• Stairs at most viaduct entrances, with elevators at Rue Hector Malot and 34 Rue de Lyon that are sometimes out of service, so check before bringing a heavy stroller
• Toilets and drinking water along the route, but no baby-changing table
• Jardin de Reuilly midway, where the path crosses a footbridge over an open lawn for running around and picnics

Also called the Promenade Plantée, this 4.5 km walkway follows an old railway line from Bastille toward the Bois de Vincennes. One stretch runs on a viaduct above Avenue Daumesnil at treetop height, then the path drops through tunnels and cuttings into the Reuilly gardens.

The arches below hold the Viaduc des Arts, where some craftspeople work in glass-front workshops. It suits a long stroller walk or a slow family ramble.
