Devetashka Cave: Where Sunlight Streams Through Stone Eyes

The air changes the moment you step inside—cooler, damper, heavy with the scent of limestone and history. Before the entrance, which yawns 35 meters wide and 30 meters high, you pause . Then you enter, and the cave swallows you into its cathedral-like silence. Above, seven massive openings in the ceiling—the "okna" or "eyes" that give the cave its local name—allow shafts of sunlight to pierce the darkness, illuminating the vast interior like natural spotlights from heaven . This is Devetashka Cave, a 2-kilometer-long karst wonder in northern Bulgaria, a place where the ceiling soars to 100 meters in height and where humans have sought shelter for 70,000 years . Recognized as one of the 100 Tourist Sites of Bulgaria and declared a natural monument in 1996, this is not merely a cave—it is a time capsule of human civilization, a sanctuary for 30,000 bats, and a Hollywood film set where Sylvester Stallonce once crash-landed a plane into Jean-Claude Van Damme's subterranean lair .

Why Devetashka Embodies Bulgaria's Natural and Human Heritage

The story of Devetashka Cave stretches back 70,000 years to the Middle Paleolithic era, when the first humans sought refuge within its massive halls . Archaeological excavations in the 1950s—initially conducted to explore converting the cave into a state warehouse—revealed almost continuous human occupation across millennia . The site has yielded one of the richest collections of Neolithic artifacts in Bulgaria, dating from the 6th to the 4th millennium BC . Today, the cave serves a different master: nature. It is one of the three most important bat habitats in all of Europe, home to 15 species of bats and a population of approximately 30,000 individuals . During the breeding season from early June to the end of July, the cave closes entirely to protect these winged residents . The surrounding area hosts 12 protected species of amphibians and reptiles, 82 bird species, and 34 mammal species, making the Devetashka Plateau a biodiversity hotspot of European significance .

The Best Time to Experience Devetashka Cave

Timing your visit requires balancing human access with bat protection. The cave operates on a seasonal schedule: open to visitors from August 1 through May 31, with a mandatory closure from June 1 through July 31 for the bat breeding season . The best months for visiting are August through October, when daytime temperatures in the Lovech region average 20°C to 25°C (68°F to 77°F), and the cave interior maintains a constant cool temperature of approximately 12°C to 15°C (54°F to 59°F)—bring a jacket regardless of the season. For photographers, the magic hours inside the cave are 10:00 AM to 2:00 PM, when the sun is high enough to send dramatic shafts of light through the seven ceiling openings, illuminating the emerald pools and ancient stalactites . May and September offer pleasant weather (average 22°C / 72°F) and smaller crowds compared to August. Avoid visiting during the closed season (June–July) unless you are content to view the entrance from outside; the closure is strictly enforced to protect the 30,000 bats rearing their young.

7 Essential Devetashka Cave Experiences

1. Watch the Sunbeams Illuminate the "Eyes": The defining experience of Devetashka is witnessing sunlight pour through the seven ceiling openings. These natural skylights—locally called "oknata"—create shifting columns of light that move across the cave floor throughout the day . For the most dramatic effect, visit between 10:00 AM and 2:00 PM, when the sun is at its highest. The beams illuminate the emerald pools formed by the small river that runs through the cave, creating a scene of almost supernatural beauty .
2. Cross the "Expendables 2" Bridge: As you approach the cave from the parking area, you will cross a concrete bridge over a small tributary of the Osam River. This bridge was constructed in 2011 specifically for the filming of Hollywood blockbuster "The Expendables 2" . In the film, Sylvester Stallone's character crash-lands a plane into the cave—Jean-Claude Van Damme's villainous lair. The bridge remains as a quirky cinematic monument .
3. Explore the Two Branches of the Cave: Approximately 200 meters from the entrance, the cave splits into two distinct branches . The left branch follows the underground river, forming miniature lakes and small waterfalls that eventually flow into the Osam River. The right branch is warm and dry, leading to several chambers and ending in a round hall known as "The Altar," adorned with beautiful stalactites and stalagmites . Both branches offer unique atmospheres—choose based on your time and comfort level with uneven terrain.
4. Marvel at the Stalactites and Stalagmites: Devetashka is rich in speleothems—mineral formations created over millennia. Look for majestic natural domes, limestone arches, and countless rivulets carving their way through the rock . The cave's vast scale means these formations often go unnoticed by visitors focused on the sunbeams; take time to examine the walls and ceilings where stalactites hang like stone icicles.
5. Search for the Cave's Bat Residents (From a Distance): Devetashka is one of Europe's most important bat habitats, home to 15 species and approximately 30,000 individuals . During the open season (August–May), you may spot clusters of bats hanging from the highest ceilings or swooping through the main hall at dusk. Do not disturb them with flash photography or loud noises. If you visit in late August, you might witness the young bats taking their first flights—a spectacular natural event.
6. Combine with Krushuna Waterfalls (15 Minutes Away): The Krushuna Waterfalls, a protected natural reserve featuring turquoise cascades and travertine pools, lies just a 15-minute drive from Devetashka Cave . The waterfalls tumble over limestone cliffs, creating a series of natural pools perfect for photography. In medieval times, hermit monks lived in cells carved into the rocks above the roaring waters . A combined day trip—morning at the cave, afternoon at the waterfalls—is the classic Devetashko Plateau experience.
7. Descend into Garvanitsa Abyss (For Adventurers): A short drive from Devetashka, near the village of Gorsko Slivovo, lies Garvanitsa Cave—a dizzying 60-meter (197-foot) vertical abyss . A metal ladder allows visitors to descend to the bottom and experience the "icy breath of eternity." This is not for those with a fear of heights, but the reward is a perspective on karst geology that the main cave cannot offer. The site is less visited than Devetashka, meaning you may have the abyss to yourself.

