Most of the path on the Caminito del Rey (above) consists of rickety wooden planks and is barely a metre wide. It is supported by steel rails, which have deteriorated over the years. Although few of the original handrails remain, a safety wire runs along the side. The local council is currently trying to refurbish the walkway, and it is hoped it will be made safe for visitors by 2015 – although it is unlikely that anything will detract from the hair-raising drop below.
