The narrow wooden path was closed 14-years-ago following the deaths of five people.
Christened "the world’s most dangerous walkway", El Caminito, which clings to the side of the El Chorro gorge, near Álora in Malaga, is one metre wide and 7.7km long.
The walkway was recently listed as one of the best new attractions of 2015 by The Lonely Planet travel guide.
Local government funding of €2.5 million ($2.6 million) has reinforced the 100 metre-high pathway and added safety measures.
Tickets to walk the path are free, but require advanced booking. Spokesman for Malaga Tourist Board, Gustavo Ballesteros, told The Local that 33,000 tickets had already been reserved.
