The Rio Hondo River Trail runs for more than 17 miles through Los Angeles County along its namesake waterway, a partially channelized tributary of the Los Angeles River. The trail extends northeast from its junction with the Los Angeles River Trail, which heads north to Vernon and south to Long Beach, to Peck Road Water Conservation Park in Arcadia.
Several neighborhood parks along the way provide opportunities to picnic, play or relax, including Crawford Park in Downey, where a bridge transports trail users over the river, John Anson Ford Park in Bell Gardens, Treasure Island Park in Downey, Veterans Memorial Park in Commerce, Grant Rea Park in Montebello and the trail's northern endpoint at Peck Road Water Conservation Park in Arcadia.
The large Whittier Narrows Recreation Area is perhaps the most scenic element along the trail's route. The popular local destination offers hiking trails, lakes perfect for fishing, and tennis and volleyball courts, among many other amenities. Trail users can also connect to the winding San Gabriel River Trail from the recreation area via a trail spur extending southeast from San Gabriel Boulevard.
Parking is available at several of the local parks along the Rio Hondo River Trail's route, including Crawford Park (7000 Dinwiddie Street) and Treasure Island Park (9300 Bluff Road) in Downey, John Anson Ford Park (8000 Park Lane) in Bell Gardens, Veterans Memorial Park (6364 Zindell Avenue) in Commerce, Grant Rea Park (600 N. Rea Drive) in Montebello and Peck Road Water Conservation Park (5401 N. Peck Road) in Arcadia.
