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 Dadès Gorges, or Dades Valley are a series of rugged wadi gorges carved out by the Dadès River in Morocco. The river originates in the High Atlas range of the Atlas mountains, flowing some 350 kilometres southwest before joining the Draa River at the edge of the Sahara. The walls of the gorges range anywhere from 200 to 500 meters (650 to 1600 feet).
