Saeva Dupka and Prohodna Cave (Eyes of God) from Sofia

All prices are in euro: Bulgaria adopted the euro on 1 January 2026. Our tour price was read from our booking system on 18 October 2026, and the price shown when you book is the one that counts. Saeva Dupka's opening hours and ticket prices are those published on the cave's page by the Bulgarian Tourist Union on the same day. You will also see the names spelled Sueva Dupka and Prohodna Cave; they are the same places.

Saeva Dupka cave: what you see inside

Saeva Dupka is about 400 m long, and what makes it special is how densely its tall, lit halls are packed with stalactites and stalagmites. It sits on a hillside about 2 km from Brestnitsa in Lovech Province, and you can drive almost to the mouth: from the car park to the ticket desk is a walk of about 100 m. Inside there are paths, handrails and lighting, but also steps and changes in level, and the floor is wet in places.

Visits are in groups with a local guide and take 30 to 40 minutes. The temperature inside stays between 7 and 11°C all year and the air is humid, so bring a warm layer even in August. These are the five halls, in the order you visit them:

• Kupena (the Haystack): the hall nearest the entrance.
• Srutishteto (the Collapse): the largest hall in the cave.
• Harmana (the Threshing Floor): famous for its acoustics, which is why concerts, often by choirs, are held here.
• Belia Zamak (the White Castle): a hall of particularly pale formations.
• Kosmos (Cosmos): the last hall on the route.

A little history: local tradition says the name comes from two brothers who hid in the cave during Ottoman rule. It was declared a natural landmark in 1962, opened to visitors in 1967, closed in 1990 and reopened in 2004. When it was prepared for visitors, workers found animal bones, pottery and Roman coins.

Saeva Dupka opening hours and ticket prices

Tickets are sold at the desk by the entrance, and it is wise to carry some cash. If you are arriving close to closing time in winter, or with a large group, call the cave's guides first on +359 888 864 187. Hours and prices change from time to time, so check again before you set off.

Prohodna cave and the Eyes of God

Prohodna is not a dark, closed cave but a huge rock arch: a natural tunnel about 260 m long, the longest cave passage in Bulgaria, open at both ends. The small entrance is about 35 m high and the big one about 42 to 45 m. In the roof of the middle chamber are two openings of almost identical size, carved by water erosion. Stand beneath them and look up, and they look exactly like a pair of eyes gazing down, hence the name Eyes of God. The openings also appear in the 1988 Bulgarian film Time of Violence.

The cave is about 2 km from Karlukovo, beside the road to the town of Lukovit, with a car park near the small entrance. There is no ticket desk, no gate and no opening hours: entry is free and there are no staff. There is no lighting either, so come in daylight. The floor is rocky and uneven, and muddy and slippery after rain, so shoes with good grip are a must. Do not be surprised to see climbers on the walls or bungee jumpers leaping from the arch of the big entrance: Prohodna is a well known climbing and bungee spot. The best photos of the eyes come around midday, when the sun is high.

How to get from Sofia to Saeva Dupka and Prohodna

On a guided day trip from Sofia

Our day trip leaves Sofia at 09:00 and returns at around 17:00 to 17:30. The plan covers the Eyes of God at Prohodna, the stalactite halls of Saeva Dupka and a nature stop by the river. A local guide and transport in a comfortable vehicle are included. Private tours pick you up from your hotel lobby; group tours meet at St Alexander Nevsky Cathedral. The price is €85 per person, children pay the same, and the Saeva Dupka entrance fee is not included. Tours run for 2 to 8 guests, the host confirms each booking, and cancellation is free up to 24 hours before. You pay 20% online and the rest to your host at the end of the tour.

By rental car

With a rental car, drive east from Sofia on the Hemus motorway to Yablanitsa, take the exit towards Lovech and Brestnitsa, and follow the signs on a paved road up to the Saeva Dupka car park. For Prohodna, continue north through Lukovit to Karlukovo. On the way back you can rejoin the motorway or take the slower, scenic road through the Iskar Gorge. For insurance, the vignette and what to check at pickup, see our guide to renting a car in Bulgaria.

