A beautiful hike in the coastal mountains. Phenomenal flower blooms in the spring, strong sun in the summer, and a small spring and waterfall (during wet years), the main attraction are large swaths of native California grassland — some of the last remaining unspoiled areas in the state. A well-traveled area with lots of trail options can make this area and easy couple of hours or a full day excursion.

La Jolla Canyon was one of the first hikes I did when I started “taking hiking seriously.” I remember two things — one, that it was gorgeous, and two, that it was about 100 degrees out and the trail had a total of four shaded areas. I don’t think I’ve ever been covered in more sweat. And so, on a hot, sunny weekend, I figured this would be an appropriate reintroduction to hiking, after being forbidden by my doctor for over a month.

After a long and relaxing drive down the Pacific Coast Highway, you’ll enter Ventura County and pass the so-called “Great Sand Dune.” Across the street from Thornhill Broome Beach is the entrance to La Jolla Canyon. It’s a popular trailhead and a nice campground, too – so it’s very clearly marked.

Park on the PCH or in a small lot inside the park. When you see the gate posted with ominous signs about ticks and mountain lions, take the small trail to your immediate right — the Ray Miller Trail.

This trail will slowly wind and switchback its way up the mountain, in full view of the Pacific. Its 2.7 miles — like the rest of the trail — are not shaded, but it’s nice to get the bulk of the elevation gain done with at the beginning of the journey.

And while you’re climbing the trail, you’ll have plenty to look at — especially if it’s spring time. This place is absolutely teeming with wildflowers and the animal life that goes with it. Lillies, yuccas, and poppies were blanketing the sides of the path, while swarms of ladybugs and honeybees filled the air.



On this trail, it’s tempting to keep your eyes glued to the ground to try to take in all of the colorful blossoms and blooms, but it’s also worthwhile to look up every now and then. You’ll be rewarded with sweeping vistas of the Pacific and the rugged Santa Monica mountains surrounding you.


The Ray Miller Trail ends when it intersects with the Overlook Fire Road. Turn left to continue north on this broad fire road as it continues a gradual ascent along a ridge. To the southeast, you’ll have great views over the wide Big Sycamore Canyon with some of the more angular coastal mountains in the distance.

It’s another two miles from the Ray Miller Trail junction to a five-way intersection to the north. As you hike the mostly-level route, you’ll get your first glimpses inside the La Jolla Valley Nature Reserve, with its unspoiled landscape and large patches of grassland. From up here, they just look like green swatches amidst the chaparral — but in just a short distance, you’ll get to see them in much greater detail.

At the intersection, take La Jolla Valley Fire Road west, back toward the trailhead. After just .2 miles, the trail splits again. If you want to explore the entire valley, bear to the right. This path travels past three trail camps through tall grasslands before returning to the main trail or climbing the ridge of Mugu Peak (this side route adds 2.8 miles to the trip). If you’re pressed for time, or just want to meander through the grass, bear left and onto the La Jolla Canyon Trail — right away, you’ll find yourself walking through thigh-high grass.


If you take the trip later on in the summer, this sea of green will turn golden — and will give you an idea of what Ms. Bates was thinking of when she wrote about “amber waves of grain.”

Regardless of the season and your current levels of musical patriotism, this is probably a good place to make frequent tick checks.

The trail continues south, passing a small, swampy pond along the way. When I did this trail a few years ago, the water was flowing up and over the trail itself, but this time, the pond was nearly empty. It is enough water to nourish large clusters of poison oak, though, so watch your arms and legs while trekking. But this is by far the shadiest stretch of the entire route — so if it’s hot and sunny out, be sure to enjoy it.

From here, the trail stays to the south of a creek bed (which may be bone dry) and follows it back to the trailhead, through an area of relatively narrow canyon walls. There are a few steep sections, and one area that was destroyed by a recent landslide, but everything is easily passable. If you’re lucky enough to have water flowing, you will even be treated to a small waterfall. Otherwise, just enjoy the canyon walls and large groves of Giant Coreopsis–the odd, slightly melted-looking perennial native plant that is especially prevalent near the canyon’s mouth. In the spring and early summer, their eye-catching bunches of bright yellow blooms provide a unique ending to your journey.


In no time, you’ll find yourself back at the trailhead. If it’s during the warm months, you’ll probably be out of water and covered in sweat. Although the ocean is tantalizingly close, the beach right across the PCH from the trailhead is all rocks. There are plenty of unnamed beaches on the way back south toward L.A. Just pull your car over on the side of the road and crawl down the rocks to chill out in the sand and cool water. It’s a great way to cap off the day.

  • We just heard the La Jolla Canyon Trail is washed out near the waterfall and access is closed for the time being. The only ways to get into the valley are via the Ray Miller Trail and Chumash Trail further north along the PCH.

  • Lydia Elise says:

    I camped here last week, entering the valley from the Chumash trailhead. The campsites are really nice and the flowers and birds right now are heavenly. I heard many frogs and owls all night and saw several butterflies and hummingbirds. Wildflowers are in full effect all over the valley right now for anyone interested! So gorgeous, I think I will go back when it warms up again to hit the other trails in the area.:)

    • Megan says:

      Did you leave your car parked in the lot at the trailhead? I was told it was no overnight parking.

      We went to hike in on La Jolla Canyon but that trail has been closed since January. So we drove up to Chumash but the parking was vague.

    Thanks again! Just finished this hike today (April 2nd) and it was beautiful. Keep in mind that the views can be beautiful, but depending on the time of year, it can be very cloudy/foggy and chilly. So visibility can be minimal…which was the case for today and man did I love it. Light breeze rolling up the hills off the coast with rolling clouds. It was so peaceful and relaxing. So the clouds did all the shading for me! Excellent hike. Strongly recommended.

    This is my favorite hike in Ventura County. I needed information about La Jolla Cyn for a friend when I stumbled upon your blog. Excellent work, thanks for sharing!

  • Judith says:

    Your site is excellent, the photos are beautiful and your Google trails make me want to hop on a plane and visit. Obviously it is a labour of love for you. Congratulations on lovely work!
