figures. It's also worth playing around with different angles and perspectives to create dynamic and visually appealing compositions.

For beginners, it's a good idea to start with the automatic settings of your camera and gradually adjust them as you become more comfortable with the conditions. It's also helpful to take test shots and review them on the camera's display to make any necessary adjustments.
