Every August 1, half of Costa Rica drops to their knees or straps on their walking boots for the pilgrimage to the Basilica de Nuestra Señora de los Angeles in Cartago.

A Catholic tradition that harks back to the 17th century, devotees walk or crawl from all points in the country to honour or seek the healing powers of La Negrita - a statuette of a black Virgin Mary that is Costa Rica's patron saint.

Nothing screams Costa Rica more than a strapped-in tourist screaming their way across a rainforest canopy.
