Will I definitely see griffon vultures?

The Blue Stones park hosts one of Europe's largest populations, so sightings are highly likely, especially in morning hours. Your guide knows the best vantage points for observations.

Binoculars, camera/telephoto lens, sun protection (hat, sunscreen), water, snacks, and layers. Sturdy hiking boots are strongly recommended.

Is this tour private?

Yes—it's a private guided experience, so timing, pace, and focus are customised to your interests and group size.

How far is Sliven from major cities?

Sliven is in eastern Bulgaria, roughly 250 km from Sofia and 150 km from the Black Sea coast. Your guide can advise on transport from nearby towns.

What's the best time of year to visit?

Spring (April–May) and autumn (September–October) offer ideal conditions—pleasant temperatures and peak vulture activity. Summer can be hot; winter access may be limited by snow.

our guide Nadia couldnt do enough for us and a little local spot off the usual route was the highlight. Last day of the trip so it wasnt too busy. Worked great for a solo traveller like me, and came away with 200+ photos, and ran the full 4 hours promised. Would book again no question, 10/10
