Situated along the road from Hambull to Çorovode, Osumi Canyons are the largest canyons in the country referred as the “Grand Canyon” of Albania. The canyons are around 13km long, 4-35m wide, 70-80m deep, and with steep vertical slopes. The edges of the canyon have an unusual ecosystem that preserves the greenery on both sides of the canyon year-round. Mediterranean bushes like heath and briar flourish along with rich flora and fauna. On the slopes of the canyon, erosion has created pockmarked cavern walls with small caves. Some of the rock formations in the canyon have fanciful names such as the Cathedral, the Eye, and the Demon’s Door. The canyons are 26 km (16 miles) long, at an altitude of 450 m. They are thought to have been formed 2-3 million years ago by water erosion.
It is generally thought that many years ago the river flowed underground, but over time the rock above the river disappeared, creating the current form of the canyon. In the gulf of this canyon that passes Osum River in both its sides, water flows come from different villages which pass in a rock chain.
Flowing through the canyon is the playful Osumi River. Large and beautiful waterfalls can be seen in some parts of the canyon which are especially beautiful on the days when the sun rays sparkle over the water, forming rainbows that start from the sky and move down the sides of the canyon until they finally reflect along the riverbeds. Tourists may experience rafting and water activities especially form the end of April until the middle of June.
