Nature & Hydrology
Coiba Mare is a complex active cave system, meaning it was carved and is still influenced by the force of water.
- The Underground River: The cave is part of a massive underground hydrological system. The water that enters here travels through the mountain and resurfaces at the famous Izbucul Tăuz, the deepest underwater spring in Romania.
- The "Giant's Mouth": Standing at the entrance, humans look like tiny ants against the sheer limestone walls. It’s a favorite spot for photographers looking to capture the raw scale of the Carpathians.
The locals of the Apuseni (the Moți people) have always treated these caves with respect and a touch of fear.
- The Mountain's Breath: It is said that the cave "breathes." During cold winters, a thick mist often rises from the portal, leading to old folk stories about a dragon or a giant sleeping deep within the mountain.
- Hidden Shelters: During times of war or unrest, these deep karst systems served as natural fortresses for the local communities, hiding their most precious belongings from invaders.

- Seasonal Changes: In the spring, when the snow melts, the cave entrance can turn into a dramatic waterfall or a swirling lake, making it inaccessible but incredibly beautiful to watch from a distance.
- The "Coiba Mică" Neighbor: Just a few hundred meters away lies its "sister," Coiba Mică, which is also spectacular but much tighter and more technical for cavers.
- Entrance Size: 74m wide x 47m high (The largest in Romania).
- Total Length: Over 4,000 meters.
- Difficulty: The entrance area is accessible to anyone, but exploring the deep galleries requires professional caving equipment and high-level expertise due to underground lakes and siphons.
FAQ: Coiba Mare Cave (Peștera Coiba Mare)
1. Is Coiba Mare the largest cave in Romania?
In terms of its entrance, yes. It has the largest cave portal in Romania (74m wide by 47m high). However, in terms of total length, the Vântului Cave (Peștera Vântului) remains the longest in the country.
2. Can I visit the cave without professional equipment?
You can easily visit the massive entrance (the portal) and the first large gallery without any special gear. However, the inner parts of the cave are extremely technical, featuring underground rivers and siphons, and should only be explored by professional cavers.
3. How do I get to the cave?
The cave is located in the village of Casa de Piatră, Gârda de Sus commune, Alba County. From Gârda de Sus, follow the paved and then gravel road for about 12 km. While accessible by most cars, a high-clearance vehicle is recommended in bad weather.
4. Is there an entrance fee?
As of now, there is no official entrance fee to visit the portal of Coiba Mare. It is a wild cave located within the Apuseni Mountains (see more), so we ask all visitors to respect the environment and "leave no trace."
5. When is the best time to visit?
Summer and early autumn are best for easy access. In the spring, during the snowmelt, the cave can become a "sinkhole" for massive amounts of water, making it dangerous to go inside. In winter, the area is spectacular but often covered in heavy snow.
6. Do I need a flashlight?
Even if you only visit the entrance, a strong flashlight or headlamp is highly recommended to see the impressive details of the limestone walls as you step further away from the natural light.
7. Are there other attractions nearby?
Yes! You are in one of the richest karst areas in Europe. You can also visit Coiba Mică, Ghețarul de la Vârtop (The Vârtop Ice Cave) (see more), and the famous Izbucul Tăuz (see more) within a short distance.
