A Pucker-Upper

A trip up along a very steep mountainside on a walkway called Caminito del Rey near Malaga, Spain. Originally built in 1921, here is more from Wikipedia:

The walkway has now gone many years without maintenance, and is in a highly deteriorated and dangerous state. It is one meter (3 ft) in width, and is over 700 feet (200 m) tall. Nearly all of the path has no handrail. Some parts of the walkway have completely collapsed and have been replaced by a beam and a metallic wire on the wall. Many people have lost their lives on the walkway in recent years. After four people died in two accidents in 1999 and 2000, the local government closed the entrances. However, adventurous tourists still find their way into the walkway.
