The Todra gorge can be easily reached from the city of Tinerhir in southern Morocco. Over the course of time both the Todra and the neighbouring Dades rivers have carved out cliff-sided canyons on their final 40km through the mountains. The narrowest part of the Todra gorge is the most spectacular, as the canyon narrows to a flat stony track as little as 10m wide in places with sheer and smooth rock walls up to 300m high on each side.
