The wadi is a 'y' shaped waterway, one branch passing through the villages of
Harrah and Wadi Helo, while the other runs down from the Wadi Helo lagoon, located further along the old Sharjah-Kalba highway towards
Kalba. The new highway opened in October 2020, runs 26km from Wadi Helo to Kalba. The two branches of Wadi Helo meet west of the village of Awhala and the wadi passes through Awhala and beside the historic
Awhala Fort before crossing the
Omani border and fanning out to the
Batinah plain and the
Gulf of Oman north of the Omani coastal village of Bu Baqarah. The lower reaches of the wadi are lined to either side with a number of pre-Islamic burials. Wadi Helo is traditionally home to the
Mazari tribe and was a wealthy tobacco growing centre. Today the upper reaches of the wadi are dotted with hundreds of abandoned stone-lined tobacco plantations. Villagers from the village of
Hayl would travel to Wadi Helo seasonally to take part in harvesting the tobacco crop, which would be sold to local traders in
Fujairah and
Sharjah. == World Heritage Site ==
