Wadi Al Helo is best combined with Hatta and Malhelo as you are heading to the southeast and almost hitting Oman on the way. The problem for my visit was that the area is under heavy construction in 2024. It's hard to see much beyond the nice town that was built up on the mountain. There's not much to be seen in terms of copper production and even if there was I don't think the copper production counts as unique and overwhelming that I would inscribe it as a site. I think in general the sites in the UAE need a bit higher standards, I know they exist, and nobody should be afraid to propose sites that include cultural heritage. Just seeing some copper extraction from who knows when doesn't make it worth seeing.

If you do make it here you'll be funnelled onto the valley top to see the nice town and look below where you just see road and rocks. Not quite the tourist spot I would expect. The good news was the road back to Dubai was through the mountains and quite interesting.
