The rocks consist of compressed volcanic ash that dates back to the Paleogene period.
The formation's unique color is caused by the oxidation of manganese and iron minerals within the tuff.
Local geological studies suggest the site was formed during the volcanic activity of the Rhodope massif 40 million years ago.
The structures are scientifically categorized as 'hoodoos' or 'earth pyramids'.
The Stone Wedding is a natural rock formation located near the village of Zimzelen, approximately 3 kilometers from Kardzhali. These rhyolite tuff formations were created by underwater volcanic activity followed by millions of years of erosion. The structures reach heights of up to 10 meters and feature distinct red, pink, and white color palettes due to the presence of metal oxides. The pillars are shaped by the varying hardness of the rock layers, which erode at different speeds. The site remains a geological monument protected by the Bulgarian state since 1974. It is part of the Eastern Rhodope Mountains' broader volcanic landscape.
The elevated path on the northern side offers a full panoramic view of the entire cluster of formations.
Wear sturdy hiking shoes, as the ground consists of loose gravel and uneven terrain.
Bring a hat and sunscreen, as there is almost no natural shade near the formations.
Visit during the golden hour to capture the distinct coloration of the tuff.
Do not attempt to hike the immediate perimeter in open-toed sandals or flip-flops.
Do not climb or deface the rock formations, as they are fragile and legally protected.
