Wadi Asimah is a seasonal watercourse in the Hajar Mountains of Ras Al Khaimah in the United Arab Emirates.

A popular location for day trippers and offroading, Wadi Asimah is notable for its lush greenery and agriculture.

[1] It is the site of the 'Sultan's Gardens', an area of abundant oleander, grasses, palm groves and pools that often (and unusually) harbours water year-round, as well as providing a nesting ground for heron.

[2] In winter, the mountainous wadi will receive heavy rainfall, leading to flash floods, and has even seen hail on occasion.

Prehistoric incised arrowheads have been found in the area,[7] which is also the site of an Umm Al Nar settlement, with finds including a bronze goblet, socketed spear-heads and dagger blades.
