Are you interested in hiking to Eaton Canyon Falls, but need a guide to make the best of your visit? You’ve come to the right place.
Eaton Canyon Falls is the most popular waterfall in the San Gabriel Mountains. The 4 mile hike requires crossing the creek multiple times as you weave your way through the canyon floor before reaching the beautiful 40 ft falls. Parking lot and restrooms can be found at the trailhead. Dogs must be on a leash.
In This Guide You Will:
- Choose from 3 trailheads
- Know what gear to take
- Learn how to catch a roaring waterfall in the offseason
- Know the best time of the day and week to visit
- Weather conditions
Eaton Canyon Trail Map
This hike has 3 trailheads.
Trailhead 1: The first and more popular trailhead extends the hike to 4.4 miles, and begins at the parking lot where the Nature Center is located.
You can get directions by clicking the link: 1750 N Altadena Dr, Pasadena, CA 91107.
Trailhead 2: The second trailhead begins further up the canyon off of Pinecrest Dr where the Mount Wilson/Pinecrest Gate is located. Click here to get directons.
Keep in mind the hours for the Mt Wilson Toll Rd are 8am – 7:30pm Monday through Sunday.
This trailhead skips the Eaton Wash at the mouth of the canyon, and takes you across the Chuck Ballard Memorial Bridge via the Mount Wilson Toll Rd then down onto the canyon floor where the trail continues underneath the bridge.
This hike totals 1.9 miles with a 606 ft elevation gain.
Trailhead 3: The third and least known route is the Henninger Trailhead off of N Altadena, which cuts halfway through the Eaton Wash. Keep in mind that crossing the wash may be a difficult feat during very rainy seasons.
You can get to the trailhead by clicking here. The hike from the Henninger Trailhead is about 3.3 miles.
I highly suggest starting on the 1st trailhead, which is closest to the Nature Center and allows you to experience the full beauty of Eaton Canyon.

No fee or permit is currently required to visit or park. You can double check here as conditions may change. ecnca.org/
Best Days of The Week to Visit: If you can make a trip to Eaton Canyon Mon- Thur please do so. Trust me, you will avoid the majority of the crowds.
Best Time of The Day to Visit: If you’re visiting Mon-Thurs the time doesn’t really matter, but obviously the earlier the better or anytime after 2pm. If you’re going on a weekend be at the trailhead at 7am the latest, otherwise expect A LOT of people.
Recommended Gear: Unless you have exceptional balance, take poles to help you with the creek crossings. A good pair of hiking shoes or boots with traction will also make your visit more enjoyable. I use Trailbuddy Poles and Merrel boots.
Best Season to Visit: Definitely Spring as this is when the falls will have more water. If you want to catch a roaring waterfall in the off-seasons, pay a visit the day it rains or the following day, which is what we did for this post. We visited on 12/29/21. It rained the previous day.
Eaton Canyon History
The image above is a vintage photograph I purchased depicting Eaton Canyon Falls at the beginning of the 20th century. Notice the rock which is currently lodged at the top of the falls is missing.
Eaton Canyon has a long and rich history beginning with the Tongva people, the Spanish, Mexicans, and last but not least the Americans.
Much of the Tongva history has been lost, but we do know the Spanish called Eaton Canyon, Canon Precipicio, which means the “Precipice Canyon” due its steep canyon walls.
In 1877 legendary conservationist (and hero in my book), John Muir, shown below, visited Eaton Canyon Falls and dubbed it the Yosemite of the San Gabriels. What an honor!
Eaton Canyon had multiple uses including hunting, water for irrigation, and even gold prospecting.
Once CA became US territory, a man by the name of Judge Benjamin Eaton, for which the canyon is now named after, purchased Fair Oaks Ranch and the surrounding land in 1865.
The street cutting through Old Town Pasadena, Fair Oaks Ave, bears the name of this long forgotten ranch.
Judge Eaton, a patriarch of the San Gabriel Valley, was a pioneer in tapping water from the creek and used it to irrigate his ranch.
He built a water system consisting of miles of pipeline running through the canyon, which is still there!
Here’s a picture of one of those 157 year old pipes. Give or take a few years.
Many of the surrounding canyons in the San Gabriels contain these pipes, as they were also used for irrigation.
Water tunnels were constructed for irrigation purposes, with the longest measuring 600-700 ft according to the author of secretmines.com.
Unfortunately, this tunnel was blasted in the 1980’s to block the entrance, but part of the rock wall still remains.
You can see the entrance of a different tunnel on your way to the falls.
It was one of these types of tunnels which allowed you to bypass the fatal Razorback Ridge, and safely access the second hidden waterfall in the Canyon.
Although hard rock mining never took place in Eaton Canyon, placer mining (panning for gold in the creek) wasn’t rare.
In 1853-1854, gold was found in Santa Anita Ranch (owned by Lucky Balwdin who now has a Belgian pub with my favorite beer named after him) and in the surrounding canyons including Eaton, Rubio, and Arroyo Seco.
Deep sand pits at the Eaton Wash which were used to look for gold still remain to this day.
Over the span of 18 years, a total of 2 million dollars worth of gold dust was sold from San Gabriel, Santa Anita, and Eaton Canyon.