3 Hidden Gems Most Travelers Miss

• Stalbitsata (The Ladder Cave): Also known as the Ladder Cave, this hidden gem requires descending an almost vertical ladder to access a chamber of majestic dome-shaped stalagmites and a rare sinter lake . The cave is unmarked on most tourist maps; ask locally in the village of Gorsko Slivovo for directions. The ladder is sturdy but exposed—wear grippy shoes and consider using both hands. The sinter lake, a shallow pool of crystal-clear water with mineral formations growing from its bottom, is unique in the region and photographed by almost no one.
• The Hermit Cells Above Krushuna Waterfalls: Most visitors photograph the Krushuna Waterfalls from the tourist path. Few climb the steep, unmarked trail to the right of the main cascade, which leads to rock-hewn cells where medieval hermit monks lived in isolation . The cells are small, barely 2 meters by 2 meters, with carved windows overlooking the falls. The climb takes 15 minutes and requires scrambling; the reward is a profound sense of solitude and a view of the waterfalls that no other tourist will capture.
• Devetaki Village's Traditional Lunch Experience: The village of Devetaki, located 2 kilometers from the cave, is bypassed by most tour groups . But several families in the village offer traditional Bulgarian lunches in their homes—a "meal with a local" experience that requires no advance booking (just knock and ask, using the phrase "obed, molya" for "lunch, please"). For 10–15 BGN per person, you will be served homemade shopska salad, freshly baked bread, grilled meat, and the family's own rakia (grape brandy). This is not a commercial restaurant; it is Bulgarian hospitality at its most authentic, and the grandmothers will be delighted to feed you.

Cultural & Practical Tips

• Respect the bat closure: The cave is entirely closed from June 1 through July 31 for bat breeding . Do not attempt to enter during this period—the closure is enforced by park staff, and disturbing the bats carries legal penalties. Plan your visit for August through May.
• Nodding means NO: Bulgaria shares the famous head gesture quirk with Greece. A nod up and down means "no." A side-to-side shake means "yes." If uncertain, use "da" (yes) and "ne" (no) verbally.
• Phrases to learn: "Zdravete" (ZDRA-ve-te) — hello. "Blagodarya" (bla-go-DA-rya) — thank you. "Peshterata" (PESH-te-ra-ta) — the cave. "Prilepi" (PREE-le-pee) — bats. "Kolko struva vhodut?" (KOL-ko STRU-va VHO-dut?) — how much is the entrance?
• Wear appropriate footwear: The cave floor is uneven, with loose rocks, mud, and standing water in places. Sturdy hiking boots or waterproof walking shoes are essential. Sandals or flip-flops are dangerous and not recommended . The path from the parking area to the cave entrance is rough in parts, and the interior paths are unmaintained beyond basic walking surfaces.
• Bring a jacket (even in summer): The cave maintains a constant cool temperature of approximately 12–15°C (54–59°F), regardless of outside heat. A light fleece or jacket is essential, especially if you plan to spend more than 30 minutes inside .
• Photography guidelines: Flash photography can disturb the bats, especially during daylight hours when they are resting. Use high ISO settings and a tripod for low-light interior shots instead of flash. The best photographs are taken between 10:00 AM and 2:00 PM, when sunbeams create natural lighting effects . No drones inside the cave (disturbs bats and is prohibited).
• Cash is preferred at the cave entrance: While some operators accept cards, the cave entrance fee is typically collected in cash (2–2.50 EUR or 4–5 BGN) . The small kiosk has limited change, so bring small bills. Parking is usually free .
• Combine with Lovech: The historic city of Lovech, known for its covered bridge (Krivata Most) designed by Bulgarian architect Kolyo Ficheto in the 1870s, is just 15 km from the cave. The Lovech Fortress (Varosha) offers panoramic views of the Osam River valley. Most visitors to Devetashka spend a half-day at the cave and waterfalls, then the afternoon exploring Lovech's old town.

Conclusion: Travel with Silence, Not Just Shutter Clicks

You could walk into Devetashka, photograph the sunbeams, and walk out in twenty minutes. Many do. Or you could do what the cave asks of you: slow down. Stand beneath one of the seven "eyes" and watch the column of light shift across the stone floor as the minutes pass. Listen to the drip of water from a stalactite—a rhythm unchanged for millennia. Notice the bats hanging thirty meters above, sleeping through your presence, heirs to a home humans abandoned but never improved. Devetashka does not perform on demand. It offers no light shows, no electrified pathways, no recorded commentary. Its story—70,000 years of human and animal habitation—is written in the limestone itself, in the Neolithic artifacts now housed in museums, in the Hollywood bridge that seems almost absurd against this ancient backdrop. The best way to honor that story is not to capture it but to witness it. To be still. To let the cool air settle on your skin. To leave as silently as you arrived, carrying no rock, no echo, no memory but the one the cave gives freely: that some places deserve not your camera, but your quiet awe.
