Overview
Eaton Canyon Falls is the closest substantial waterfall to central Los Angeles, and the ease of access makes it one of the most popular hikes in the entire LA metro area. The 3.4-mile out-and-back from the Eaton Canyon Natural Area Park leads to a 40-foot waterfall tucked into a rocky grotto at the mouth of Eaton Canyon. The elevation gain is minimal, and the trail follows a mostly flat wash for most of its length.
This is not a wilderness experience. On a weekend after rain, you'll share the trail with hundreds of other hikers. But the waterfall is genuinely impressive when it's flowing, and the fact that you can walk from a Pasadena parking lot to a 40-foot cascade in under an hour is remarkable.
The waterfall flows best from December through April after winter rains. By late summer, it may be reduced to a trickle or dry completely.
The Route
Miles 0 to 0.5: Nature center to the wash. From the parking lot, walk through the Eaton Canyon Natural Area and cross the bridge into the main wash. The nature center has restrooms and interpretive displays if you want to stop.
Miles 0.5 to 1.2: Wash walk. The trail follows the rocky wash upstream. The surface is uneven river rock and sand. This section is flat and wide. In dry conditions, the wash may have little to no water. After rain, expect some shallow water and muddy sections.
Miles 1.2 to 1.7: Creek crossing and falls approach. The trail enters the narrower canyon section and crosses the creek several times on rocks. The crossings are easy in low water but can be tricky after rain. The canyon walls close in, and the trail becomes rougher with more rock scrambling. The waterfall appears at the end of the canyon, dropping 40 feet into a shallow pool.
When to Visit
December through April: The best window. Winter rains feed the waterfall and create the most impressive flow. January through March after a good storm season is when the falls are at their most photogenic.
May through November: The falls diminish significantly. By late summer, the waterfall may be dry or barely flowing. The hike is still pleasant for the canyon scenery, but the payoff is much less dramatic.
After a rainstorm: The best time to visit. Wait 1 to 2 days after a significant rain for the creek to be flowing but the trail to be manageable. Going during a storm is dangerous due to flash flood risk in the canyon.
What to Bring
- Sturdy shoes: The wash is rocky and uneven. The creek crossings near the falls require shoes that can handle wet rock. Avoid sandals.
- Water: 1 liter per person is sufficient. The hike is short.
- Sun protection: The wash is exposed with limited shade.
- Camera: The waterfall is photogenic, especially after rain when the water volume is high.
Practical Details
Parking: Eaton Canyon Natural Area Park has a large free parking lot with about 100 spaces, restrooms, and a nature center. The park opens at sunrise and closes at sunset. On weekends after rain (when the waterfall is flowing well), the lot fills by 10 AM. Arrive early or come on a weekday.
No dogs: Dogs are not allowed on the trail within Eaton Canyon Natural Area.
No fee: The park and trail are free. No Adventure Pass or other pass is required.
Flash flood danger: Eaton Canyon is a narrow wash that funnels water quickly during rain. Do not hike to the falls during rain or when rain is forecast. If you hear rushing water or see the water level rising, leave the wash immediately and get to high ground.
Crowds: This is one of the busiest trails in the LA area. After a good rainstorm, thousands of people may visit in a single weekend. If crowds bother you, go on a weekday morning.
Difficulty context: The main wash section is easy. The creek crossings and rock scrambling near the falls bump the difficulty to easy-moderate. Most reasonably fit people, including older children, can complete this hike.
Getting There
From downtown Pasadena, take N. Altadena Drive north about 1.5 miles to the Eaton Canyon Natural Area Park at 1750 N. Altadena Drive. The parking lot is on the right. Total drive time from central Pasadena is about 10 minutes. From downtown Los Angeles, take the 210 Freeway to the Altadena Drive exit and head north. About 25 minutes.
Beyond Eaton Canyon Falls
For a more challenging extension, some hikers scramble above the falls to reach a second, smaller waterfall in the upper canyon. This scramble is steep, exposed, and involves climbing on loose rock above a drop. Multiple rescues and injuries occur here every year. It is not recommended unless you have scrambling experience and are comfortable with significant exposure.
For other nearby waterfall hikes, Millard Falls (1 mile round trip) in the Millard Canyon area of Angeles National Forest offers a smaller but quieter waterfall experience. Switzer Falls (4.5 miles round trip) is another popular option deeper in the forest.
Eaton Canyon Falls is the hike that proves you don't need to leave the city for a decent waterfall. It's short, free, and remarkably scenic after a good rain. The trade-off is crowds, but that's the price of accessibility. Come after a storm, come early, and bring shoes that can handle wet rocks.
When you're ready for a longer outing in Angeles National Forest, the options multiply quickly. Sturtevant Falls in Big Santa Anita Canyon above Arcadia offers a more secluded 50-foot waterfall with the added interest of historic backcountry cabins along the route. Trail Canyon Falls near Sunland-Tujunga draws far fewer visitors than Eaton Canyon for a similar payoff. For summit views instead of waterfalls, Josephine Peak is the least-crowded moderate summit in the western front range, and San Gabriel Peak delivers one of the best panoramas in Southern California from 6,161 feet.
