Eaton Canyon Falls: Trail Overview

Eaton Canyon Falls is the most visited waterfall hike in the San Gabriel Mountains, and for good reason. The trail starts at the Eaton Canyon Nature Center in Pasadena, follows a wide, mostly flat wash, crosses Eaton Creek several times, and ends at a stunning 40-foot waterfall tucked into a narrow canyon. On any given weekend before the fire, you would see hundreds of hikers, families, trail runners, and dog walkers along this path.

The hike itself is straightforward and suitable for a wide range of fitness levels. It has long been a go-to recommendation for visitors new to hiking in the San Gabriel Valley. When the trail eventually reopens, it will almost certainly be one of the first hikes to draw crowds again.

Getting There and Parking

The trailhead is located at the Eaton Canyon Nature Center, one of the most accessible entry points to the San Gabriel Mountains from the Pasadena and Altadena area.

Parking at the Nature Center lot is free, according to LA County Parks and Recreation. However, the lot is notoriously crowded. On weekends, it can fill before 8 AM during peak season. If the main lot is full, overflow parking is available in the Equestrian Area nearby.

What the Trail Is Like

The Eaton Canyon Falls trail begins with a wide, flat fire road that runs alongside Eaton Creek. After about a mile, you will reach a junction where you turn right and enter the narrower canyon trail. This section involves multiple stream crossings where you will need to hop across rocks or wade through shallow water depending on the season.

The final stretch narrows considerably as the canyon walls close in. You will hear the waterfall before you see it. The trail ends at the base of the falls, where Eaton Creek drops roughly 40 feet over a vertical rock face into a shallow pool. The mist from the falls is a welcome reward, especially on warmer days.

The trail is not paved and does include loose rock, sand, and uneven terrain. It is manageable for most hikers, including children and older adults, with the right footwear. Flip-flops and sandals are a common mistake; sturdy closed-toe shoes with grip are essential.

Best Time to Visit

The best time to see Eaton Canyon Falls at full force is during spring (March through May), after winter rains and snowmelt from the San Gabriel Mountains have fed the creek. During this window, the 40-foot cascade runs heavy and the canyon is green and lush.

The waterfall technically flows year-round, but by late summer and into fall, it often slows to a trickle. Winter visits are also excellent when rain has been recent, though stream crossings can be deeper and trickier during active storm seasons.

Safety Tips

Eaton Canyon is generally a safe hike, but the terrain and wildlife demand respect. Here is what to watch for:

• Rattlesnakes: Southern Pacific rattlesnakes are active in warmer months, especially on warm rocks alongside the trail. Stay on the path, watch where you step and place your hands, and give any snake at least 4 to 6 feet of space.
• Heat: Parts of the trail offer minimal shade. On summer days when temperatures in Pasadena can exceed 95 degrees, start early and bring at least 1 liter of water per person. A hat and sunscreen are not optional.
• Stream crossings: After rain, water levels rise quickly. Do not attempt to cross water above knee height. Hiking poles help with balance on slippery rocks.
• Waterfall safety: Never swim or wade upstream near the falls. Currents near the base can pull swimmers into dangerous areas. Stay on dry ground and do not climb the rock face.
• Sun protection: Wear lightweight, breathable clothing, apply sunscreen, and bring sunglasses. Even on overcast days, UV exposure at elevation is stronger than you expect.
• Cell service: Coverage is limited deeper in the canyon. Let someone know your hiking plans and expected return time before you head out.

Dogs and Kids on the Trail

Dogs are welcome on the Eaton Canyon trail and must remain on a leash at all times. Bring water and a collapsible bowl for your dog, especially on warm days. Note that dogs are not permitted on guided nature walks offered through the Nature Center, with the exception of service animals.

Kids do well on this trail. It is one of the most family-friendly waterfall hikes in all of Los Angeles County. The stream crossings add an element of adventure for younger hikers, and the waterfall payoff at the end keeps them motivated. Children must be accompanied by a responsible adult. Sturdy shoes (not sandals) are particularly important for kids on the rocky sections.

The Eaton Fire and What It Means for the Trail

In January 2025, the Eaton Fire swept through the canyon, burning through thousands of acres and stripping away the vegetation that had stabilized the canyon slopes and hillsides for decades. The fire left the soil exposed and hydrophobic, meaning rainwater runs off rather than soaking in.

Just weeks later, a series of atmospheric river storms pounded the burn scar, triggering powerful debris flows and landslides that dramatically altered the terrain. What were once well-used trails and scenic overlooks became highly unstable and dangerous zones.

The U.S. Forest Service issued a closure order effective through December 31, 2027, covering all trails within the fire perimeter. The closure applies to Angeles National Forest land, City of Pasadena Open Space, and the LA County Natural Area. Trail designers, biologists, and ecologists will need to reassess the entire trail network from the ground up before any reopening can happen.

This is not a short-term inconvenience. The canyon needs time to heal, and premature human traffic could cause further erosion. Respect the closure.

Three Alternative Hikes While Eaton Canyon Is Closed

If you had plans to hike Eaton Canyon, these three nearby trails offer similar experiences and are currently open.

Monrovia Canyon Falls

This is the closest alternative if you want an easy waterfall hike. Monrovia Canyon Park reopened in June 2025, and the Falls Trail is a gentle 1.6-mile round trip with 350 feet of elevation gain. The waterfall runs year-round thanks to an artesian spring. The park is closed on Tuesdays, and there is a $5 vehicle entry fee on weekends.

Mt. Wilson Trail from Sierra Madre

For a more challenging adventure, the Mt. Wilson Trail reopened in January 2026 after post-fire repairs. Starting in downtown Sierra Madre, this is a proper mountain hike with significant elevation gain. You do not need to summit to enjoy it. The first 2 miles offer great views with moderate effort. Community volunteers maintain this trail, so conditions may vary after storms. Call the Sierra Madre Police Department at (626) 355-1414 for current conditions before you go.

Switzer Falls via Gabrielino Trail

Located off the Angeles Crest Highway in the Angeles National Forest, Switzer Falls is a 3.6-mile round trip with 685 feet of elevation gain. The trail follows the Arroyo Seco through a beautiful canyon lined with oaks and alder. The falls are about 50 feet high. An Adventure Pass ($5/day or $30/year) is required to park. Get there early; the parking lot fills quickly on weekends.

Where to Eat After Your Hike

Whether you hike one of the alternatives or bookmark this section for when Eaton Canyon reopens, the Pasadena and Altadena area has excellent post-hike dining within minutes of the trailhead.

• Side Pie (Altadena) - Corner of Altadena Drive and Lake Avenue. Great pizza after a long trail day.
• Mint Leaf I (2535 E Washington Blvd, Pasadena) - Indian cuisine less than a mile from the Nature Center.
• Lavender & Honey (Altadena) - A local favorite for brunch and lighter post-hike meals.
• El Patron (Altadena) - Hearty Mexican favorites including fajitas and wet burritos.
• North Tacos (Altadena) - Quick, affordable tacos and burritos perfect for refueling.
