The Los Angeles River is 51 miles long and almost entirely concrete. That part most people know. What gets forgotten is that the Army Corps of Engineers left three pieces of the river soft-bottomed in the 1940s, because the groundwater table was too high to pave. The longest of those three pieces is the Glendale Narrows: 11 miles from the north tip of Griffith Park down to Atwater Village, where the river runs in earth, willows grow out of the channel, and great blue herons fish for crayfish in the middle of the second-largest city in America.
This is a guide to the trail along the Glendale Narrows and the small parks that string it together. It is probably the most under-walked good walk in LA.
A 90-second history of why the river looks like this
The 1938 flood killed 115 people in greater Los Angeles and washed out big chunks of east LA. The Army Corps of Engineers was given the river to fix. Over the next decade they lined almost the entire channel in concrete. Three stretches resisted: the Glendale Narrows, the Sepulveda Basin, and the river mouth at Long Beach. The groundwater there sat too close to the surface for concrete to stick.
For sixty years after that, the river was a utility. Nobody walked next to it on purpose. In 1985 the poet Lewis MacAdams co-founded Friends of the LA River, held a guerrilla ceremony to declare the river “intact for the next 5,000 years,” and started arguing that the soft-bottom segments were actually a riparian habitat that had been hiding in plain sight. The MRCA (Mountains Recreation & Conservation Authority) started acquiring small parcels along the Glendale Narrows in the early 2000s and called the strategy the string of pearls. Each pearl is a half-acre to four-acre park giving public access to the channel.
In 2022 LA County approved the multi-billion-dollar LA River Master Plan led by OLIN and Frank Gehry’s office. The work will run for decades. Most of what’s on the ground today is the pearl-strand the MRCA built in the meantime.
The trail: LA River West Bank Trail
The main spine is the LA River West Bank Trail, a 14.4-mile out-and-back that follows the soft-bottom channel from south of Griffith Park up to Burbank. It is paved or partially paved the whole way, flat, dog-friendly on leash, and used by walkers, runners, road bikers and a steady stream of food-delivery cyclists. AllTrails rates it Easy. The actual experience varies a lot section by section.
The best two-mile stretch sits between the Sunnynook Pedestrian Bridge in Atwater Village and the Hyperion Bridge to the south. Willows, cattails, herons, the occasional cormorant. The freeway is overhead. The traffic is loud and the birds do not care.
If you want one short loop that captures the Glendale Narrows experience, park at Marsh Park, walk south to the Great Heron Gates at Fletcher Drive, cross the bridge, walk back on the east bank, and finish at Marsh. About 3.5 miles, an hour and a half at strolling pace.
The pocket parks, from south to north
The string of pearls runs roughly south to north along the western bank, in the Frogtown / Elysian Valley neighborhood. Each park is small. The point is access, not amenity.
River Garden Park sits on the grounds of the LA River Center & Gardens, the old Lawry’s California Center compound that is now MRCA headquarters. It is the southernmost public landscape directly associated with the corridor and a good place to start if you want context before the walk.
Elysian Valley Gateway Park on Knox Avenue marks the southern entrance to the string of pearls. Picnic tables, native plantings, ADA-accessible access to the L.A. River bikeway.
Egret Park at Riverside Drive and Barclay Street is a half-acre native-planting parcel with a small river-watching corner.
Oso Park at Oros Street and Riverside Drive is a few picnic tables and a strip of bank access. Quiet.
Steelhead Park at the end of Oros Street is named for the steelhead trout that used to migrate up the LA River from the Pacific until the concrete went in. Native plantings, a small event space, river views. The name carries the obvious weight.
Great Heron Gates at Rattlesnake Park at Fletcher Drive is the marker piece. Sculptor Brett Goldstone built the steel heron gates that frame the river entrance. This is the photo most people have seen of the Glendale Narrows even if they don’t know it.
Marsh Park is the four-acre flagship. Built on a former rail spur, it has a stage area, picnic terraces, a kayak launch in season, and the kind of mature shade trees the rest of the string of pearls is still growing into. If you have visitors and want to give them the Glendale Narrows in 45 minutes, you park here.
Further north and on the tributaries
Two more sites are not directly on the West Bank Trail but belong on this map.
Richard Lillard Outdoor Classroom in Studio City is a native-habitat education plot on the river, used by local schools. It is small, fenced and not really a walking destination. It is one of the older pieces of the public-access strategy.
Tujunga Wash Greenway is the major tributary park. The 4.5-mile path runs along the wash in Van Nuys past Judy Baca’s mile-long mural The Great Wall of Los Angeles. Different watershed, same general philosophy of reclaiming a flood-control channel as a walkable corridor.
How to get there and what to expect
The best parking and entry points along the West Bank Trail are Marsh Park (on Rosanna Street), the Fletcher Drive lot near the Great Heron Gates, the Sunnynook Pedestrian Bridge in Atwater Village, and the Los Feliz Boulevard bridge at the south end of Griffith Park.
The trail is unshaded in long stretches. In summer go before 9 a.m. or after 6 p.m. In winter go any time. After rain the channel runs fast and the soft-bottom sections look like a small wild river, which is the whole point.
For birds: the section between Sunnynook and the Hyperion Bridge is the most reliable. Year-round residents include great blue herons, snowy egrets, black-necked stilts, killdeer, mallards and the occasional belted kingfisher. Winter brings white-faced ibis and northern shovelers. Bring binoculars.
The neighborhood around Frogtown has changed fast in the last ten years. Coffee shops, breweries, design studios. Some long-time residents will tell you about it bluntly if you ask. The displacement story is part of walking the river now, and worth noticing.
The southern extension and the long view
The Glendale Narrows is the headline, but the soft-bottom philosophy carries downstream. The MRCA recently built Compton Creek Natural Park on the grounds of George Washington Elementary in Compton, reconnecting a long-isolated neighborhood to its tributary. Further upstream on the main river, the Sepulveda Basin Recreation Area is the second of the three soft-bottom segments and holds the Sepulveda Basin Wildlife Reserve. None of these sites are obvious neighbors to the Glendale Narrows on a map, but they share the strategy and the master plan envelope.
The full LA River Master Plan runs for decades. What is on the ground today is the pearl strand the MRCA built in the gap between 1985 and the master plan starting to deliver at scale. More than most people expect. A working pilot, not the finished thing.
If you only do one thing
Park at Marsh Park around 5 p.m. in October. Walk south on the bike path. Stop at the Great Heron Gates and look down. There will be herons, almost certainly. The freeway will be loud. The light will turn the willows gold. Walk back.
