The colour of the river at horse shoe bend, near Page, Northern Arizona,is an unreal shade of green. Be aware – if you walk to the edge from the parking area in the summer it is a HOT walk, but well worth it. It is sandy so footwear may pose a problem. If you wear trainers or enclosed shoes they will get full of hot sand. If you wear flip flops you will probably end up doing a silly hot coals dance!