By train, Prohodna only

There is no practical public transport to Saeva Dupka. Prohodna can be reached by train to Karlukovo station, but there is no direct service: on Bulgarian Railways' timetable for Monday 19 October 2026, every journey from Sofia involves a change, and the most useful morning train leaves at 07:00 and arrives at 09:39. From the station it is about 3 km on a paved road to the National Caving House and another 1.5 km to the cave. It suits keen walkers with a full day; check trains on the day you travel, as engineering works change the timetable.

A Saeva Dupka and Prohodna day trip: sample itinerary

1. 09:00, leave Sofia: an hour and a half east on the motorway.
2. Around 10:30, Saeva Dupka: a 30 to 40 minute guided tour, plus time for a coffee outside.
3. Around 12:30, lunch: in one of the small towns on the way, near Yablanitsa or Lukovit.
4. Around 14:00, Prohodna: an hour inside the arch and under the eyes, in the afternoon light.
5. Around 15:30, head back: you are in Sofia at about 17:00 to 17:30.

Treat this as a sample. On our tour the order of stops may differ, and you settle the details with your host. If you want the eyes with the sun high, you can also start at Prohodna and finish at Saeva Dupka, which stays open until 17:00 in winter.

Saeva Dupka and Prohodna in winter

Both caves are open in winter. Saeva Dupka runs from October to March from 09:00 to 17:00, with the last group going in at 16:30. What changes is the drive: the Bulgarian Tourist Union warns on the cave's page that in winter conditions the road up is difficult to pass. In winter, drive only on winter tyres and check road conditions with Bulgaria's Road Infrastructure Agency before you leave.

At Prohodna, think about daylight. In mid December the sun sets at Karlukovo at around 16:50, so plan to be there by 15:30 at the latest. On freezing days, water dripping from the roof turns to ice near the entrances, so take it slowly there. Inside Saeva Dupka, by contrast, the temperature barely changes through the year, which makes it a good plan for a cold or rainy day. For more ideas for these months, see our guide to Bulgaria in winter.

Saeva Dupka and Prohodna with kids

This day trip works well with children. At Saeva Dupka, under 7s go free and under 18s pay €3. The tour is short, and children usually love the stalactites and the lit halls. On the other hand, there are steps and wet floors, so a pushchair will not get through: a baby carrier is better. Give children a warm layer, as 7 to 11°C feels cold after a few minutes. Prohodna is open, rocky ground, so keep little ones close, especially near the big entrance. On our tour children pay the adult price, and the host does not recommend it during pregnancy. For more family ideas, see our guide to Sofia with kids.

More in the area: Karlukovo, Lukovit and the Iskar Gorge

Prohodna is part of the Iskar Panega Geopark, a large karst area around Lukovit, and the Karlukovo area alone has nearly 400 caves and potholes. If you have time left, these are the stops worth making:

• National Caving House: a building near Prohodna that serves as a base for cavers. The path to the big entrance starts here.
• Karlukovo Monastery: the Monastery of the Dormition of the Mother of God, about 45 minutes' walk from the Caving House, with a few small rock churches nearby.
• The Iskar Gorge: if you drive back to Sofia through the gorge instead of on the motorway, you pass the Lakatnik rocks. The road is slow and beautiful. In summer, April to September, there is rafting on the Iskar river near Lakatnik.

Other caves in Bulgaria, such as Yagodinska and the Devil's Throat in the Rhodopes, are a different trip with an overnight stay. If you are choosing between several outings from the capital, read our guide to day trips from Sofia, and browse all our day trips from Sofia.

What to bring

• Closed shoes with a grippy sole, for both caves.
• A sweater or light jacket, even in summer, for Saeva Dupka.
• Cash for tickets and a coffee at the car park.
• Water and a snack, as there are almost no facilities at Prohodna.
• In winter: gloves, and a small torch if you linger at Prohodna towards sunset.

If you would rather spend the day without driving, parking or guessing the order of stops, our guided tour takes you to both caves and has you back in Sofia before evening.
