Wonderful Bridges: A Guide to Bulgaria's Natural Rock Arches
The Wonderful Bridges, known locally as Chudnite Mostove, are two dramatic natural arches carved by a river in the heart of the Rhodope Mountains.

Tucked deep in the Rhodope Mountains of southern Bulgaria, the Wonderful Bridges are a geological marvel that feels almost too perfect to be natural. Known as Chudnite Mostove in Bulgarian, these two massive rock arches were formed by the patient work of the Erkyupriya River, which carved its way through a marble ridge over millennia. Today they stand as one of the country's most photogenic and accessible natural wonders.
What Are the Wonderful Bridges?
The Wonderful Bridges are actually the remains of a collapsed cave. Over time, water eroded the softer rock, leaving behind two broad arches that span the river gorge. The larger bridge is about 45 metres wide and rises nearly 30 metres above the stream below, while the smaller one is lower and easier to climb onto. Both are covered in moss and ferns, giving them a lush, almost enchanted appearance. The river still flows beneath them, and in spring the water level rises, turning the area into a rushing torrent.
Getting There
The site lies about 80 kilometres south of Plovdiv and roughly 30 kilometres northwest of Smolyan, in the Central Rhodopes. The most common route is by car: from Plovdiv, follow the road towards Pamporovo, then turn towards the village of Zabardo. The last section is a well-maintained mountain road with signposts to Chudnite Mostove. A parking area sits a short distance from the bridges, and from there a gentle, signposted trail leads into the forest. The walk takes around 15 to 20 minutes, making it suitable for most visitors, including families.
Exploring the Arches
A marked trail loops through the forest and offers several viewpoints, but the real highlight is walking across the smaller bridge. Its flat, wide top is safe enough for a careful stroll, and from there you can peer down into the gorge where the river disappears into a cave. The larger bridge is more impressive from below, where its curved underside frames the sky like a stone rainbow. The trail is not difficult, but sturdy shoes are recommended, as the rocks can be slippery in wet weather.
Best Time to Visit
The Wonderful Bridges are beautiful in every season. In spring, the river swells with snowmelt, and the forest bursts into green. Summer offers warm, dry days ideal for hiking, though the site can get busy at weekends. Autumn brings a blaze of colour to the surrounding beech and pine trees. In winter, the arches are often dusted with snow, and icicles form along the rock walls—though the road may be icy and extra caution is needed. There are no entrance fees or opening hours, and the site is accessible year-round during daylight.
Practical Tips
Bring water and a snack, as there are no cafés or shops at the parking area. The nearest village with amenities is Zabardo, a few kilometres away. If you are staying in the region, the town of Chepelare is a good base, with hotels and restaurants about 20 kilometres east. For a longer day out, combine the visit with the nearby Shiroka Laka architectural reserve or the popular ski resort of Pamporovo. The Wonderful Bridges are a reminder that nature can be both playful and monumental—and they make for an unforgettable stop on any Rhodope itinerary.
