It used to be that you could walk across the Colorado Street Bridge—Pasadena’s most famous—and enjoy a glorious view over the Arroyo Seco and its surroundings. But in recent years, a tall chain-link fence has gone up along the walkways (possibly to hinder suicide attempts) which obstructs the view and makes walking across the bridge now feel more like stepping through a chicken coop.
Oh well. The bridge is far more pretty from below anyway.
The Arroyo Seco cuts a steep canyon through the west side of Pasadena, separating it from the hilly neighborhoods of Northeast Los Angeles. As Pasadena grew, this canyon posed a daunting obstacle to accessing the neighborhoods to the west, one that would be bridged over many times to link both sides of the canyon. Although the stream of the Arroyo Seco itself is confined to a narrow concrete channel for most of its length through Pasadena, the adjoining landscape is far more natural than that along the Los Angeles River. Beneath the many bridges that span the canyon, the wooded canyon offers a lovely secluded bit of nature close to Old Pasadena.
Lower Arroyo Park encompasses the entirety of the canyon between the Holly Street Bridge (just north of the 134 Freeway Bridge) and the southern city limits of Pasadena. It’s also surprisingly transit-accessible. The closest transit stop is the bus stop in front of the Norton Simon Museum at Colorado St/Orange Grove Blvd, which is served by the Metro #180/181/780 routes between Pasadena and Hollywood. The Gold Line stops at the Memorial Park and Del Mar stations near Old Pasadena just to the east, a short bus ride or about a 20 minute walk away.
At first glance, it’s not at all clear how to get from Colorado Boulevard down to the Arroyo Seco. But it’s an easy—if slightly roundabout—walk to reach the canyon. Don’t walk towards the bridge. Instead, walk north on Orange Grove across the freeway and make the first left onto Holly Street. Walk downhill and make the next left, which will take you onto Arroyo Drive and underneath the 134 freeway. As you pass under the freeway, the span of the majestic Colorado Street Bridge reveals itself to you, arcing gracefully across the canyon. Sitting in the shadow of the bridge is a lavish condo building, with tile work depicting the arches of the bridge that are visible just beyond.
At the bottom of the street, where Arroyo Drive meets Arroyo Blvd, you’ll come across a wonderful new park spread out beneath the Colorado Street Bridge. This is Desiderio Neighborhood Park, completed only a year ago and sitting on a small plateau between Pasadena and the canyon proper. And it really is a beautiful park, blending together the natural habitat below with the urban landscape above. Winding pathways take you through a naturalistic area made to mimic the arroyo habitat, with a dry creek bed filled with colorful wildflowers. Amidst the bright orange poppies adorning the park are many picnic tables, making this a delightful place to enjoy a meal. Intricate street lamps dot the park, bathing it in a warm yellow glow in the evening. A brand new playground and restrooms stand in the back corner. And it all sits under the stately aura of the Colorado Street Bridge, casting long arching shadows over the park while the bell tower of the Richard H. Chambers U.S. Court of Appeals building (originally built in the 1920s as a lavish hotel) looms over the hillside.
Continue to the other end of the park, to the intersection of Arroyo Blvd and Westminster Drive, and cross Arroyo. From here, there are multiple ways downhill to the Arroyo Seco. The quickest one is a shady trail directly next to this intersection, lined with rustic stone walls built in the Park Style common of New Deal conservation projects. Or you can walk south down Arroyo Blvd for a block to La Casita del Arroyo, a meeting hall that dates back to the 1930s and run by the Pasadena Garden Club, which cultivates a small but beautiful set of gardens surrounding the meeting hall. From the south side of the building, a few trails lead downhill to the Arroyo Seco.
Lower Arroyo Park is a minimally developed park, set aside early in Pasadena’s history to preserve the canyon from development. None of the trails are marked with signs, nor are there any trail maps, but finding your way around is simple enough. There are really only three directions you can go: uphill, downhill, or along the bottom. Lizards constantly dart across the dirt trails of the canyon, and rabbits, squirrels, and chipmunks are also common.
As you walk through the park, you’ll find the aging remnants of old park infrastructure: a crumbling stone wall here, an old bench there. The cliff face on the west side of the canyon holds numerous staircases that seem to vanish into the overgrowth, while castle-like mansions poke out on the ridge above, aloof and disconnected from the nature beneath them. Some trails feel more like worn foot paths as the dry vegetation encroaches on them. In contrast to Pasadena’s typically heavily-cultivated parks, such as the lush lawns surrounding the Rose Bowl just to the north, Lower Arroyo Park feels mostly forgotten by the city above. Aside from the regular joggers and hikers (and the occasional equestrian trotting up from a stable in South Pasadena) you’ll encounter along the Arroyo Seco channel, the trails are very quiet.
