If you’re hunting for a full day of adventure that takes you beneath Bulgaria’s surface, this tour might just be what you’re after. It promises to show you three of the most popular and captivating caves in Bulgaria — Saeva Dupka, Prohodna, and Devetashka — all in one day. The reviews suggest it’s a highly-rated experience, and after looking into what it offers, it’s easy to see why.
We love that this tour combines natural beauty with engaging stories and that it’s designed for small groups. It’s a chance to see some of Bulgaria’s underground marvels without the hassle of planning multiple visits or dealing with big crowds. Plus, the guides seem genuinely knowledgeable and friendly — a big plus for any trip.
That said, a potential consideration is the long day’s drive and walk — so if you’re not into extensive walking or have mobility issues, it’s worth thinking about.

If caves fascinate you or you’re keen to explore Bulgaria’s lesser-known sights, this could be a memorable highlight of your trip.

The Itinerary: What You’ll Experience
Your day begins with a pickup from Sofia around 8:00 AM. From there, the journey takes you into the Vratsa Province, where the caves are located. The first stop is Saeva Dupka, a cave that offers around 400 meters of corridors and five galleries. We loved the way the tour includes a thorough exploration of Saeva Dupka’s features — from stalactites and stalagmites to sinter lakes and draperies. The highlight, according to reviews, is the Harmana gallery with its unique acoustics and the largest stone column in Bulgaria.
Next, you’ll head to Prohodna, perhaps Bulgaria’s most famous cave, easily recognized by its iconic “Eyes of God” openings in the ceiling. This natural marvel is especially striking because of how sunlight streams through the two enormous holes, creating a surreal atmosphere. The cave’s 45-meter entrance is the largest in Bulgaria, and many visitors are captivated by the visual symmetry and the spiritual vibe.
Finally, the trip takes you to Devetaki Cave, a 2442-meter-long and 60-meter-high marvel. It’s known for its picturesque scenery and has been used in movies and Cold War stories. The cave’s walls tell stories of Bulgaria’s past, and it’s designated a monument of culture, adding an extra layer of significance to your visit.
What Makes Each Stop Special?
Saeva Dupka is a true underground maze — a perfect stop for those who love exploring caves with intricate chambers and impressive formations. The guided tour here is detailed, with explanations of the natural features and the chance to stand in awe of Bulgaria’s largest stone column.
Prohodna is a different kind of experience. It’s visually stunning and almost otherworldly. The natural “Eyes of God” openings are best appreciated in good weather when the sunlight hits just right, but no matter the conditions, the imposing size and natural beauty make it worth the visit. From reviews, visitors loved how guides provided insights and helped them appreciate the geological and even spiritual significance.
Devetaki offers a more picturesque, fairy-tale atmosphere. Its size and beauty, combined with the stories from Bulgaria’s Cold War era and Hollywood, make it both fascinating and photogenic. Its status as a cultural monument adds an educational element to the adventure.
The Guides: Knowledge, Friendliness, and Extra Tips

One of the most praised aspects of this tour is the guides’ expertise and personable attitude. Reviews highlight guides like Maria, Mihail, Daniel, and Theodosius, noting their ability to share interesting facts, translate from official park guides, and answer questions. Many reviews mention how guides stayed with the group, provided helpful tips for photos, and made the long drive enjoyable.
For example, a reviewer described their guide as “exceptional, really lovely,” and another mentioned how the guide translated and explained features during Saeva Dupka’s official tour. It’s clear that the guides aren’t just there to show you around — they’re eager to share stories and enhance your understanding of what you’re seeing.

The air-conditioned vehicle and the pick-up/drop-off service make the logistics smoother. Starting at 8:00 AM and lasting about 10 hours, the tour is a full day, but most reviews suggest the length is manageable, especially with the guides’ friendly approach.
Travelers appreciate the small group size, which fosters a more intimate experience and makes it easier to ask questions or take photos without feeling rushed. The flexibility of booking with “reserve now, pay later” and the option to cancel up to 24 hours in advance adds a layer of convenience.
Price and Value
While the exact cost isn’t listed here, the reviews consistently praise the value for money. Included in the price are entrance fees, transportation, an English-speaking guide, and insurance, which means you’re not hit with unexpected costs along the way.
Considering the quality of sights, the expert guides, and the full-day experience, many travelers find the price reasonable. It’s a compact way to see significant natural and cultural sites without worrying about transportation or logistics.
Final Thoughts: Is This Tour for You?
If you’re someone who loves natural wonders, caves, and a bit of adventure, this tour probably hits the right notes. The stunning geological features combined with the friendly guides and small group size make for a memorable day. It’s ideal for travelers who want a balanced mix of sightseeing and education, with enough flexibility to ask questions and take photos.
This experience is less suited for those who prefer leisurely, relaxed days or have mobility constraints, as the cave explorations involve walking and some uneven terrain. Also, keep in mind that the tour includes a long drive, so if you’re prone to travel fatigue, be prepared.
This day trip offers a unique glimpse into Bulgaria’s underground beauty, making it a worthwhile addition to your Bulgaria itinerary. Whether you’re a geology buff, a history lover, or just someone seeking breathtaking views, you’re likely to find this tour both engaging and rewarding.
