The History: A Fortress of Resistance
Beyond the gold, the cave has a grittier, documented history. In the years following World War II, these hidden spots in the Țarcu mountains (see more) and Cerna mountains were used by the Anti-Communist Resistance.
- The Silent Shelters: Fighters used Gaura Haiducului as a temporary base because of its strategic vantage point and the fact that it’s nearly invisible from the air or the valley floor.
- The Secret Code: Locals would leave signs—broken branches or specific stones—to warn the "men in the woods" if soldiers were approaching.

The surrounding forest and ground are covered in a thick layer of pristine white snow, and the trees are frosted, creating a quiet, mystical atmosphere.
For centuries, these mountains served as a refuge for haiducs (outlaws)—local Robin Hoods who defied Ottoman or Imperial rule. Legend has it that one of the most famous leaders hid a massive hoard of gold coins and jewelry inside a narrow, hidden chamber of this cave.
The story goes that the treasure was "tied" with a powerful curse: the gold can only be seen by the light of a candle made of human fat, or discovered on the night of Sfântul Andrei (St. Andrew’s Eve), when the mountains "open up." Many have searched for it, but the cave is said to play tricks on the mind, leading seekers into dead ends or sudden drop-offs.
The Hidden Microbiome of Gaura Haiducului
While the legendary gold of outlaws remains hidden, Gaura Haiducului (the Outlaw's Cave) hides a different kind of treasure: a rich and resilient microbial ecosystem. In the darkness of the Locvei Mountains, life thrives on a microscopic scale, driven by the cave's unique karst hydrology.
- Decomposing Bacteria: These are the "recyclers" of the cave. They feed on the organic matter brought in by the Ogașul Găurii stream and the nutrient-rich guano from the bat colonies near the entrance.
- Calcifying Microbes: Certain bacteria inside the cave play a silent role in the formation of minerals. By altering the local pH, they facilitate the precipitation of calcium carbonate, contributing to the slow growth of the cave's stalactites and flowstones.
- Fungal Communities: In the twilight zone of the entrance, various micro-fungi and molds grow on damp surfaces. They form a vital base for the cave's food chain, providing nutrients for tiny cave-dwelling insects (troglobitic beetles).
- Biofilms: On the wet limestone walls, you can find thin, slippery layers called biofilms. These are complex "cities" of bacteria and microorganisms that work together to survive in a low-nutrient environment, often isolated for thousands of years.
Why It Remains a Secret
Unlike the large, mapped caves of Romania, Gaura Haiducului is a challenge even for experienced hikers:
- The Camouflage: The entrance is often choked with dense vegetation and limestone scree, making it look like a simple shadow on a cliff face.
- The Labyrinth: Inside, the cave doesn't follow a straight path; it’s a series of tight squeezes and vertical chimneys.
- The Guardians: As with all deep mountain crevices in Romania, it is a known sanctuary for wildlife.

Frequently Asked Questions (FAQ) - Gaura Haiducului & Gârnic
1. Where exactly is Gaura Haiducului located? The cave is situated in the Locvei Mountains, near the village of Gârnic (a traditional Czech village) and Padina Matei, in Caraș-Severin County. It’s part of the beautiful Banat region in southwestern Romania.
2. How difficult is the hike to the cave? The trail from Gârnic is of moderate difficulty. It follows scenic karst plateaus and forest paths. While the walk itself is accessible to most hikers, the terrain near the cave entrance can be slippery, especially in winter or after rain.
3. Can I visit the cave during winter? Yes, as you can see in our gallery, the cave looks magical in winter with massive icicles forming at the entrance. However, be extremely careful: the path is icy, and wild animals are unpredictable during this season, often seeking shelter in or near cave mouths.
4. Is there really a treasure hidden inside? According to local legends, the outlaw Adam Duma and his band hid their gold in the cave’s deepest recesses. While many have searched for it over the centuries, no official treasure has been found. The "real" treasure today is the cave's unique biodiversity and its stunning limestone architecture.
5. What should I wear when visiting?
- Boots: Sturdy, waterproof hiking boots with good grip (the limestone is slippery).
- Layers: Even in summer, the temperature near the cave entrance drops significantly.
- Light: If you plan to step beyond the entrance, a powerful headlamp is mandatory.
7. Is it safe to enter deep into the cave? We do not recommend going deep into the galleries without professional speleological equipment and experience. The cave is active, meaning water levels can change, and there are vertical sections that require ropes. Stick to the monumental entrance area for the best (and safest) photos.
