Thought to be the second deepest canyon in the world, Valla Canyon and nearby Horma Canyon are practically impassible. A portion of the canyon can be traversed on a three kilometer wooden walkway that is attached to the canyon walls. Several waterfalls can be seen along the way. The canyon is so narrow and deep that the sunlight never reaches some places. The canyons are located in northwestern Turkey north of Kastamonu.
