The Coloured Canyon rock formations are an incomparable attraction, they vary from sandstone to limestone, granite and veins of basalt dominate the scenery through the entire hike.  it is a geological wonderland. At some places, the rocks radiate crystalline colors, at others, they have a smooth velvety appearance. As the trail continues, the river gets smaller and smaller.The vegetation is very limited – lonely acacias, green capparis , tamarisk trees, willow trees, sodom apples (which are poisonous) and desert pumpkin.
