Caminito del Rey, located near Ardales, Andalusia, Spain, is a dramatic walkway pinned along the steep walls of a narrow gorge. Originally built for workers at a hydroelectric plant, it has been restored and is now a popular, but not fully accessible, tourist attraction. The path is about 7.7 km long, with the walkways portion being approximately 2.9 km. It's generally safe, but not recommended for those with a fear of heights. While solo visits are possible with pre-booked tickets, guided tours are available and can enhance the experience with historical and geological insights. Tickets must be purchased in advance online, and seasonal restrictions or closures may apply due to weather conditions. The cost of entry is typically around €10-€20, and a typical visit, including transportation and the walk itself, can take approximately 4-5 hours. Shuttle buses are used to return visitors to their starting point after they complete the route.
