The Todgha Gorges are a series of limestone river canyons, or wadi, in the eastern part of the High Atlas Mountains in Morocco, near the town of Tinerhir.Both the Todgha and neighbouring Dades Rivers are responsible for carving out these deep cliff-sided canyons, on their final 40 kilometres (25 mi) through the mountains. The height of the canyon walls can vary, but in some places can be up to 400 metres (1,312 ft) high
The last 600 metres (1,969 ft) of the Todgha gorge are the most spectacular. Here the canyon narrows to a flat stony track, in places as little as 10 metres (33 ft) wide, with sheer and smooth rock walls up to 160 metres (525 ft) high on each side.
During the dry season, the canyon floor is mostly dry; at most there will be a small stream of water. During this time, the wadi floor is easily traversed by travelers. During the rainy season, however, the Todra can expand massively, covering the canyon floor in a strong torrent.
The area is no longer as remote as it once was. A well-maintained asphalt road leads up the valley from Tinerhir to the gorge. A concrete road continues up the valley, past the hotels at the mouth of the gorge all the way to the villages of Aït Hani, and Tamtatouchte.
Thanks to its robust rock sides with many uneven surfaces, Todgha Gorge is popular among rock climbers. More than 150 routes rated French Grade 5+ to 8 have been bolted in the canyon
