What makes Prohodna Cave called the 'Eyes of God'?

Two enormous natural openings in the cave's ceiling allow sunlight to stream through dramatically, creating an almost cathedral-like illumination. These twin skylights resemble watchful eyes, earning the cave its poetic local name.

How much walking and climbing is involved?

Expect moderate walking across cave galleries and passages (Saeva Dupka spans 400 metres across five galleries) and uneven terrain. The ostrich farm visit is casual. Sturdy shoes with good grip are essential; the caves are not wheelchair-accessible.

Is this suitable for children?

Yes, this is family-friendly. Children typically enjoy the cave exploration and ostrich farm interaction. However, very young children may find long cave walks tiring; confirm suitability for your child's age and fitness level.

What is the Blue Ostrich Farm?

Located in Brestnitsa village, this is Bulgaria's unique ostrich farm where visitors can learn about ostrich breeding, behaviour, and farm life. It's a brief but memorable stop that breaks up the day and offers a distinctive cultural experience.

Why is the transport eco-friendly, and does it affect the tour quality?

Tours use CNG-engine or electric vehicles to reduce air pollution and environmental impact. This doesn't compromise comfort or safety—modern eco-friendly vans are as spacious and reliable as conventional ones, and private transport means a more personalised experience.

Wear sturdy, closed-toe hiking shoes, layer clothing (caves are cool year-round), and bring water, snacks, sun protection, and a camera. A headlamp or torch is optional but useful for detailed cave photography.

About this activity

Explore three extraordinary natural attractions in a single day: the cathedral-like Prohodna Cave with its dramatic 'Eyes of God' skylights, the intricate passages of Saeva Dupka, and Bulgaria's unique Blue Ostrich Farm. This private 9-hour journey combines geological wonder, wildlife encounters, and scenic countryside immersion from Sofia.

After the pick-up in Sofia around 9:00 AM, head to Saeva Dupka, with 400 meters of corridors and 5 galleries. Explore the hidden wonders of one of the strangest caves in Bulgaria.

On your way to the first cave visit "The Blue Ostriches" (Village of Brestnitsa) ostrich farm and learn a little bit more about the life and times of Bulgarian ostriches.

Move on to Prohodna cave, currently the most famous cave in Bulgaria. See how it is naturally illuminated by two huge openings in the ceiling, inspiring the cave's local name, Eyes of God Cave. Explore the entrances, including a 45-meter entrance, the largest in Bulgaria. The expected return to Sofia is at about 6 pm.

Most times the trips are done with eco-friendly cars - with CNG engines or electro mobiles so that we can help fight the air pollution.
