Starting form the Sea, Follow the road for the first 10km to the Dam at Wadi Ghalilah.  From here there are markers for the trail head which takes you all the way to the flagpole and then left up towards the "highest zipline".

After a short decent along the side of the road, you will come to the army manned carpark and helipad where the trail runs left up to the UAE summit side.

This route is excellent stacked upon excellent. It is a Red Rocks classic and run-scramblers dream, full of exposed 4th/5th class terrain, handlines, and route finding. (TL;DR: this is not a casual trail run.)

The Rainbow Cirque is a high-traverse around the grand amphitheater created by the Rainbow Massiff tagging 5 key peaks/sub-peaks (each with its own summit register). 

The peaks are as follows:

- Rainbow Peak 

- Rainbow Wall