Ironically, the Lower Arroyo was once home to a major tourist attraction. In the 1900s, Adolphus Busch (of the Anheuser-Busch brewing company) turned his summer home at the southern end of the park into an elaborate garden filled with statues, picturesque buildings, and waterfalls. This was the original “Busch Gardens,” long before it turned into a chain of amusement parks, and it stayed opened until the 1930s before it was closed and replaced with a residential neighborhood, with few traces of the gardens remaining.
After you make it down to the bottom of the canyon, head south on any of the trails and you’ll soon come across the small parking area for Lower Arroyo Park. Here is one of the few pedestrian bridges over the Arroyo Seco channel, some restrooms, a water fountain, and two rather unique recreational areas. Behind the restrooms is a large casting pond, essentially just a bare, rectangular concrete pool. A few pool rings float on the water, presumably to act as targets for people to practice their casting skills (at least I presume that’s what they’re for… I’ve never fished). A local casting club uses the pond for classes, although a more common use I’ve seen for the pond is dogwalkers letting their pets take a bath and playing fetch in the water.
Across the Arroyo Seco channel from the parking lot is an archery range, and you do regularly see archers honing their skills here. Stacks of straw bale sit against the hillside, sometimes with targets mounted on them, while triangular posts serve as racks to mount your bows. The largest range, with a good half-dozen bales, sits just south of the little pedestrian bridge (and it’s fun to watch if you’re lucky enough to catch a group of friends doing a tournament here) but you’ll find plenty of individual bales scattered along the base of the hillside, where archers hone their craft.
But it’s the views from beneath the Colorado Street Bridge that are the best feature of this park, so let’s head there. Feel free to take any of the trails north, it doesn’t really matter whether you follow the Arroyo Seco channel (the most straightforward path) or one of the trails through the woods (which provide more shade). Along the west bank, some water from the stream has been diverted through the woods to create a riparian habitat. Just shy of the Colorado Street Bridge is a little footbridge that connects the trails along both sides of the Arroyo Seco channel, which is crucial because the trail on the east bank (the Pasadena side) is the only one that continues up the canyon past the bridge.
As you approach the Colorado Street Bridge, the canyon narrows and the vegetation grows thicker. From below, you can admire the intricate details of the bridge and the massive arches swooping high above your head. A grove of eucalyptus trees sits beneath the bridge, filling the air with their fragrant scent. Unlike the constant rumble of traffic over the nearby freeway bridge, the traffic on the slender Colorado Street Bridge seems so far away as to be almost inaudible.
Directly beneath the bridge is an interesting feature totally hidden from above. The concrete channel of the Arroyo Seco comes to an abrupt halt at a tall spillway that marks a dam below the bridge. Also hidden from above but clearly visible from the path is a lower level bridge attached to the bottom of the Colorado Street Bridge, dwarfed by the larger structure. This is the Parker-Mayberry Bridge, built in the 1910s to replace an earlier bridge that had washed out in a flood and constructed to mimic the style of the larger bridge above it. Originally it was built to provide access to orchards on the west bank of the Arroyo, but today it’s closed to vehicles and most approaches to it are fenced off. However, you can get onto it from the path with just a little bit of work. Just go up the trail under the bridge and look for the short, crumbling stone staircase to your right just past the bridge. This will take you up to a patch of ground next to the bridge. An easy hop over a short wall and you’ll be on the bridge, where you can admire the massive structure towering over you and the dam beneath you.
From here, you can either retrace your path back uphill to Desiderio Neighborhood Park and back to the bus stop, or continue north up the path and enjoy one of the few natural stretches of the Arroyo Seco. Behind the dam, the stream trickles through a lush landscape beneath the bridges. Water fowl can often be seen wading in the shallow stream, while squirrels and lizards dart through the trees and bushes. Here, beneath the roar of the freeway traffic, a shady oasis sits.
Speaking of the freeway, you’ll be passing under that next. Although the 134 freeway bridge lacks the grace of the Colorado Street Bridge, it still impresses by its sheer size. Beneath the freeway is a dirt clearing next to the trail that offers unobstructed access to the Arroyo Seco stream, which burbles over a set of boulders. Here you can enjoy wading in the stream, skip stones across the water, or just enjoy the shade under the dull rumble of the traffic passing overhead.
Carry along the trail and you’ll rejoin Arroyo Blvd. Unfortunately, this stretch of Arroyo Blvd lacks sidewalks, making returning to Desiderio Park along the street from here a dicey prospect. Instead, continue on the path heading north towards the Rose Bowl, which will become visible in the distance as you round the bend. The next bridge you’ll pass under will be the Holly Street Bridge, and when you reach the first lawn on your right, next to the aquatics center, cross the street and look for a trail that will take you back up the hillside to the Holly Street Bridge (you’ll actually be able to see traces of it from Arroyo Blvd—just look for the little stone walls up on the hill after you pass under Holly Street). Once you reach Holly Street, you just have to walk back uphill to Orange Grove Blvd to return to the start.
