This short hike travels up a narrow history-filled canyon to a charming double waterfall. At the turn of the previous century, the canyon was home to Rubio Pavilion, at the base of the Mount Lowe Incline Tramway, which escorted visitors to an immensely popular resort atop the ridge to the west. A hundred years later, only the foundation remains and nature has rebounded to provide a rustic hiking alley. It is 1.3 miles round trip with 350 feet of elevation gain to reach a duo of stacked cascades within a narrow section of the canyon.
- Rubio Canyon is one of the Los Angeles waterfall hikes.
Beginning from the trailhead along Rubio Vista Road in Altadena, hike north up the west side of the canyon. Because this trail starts outside Angeles National Forest, an Adventure Pass is not required.
The single track traces the west side of the canyon along the route of the long-removed trolly line into the canyon. The unmaintained trail is in great shape, offering brisk hiking over the first half mile to the Rubio Pavilion site. The pavilion was operational from 1893 to 1936 as the starting station for the steep tram ride up to Mount Lowe. The pavilion was crushed by a storm-driven boulder, but sections of the foundation are still visible from the trail.
Just past the foundation, the trail turns left, climbing out of the canyon and up the ridge to Mount Lowe along the path of the old tram line. When this happens, continue straight up the creek on a rapidly diminishing trail.
A tenth of a mile of off-trail rock hopping brings you up the creek to a double waterfall. The bottom half is named Ribbon Rock Falls and the top is Moss Grotto Falls. The pair is well suited for each other.
When you are finished, hike south back to the trailhead or consider a few extensions. From the base of Ribbon Rock Falls, a narrow track continues to the east farther up Rubio Canyon toward Grand Chasm Falls. This trail is covered well on Dan’s Hiking Page. Another way to explore more of this area is to venture up Incline Trail on the west side of the canyon. This steep track following the old tram route up to Echo Mountain, climbing 1,100 feet over approximately 1.5 miles. Given the pitch of the trail, it is a better descent route. Hike up Sam Merrill Trail to Echo Mountain, then hike down Incline Trail to Rubio Canyon. From the bottom of Rubio Canyon Trail, continue down Rubio Canyon Drive and across a section of Altadena Crest Trail to return to the Echo Mountain trailhead for a six-mile hike. This loop is shown in the map below.
The short hike to Moss Grotto Falls and Ribbon Rock Falls is a pleasant excursion in rustic Rubio Canyon. Dogs are permitted, but the trail is not suitable for mountain bikes. No fee or permit is required, so get out and enjoy.
To get to the trailhead: From the 210 Freeway in Pasadena, take exit 26 and head north on Lake Ave. Drive three miles to Dolores Drive and turn right. Make the fourth right (after 0.4 miles) on Rubio Canyon Road. After 1/4 mile, turn left to stay on Rubio Canyon Road, and then make a quick right on Rubio Vista Drive. Less than a quarter mile up, find the trailhead on the right side of the road between houses numbered 1351 and 1342.
