The Draa Valley
The Draa also spelled Dra or Drâa, in older sources mostly Darha or Dara), is Morocco's longest river, 1,100 kilometres (680 mi). It is formed by the confluence of the Dadès River and Imini River. It flows from the High Atlas mountains south-(east)ward to Tagounit and from Tagounit mostly westwards to the Atlantic Ocean somewhat north of Tan-Tan. Most of the year the part of the Draa after Tagounit falls dry.
The Todgha Valley
Todgha Gorge is a canyon in the eastern part of the High Atlas Mountains in Morocco, near the town of Tinghir. Both the Todgha and neighbouring Dades Rivers have carved out cliff-sided canyons on their final 40 kilometres (25 mi) through the mountains. 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.
The Dades Valley
Dadès Gorges is a canyon of the Dadès River and lies between the Atlas Mountains and the Jbel Saghro of the Anti-Atlas mountain range, in Morocco. Berbers built many kasbahs in vicinity of gorges with defence purposes. These many kasbahs together with the natural beauty of the place have contributed to make it a tourist attraction in recent years.
