Devetashka Cave & the Lovech Karst: Bulgaria's Cave Country
In this guide▾
North-central Bulgaria doesn't shout for attention — but hidden in the limestone plateau around Lovech is some of the country's most spectacular scenery, carved entirely by water. Over millions of years the rivers here have hollowed out caverns, hung terraces of turquoise pools and punched skylights through solid rock, leaving a cluster of natural wonders within a short drive of one another. Three of them — a colossal cave, a turquoise waterfall staircase and a cave roof pierced like a pair of eyes — make one of the best day trips in the country.
This guide covers the Lovech karst trio: Devetashka Cave, the Krushuna Falls and Prohodna Cave, and how to string them together.
📍 Orientation: Cave Country Around Lovech
The old town of Lovech — with its covered bridge and Balkan-revival houses — is the natural gateway. From here the karst spreads north and west: Devetashka Cave and the Krushuna Falls cluster together to the northeast above the Osam River, while Prohodna Cave lies to the west near Karlukovo. None is more than an hour apart, so the whole trio fits into a single loop.
🕳️ Devetashka Cave
The showpiece is Devetashka Cave, one of the largest caves in Bulgaria and a genuinely awe-inspiring space. Its enormous entrance opens into a cavern so big that huge holes in the roof flood the interior with shafts of daylight, illuminating an underground river and pools far below. People have sheltered here since prehistoric times, and today it shelters a colony of tens of thousands of bats.
Devetashka's drama has made it a film star — it stood in as a location for international productions, including a Hollywood action film — but nothing on screen matches standing under those pillars of light in person. Note that access is restricted during the bat breeding season (roughly summer) to protect the colony, so check the current rules before visiting.
💧 Krushuna Falls
A few kilometers away near the village of Krushuna, the Krushuna Falls are the largest waterfalls in Bulgaria — a staircase of turquoise travertine pools spilling down a forested hillside. A trail climbs alongside the cascades to the source, past mossy terraces and vivid blue-green water that keeps its colour thanks to the mineral-rich flow.
It's an easy, beautiful walk and pairs perfectly with Devetashka just up the road — for the wider context of the country's headline natural sites, see our Bulgaria natural wonders guide. We've also got a dedicated Krushuna Falls guide with the trail details.
👁️ Prohodna Cave — the "God's Eyes"
To the west, near Karlukovo, Prohodna Cave is a through-cave famous for two eye-shaped holes in its ceiling — the "Eyes of God" (Oknata) — that stare up at the sky and, depending on the light and weather, seem to weep. It's a short walk from the road, free to enter, and a magnet for photographers and rock climbers alike. Our Prohodna Cave guide has the full story.
🗺️ Doing It as a Day Loop
From Lovech (or as a long day from Sofia), the natural circuit is:
- Krushuna Falls → Devetashka Cave (close together, northeast of Lovech), then
- Prohodna Cave to the west near Karlukovo on the way back toward Sofia.
- Allow an hour or so at each, plus a stop in Lovech for the old town and covered bridge.
- Wear proper shoes — the Krushuna trail and cave floors can be wet and slippery.
- Late spring and autumn are best: full waterfalls, green forest and mild weather.
A flat plateau hiding cathedrals of stone, staircases of turquoise water and windows to the sky — the Lovech karst is one of Bulgaria's great surprises. Follow the water underground, and keep exploring with Mestala.com.

Frequently Asked Questions
Where is Devetashka Cave and how do you get there?▾
Devetashka Cave is about 18 km northeast of Lovech in north-central Bulgaria, near the village of Devetaki above the Osam River. It's roughly a 2.5-hour drive from Sofia. A car is the easiest way to reach it and to combine it with the Krushuna Falls and Prohodna Cave nearby.
Why is Devetashka Cave famous?▾
Devetashka is one of the largest caves in Bulgaria — a vast cavern with huge openings in its roof that send shafts of light down onto an underground river. It has been inhabited since prehistoric times and is home to tens of thousands of bats, and it gained international fame as a filming location, including for a Hollywood action movie.
Can you visit Devetashka, Krushuna and Prohodna in one day?▾
Yes. All three sit within the Lovech karst, a short drive from one another, and make an excellent single day loop. Krushuna Falls and Devetashka Cave are especially close together northeast of Lovech, while Prohodna lies to the west near the village of Karlukovo — a full but very rewarding day.
What are the Krushuna Falls?▾
The Krushuna Falls are a cascade of turquoise travertine pools and waterfalls near the village of Krushuna, the largest in Bulgaria. A walking trail climbs alongside the terraced cascades, and the mineral-rich water keeps its vivid colour year-round — it's one of the country's most photographed natural sites.
Is there an entrance fee, and when is the best time to visit?▾
Some sites charge a small fee or have seasonal access rules — Devetashka Cave, for example, restricts visits during the bat breeding season (roughly June to late summer) to protect the colony, so check before you go. Late spring and autumn are ideal across the karst: green landscapes, full waterfalls and comfortable temperatures.
