Rio de Los Angeles State Park is located on what was once an abandoned freight-switching yard on the east bank of the L.A. River. It sits on a spit of flatland across the river from Elysian Valley and below the hillside bungalows of Mount Washington. Part of the city's river revitalization project that aims to reclaim the postindustrial landscape for green space, Rio de Los Angeles has 47 acres of baseball diamonds, batting cages, soccer fields and basketball and tennis courts, plus a nature trail that unwinds through native flora like a backyard path. There is a playground for the kiddos, with sprinkler fountains that offer refreshment on a hot day. The recreation center hosts classes of yoga, zumba and children's ballet.
