Recently, I played a game on a hiking group on Facebook called “Can you name this spot?”. I would show a picture and elicit other hikers to identify the location. When I posted a photograph of Carson’s Crossing in Los Peñasquitos Canyon, one of the hikers stated “The Florida Everglades.” How on Earth does one confuse semi-arid San Diego County with the marshes and swamps of southern Florida? Visit Peñasquitos Canyon, and the answer will be less mysterious than you’d think.

Grassy meadow on the foot trail

The canyon and attending preserve encompasses a six mile strip of land bordered by suburban development. The preserve protects the ecosystem within, which is dominated by the year-round flow of Peñasquitos Creek. This surprisingly robust creek supports a dense strip of riparian wilderness unrivaled anywhere else in San Diego County. In fact, parts of this strip of woodland are so dense, damp, and lush, that it is easy to forget that with a few hundred yards on either side of the creek emerges the usual scratchy carpet of chaparral. Peñasquitos Creek is a lesson in the power of water and its ability to turn a near desert into a subtropical paradise.

Near Carsons Crossing

This write-up describes the eastern (and more lush) portion of the canyon, which divides at a waterfall about halfway through the preserve. This route also eschews the crowded fire road running parallel to the creek on the south, as well as the trail running parallel to the north. This single-track trail runs near the banks of the creek and through the densest parts of the woods. In theory, this should also allow you a respite from the multitude of mountain bikers who frequent the main trail, although you should still be prepared to encounter a few bikers who disregard the clearly marked signs describing this trail as off-limits to all but bipeds and quadrupeds.

Trail near dusk

After parking at the lot and paying the fee ($3 at the time of writing), find the trailhead marked by an info kiosk and a closed gate. A gap allows you to emerge onto the wide fire road that heads due west. After about a tenth of a mile, a smaller single-track will emerge on the right. Take it. You’ll soon pass through dense patches of prickly pear cactus into a lush woodland of coast live oak, sycamore, and willow trees. This scenery will stay with you through the majority of the hike, shading you from the sun and providing a welcome sense of isolation from the din of suburban noise around you.

Spring grasses

The single track trail that you’re traveling on will dive in and out of the woods, connecting with the main trail for brief stretches. As the side trail is only ever marked with anti-mountain biking signs, it can be a little disconcerting to venture onto them, especially if you’re not certain where they might lead. Trust them. The only places they will lead will either be to the handful of creek crossings or back to the main trail. You will not get lost here, and as long as you stick to the trail and don’t wander off, you will have a lovely experience.

Early evening sun

One thing to be aware of is that with the generous amount of oak trees will come an equally generous amount of poison oak. If you are unable to recognize the shiny, bright green (or reddish in late summer and fall) leaves, you should make it a priority before attempting this hike. Remember the old adage, “Leaves of three, let it be.” Also know that poison oak prefers cool, shady spots beneath oaks, where it will grow like weeds beneath the trees on either side of the narrow trail. This isn’t necessarily a concern, as you’d have to go off trail to encounter it. However, poison oak can also grow as a vine up into trees and off of the branches. Occasionally, a poison oak vine will separate from the tree and emerge at chest, shoulder, or even head height on the trail. While it is tempting to become lost in a revery on this trail, please remain at least somewhat mindful lest you inadvertently get a face full of poison oak. This is not a frequent hazard here, but as it does exist, you should remain aware.

Mule deer

As you follow the meandering trail through dense groves of oaks and sycamores, punctuated by small meadows, patches of cactus, and occasional glimpses of creek, you will frequently experience the sensation that you have left San Diego and wandered somehow into a swamp-like environment. The word “riparian” refers to growth supported by watercourses. The more water, the more growth, and as the creek is so reliable, so too are the woodlands. It is rare to find growth as dense as this in San Diego. The trail itself is remarkably flat, and the combination of easy, flat hiking and dense trees makes the first 2.5 miles of this trail a delight.

Peñasquitos Creek

At 2.5 miles, the trail emerges from the woods and re-connects with the main trail at a junction called Carson’s Crossing. This is a worthy side-trip as the crossing may be the most beautiful spot in the preserve. A pair of wooden bridges cross over the creek as it divides into separate channels. In the midst of these channels is a sandy bank shaded by mature oak trees. The creek slows and collects into a large pool by which one can sit and read or simply soak in the sound of birds singing and frogs croaking. The peace is not absolute as mountain bikers frequently cross over the bridge and throw their loud conversations into the mix. However, they come and go quickly, only occasionally punctuating the peaceful scene before you. If you share my general indifference toward waterfalls, this is a good place to stop and rest before turning back, allowing a 5 mile round trip hike.

The top of the waterfall

However, if you find waterfalls inspiring, trace your way back to the main trail and follow it as it climbs a low rise. There, you will find a large volcanic rock outcrop seemingly out of place in this grassy, gentle landscape. This volcanic rock was exposed by the creek, although it is much slower to erode than the surrounding sandstones. The creek tumbles of the outcrop forming a small waterfall that is somewhat difficult to view head-on due to the lack of access to a frontal view. Be careful climbing about here, as there are a number of drops that could cause injuries. Part of my indifference toward waterfalls is that they seem to seduce people into doing foolhardy things like climbing rocks that should not be climbed. Be careful here, while enjoying this open, sunny spot serenaded by singing cascades.

Peñasquitos Falls

This point marks 3.2 miles in and is a fine place to turn around and return. You are, of course, welcome to continue on the trail, which will continue for another 2.8 miles to the west trailhead, making a 12 mile round trip track. This 12 mile hike is an excellent hike for runners seeking to practice for long-distance trips. It’s also a fine hike, although the scenery on the west end is not as nice as that on the east end. Should you feel satisfied, re-trace your steps back along the creek until emerging back at the trailhead.

Inner trail during February

Things you should know:

– The gate to the parking lot is open from 8am to 6pm. This is unfortunate as not only is the trail open earlier and later, but the finest times to hike here are before sunset and after sunrise. Should you wish to extend your hike a little later, you can park at nearby Peñasquitos Park on the north side of the creek. You’ll add another .3 of a mile, but you’ll have more time. I highly recommend paying the day use fee anyway as your fee money goes toward maintaining the park and removing invasive species like wild fennel.

Great review! Just did this trail yesterday for the first time. People should note that the terrain can be quite painful for those of us with arthritis. My 13 year old daughter and I (both with Rheumatoid Arthritis) were struggling on the hike and are quite sore today because of the soft soil and rocky paths.

I recommend trekking poles for people with chronic pain (though even my trusty poles did not keep me steady or pain-free). I also recommend starting on shorter hikes and working up to the longer one to the waterfall. It is totally worth the pain because it's such a lovely hike, but proceed with caution (we even found this trail harder than the BFI at Crystal Cove in Laguna Beach).

Thanks for your reviews. I always check them before heading out on a new hike!

Hello Scott,
I think that the gate on the east end is open until 8pm in the summer months. Just hiked it today and saw a good amount of poison oak as well. Thanks for the write up!

Whups! Bad typo! The gate is OPEN 8am to 6pm. I'll get that fixed this evening.

Is the gate really closed 8 am to 6 pm, i.e. all day? Or did you mean 8 pm to 6 am?
