The Rio Hondo River Trail - Garfield Avenue N Connector is a short trail which provides access to the Rio Hondo River Trail. This multi-use trail runs parallel to Rio Hondo through the San Gabriel Valley. The northern end starts along the reservoir at the Peck Road Water Conservation Park and follows along the channel to Whittier Narrows Recreation Area. Connect to the San Gabriel River Trail here or continue on south to the trail along the lower portion of the Los Angeles River. The Rio Hondo River Trail is a popular bicycle route and it is important to be mindful of all trail users.

To access the northern trailhead in El Monte, follow Peck Road to the intersection with Rio Hondo Parkway. Peck Road Water Conservation Park is located on the east side of Peck Road. The trail starts just south of the main parking lot for the park.
