Bolivians in La Paz have marked the second annual Day of the Pedestrian and Cyclist.
The event sees motor vehicles banned and a festival atmosphere descend on streets normally packed with traffic.
It is hoped the event will raise environmental awareness among Bolivians as well encourage people to explore alternative modes of transport.
