Day trip! We’re driving south of Plovdiv to see the Chudnite Mostove (Wondrous Bridges/Marvelous Bridges), Bachkovo Monastery, and Assen’s Fortress, all nestled in the mountains south of Asenovgrad. Here in Bulgaria summer still lingers and sunlight spills over the landscape, sneaking through the trees and dappling the trails. The hot midday air smells like pine sap and cut grass. And the afternoon stretches the shadows long between the steep mountain peaks, bathing us in shade and cool winds. Though it’s the cheapest (and poorest) member in the E.U., Bulgaria has natural beauty to rival any other country.
