The San Gabriel River Trail extends from the base of the San Gabriel Mountains all the way to the Pacific Ocean. A key component of Los Angeles County's transportation infrastructure, the trail connects to the Rio Hondo River Trail, Bellflower Bike Trail and Coyote Creek Bikeway, forming the backbone of a huge trail system for the region. An eventual connection to the Whittier Greenway Trail will provide additional recreational and transportation options for residents of that city.
The trail travels through an exceptionally diverse landscape. In the south, the trail follows the channelized river past a mix of industrial and residential surroundings, while the northern portion opens up to scenic vistas of the surrounding mountains. The trail and river—left to its natural course in the north—also passes through scenic protected areas here, including the Santa Fe Dam Recreation Area and Whittier Narrows.
Parking is available at two trailheads in Azusa: a small parking lot is located near the trail's northern end on San Gabriel Canyon Road (State Route 39), while a much larger parking lot can be found off E. Foothill Boulevard.
At the trail's southern end, park at the beach parking lot off 1st Street in Seal Beach. (Note that a parking fee is charged here.)
