Take a stroll through the foothills of the Angeles Forest and into a woodsy canyon where you’ll be rewarded with a beautiful cascade.

Etiwanda Falls is a very popular 15-20 ft cascade located in North Etiwanda Preserve, an area known for its rich history. The moderately difficult hike primarily consists of a shadeless dirt road. However, once inside the canyon, the scenery transforms into a luscious mountain paradise.

After you’ve payed the parking fee, head straight through the next gate towards the mountains.

Although not on the map, the pavilion below is easy to spot and features a lot of interesting information regarding the area including its history, endangered species, and plants.

I highly recommend it, as it’s only a 1 minute detour.

The entirety of the trail is a not so exciting dirt road, but luckily you’ll have a great view of the valley to the south, Cucamonga and Etiwanda Peak towering above you to the north, and Old Greyback (San Gorgonio) to the east.

Mount San Gorgonio is the snowy peak in the image below.

Further up the road you’ll come across a late 19th century water pipe that once allowed ranchers and farmers to harness the waters of East Etiwanda Creek.

The structure shown below, which is known as an overflow drain, was used along with the water pipes.

Hopefully, it’ll be flowing during your visit as it was on mine.

At the top of the falls, you’ll have a stunning view of the East Etiwanda Canyon mouth opening up, and the creek gushing over the second much smaller falls.

Deeper into the canyon, White Alder trees decorate the landscape, making it look like a wooden scenery you normally see in movies.

There it is, beautiful Etiwanda Falls. You would never think to see something like this in Rancho Cucamonga.

The second much smaller falls is located below Etiwanda Falls, and directs the creek into a pool.

However, I don’t recommend trying to climb down, as it’s steep and dangerous.

I was shocked to see this much water flowing in December, especially after a very dry season, but that is probably why Etiwanda Falls has become so popular.

Etiwanda Falls History

Although American settlers named Etiwanda Falls in 1882 after a native tribe from Lake Michigan, the area belonged to two California tribes:

The first tribe were the Tongva people, or Gabrielinos (after the mission of San Gabriel in LA), as they were called by the Spanish.

The second tribe were the Taaqtam people, also known as Serranos by the Spanish, which means “people of the pines” because they were the more mountaineer type out of all the local tribes.

As is the case with most of our California tribes, the history has been unfortunately, lost.

Hence, what we know traces back to 1774, to the days when Spanish Captain Juan Bautista de Anza passed through the area with the intention of finding an overland trail from Mexico to the San Gabriel Mission.

The first Europeans to settle in the area were the Spanish, who primarily used the land for ranching. Little changed when Mexico won its independence and took over the land.

However, when the US took hold of the fertile land, it was quickly converted into groves, which is why you still see a few fruit groves scattered throughout Riverside and San Bernardino.


The canyons in North Etiwanda Preserve were one of the first in the area to be used for harvesting and transporting water, first via simple ditches and canals dug in the ground, then using wooden flumes.

When the wooden flumes were destroyed by floods or decayed, they were replaced with clay pipes, which minimized the loss of water caused by evaporation, absorption, or spilling outside of the flumes. You can still see remnants of the clay scattered throughout the trail.

Stone walls, whose remnant’s can also be seen today, were built to protect the clay pipes and maintain the proper gradient, thus ensuring gravity flow.

Keep an eye out for cylinder shaped concrete structures. These chambers housed multiple pipe openings, and were used to cut water off from certain pipes while directing the flow to others in order to facilitate the sharing of water between landowners.

The Zanjero, a Spanish word for “ditch master” was responsible for controlling and directing the water to landowners at their appropriate times.

Eventually, clay pipes were replaced by concrete pipes buried underground.
