Annie's Canyon Trail: My Local's Guide to San Diego's Slot Canyon Hike
Dorthy Routt Millsap·May 25, 2026·5 min.
Annie's Canyon Trail is one of those hikes that doesn't feel like anywhere else in Southern California. My local's guide to this slot canyon near Encinitas.
Annie's Canyon Trail is one of those hikes I love sending people on, because it doesn't feel like anywhere else in Southern California. You squeeze through narrow sandstone walls, climb a metal ladder, and pop out at an overlook with Pacific Ocean views — all just minutes off I-5 near Encinitas. It sits inside the San Elijo Lagoon Ecological Reserve, and it was actually off-limits for years before reopening as the little adventure it is today.
The full hike runs 1.8 to 2.4 miles with 426 to 470 feet of elevation gain, and takes about 1 to 1.5 hours. It's a moderate trail, open year-round. Here's everything I'd tell a friend before they go.
If you only read one section, make it this one:
There are three ways in, depending on where you start:
Most people finish in 40 to 60 minutes, though it's easy to stretch it to 90 with photos and breaks. Access is free, and the trail is open sunrise to sunset, year-round.
A few things worth knowing up front. Dogs are welcome on leash throughout the reserve, but not in the slot canyon itself — the narrow passages and ladder just aren't safe for them. And while the overall trail is rated easy, the slot canyon section is the exception: it's a real scramble, requiring you to climb and pull yourself up through tight spaces before the ladder spits you out at the top.
You've got a few options here, which is nice on a busy day.
North Rios Ave is the most popular starting point. From San Diego, take I-5 North to exit 37 (Lomas Santa Fe Dr), turn left, go about 4 miles, then turn right on N Rios Ave. The trailhead is at the end of the street. There's no lot, so you'll park along the residential street.
The San Elijo Park & Ride on Manchester Ave is the newest option and has the most reliable parking. From the lot, cross Manchester at the crosswalk and take the pedestrian suspension bridge under the freeway heading south. Turn right on the North Coast Trail, veer right at the Y onto Solana Hills Trail, then take the first right at the T onto Rios Avenue Trail.
You can also find street parking along Solana Hills Drive and Canyon Drive, or use the La Orilla Trail dirt lot if you want a longer walk. It's all free — just arrive early on weekends, because spots go fast.
The first stretch is the easy part. The path winds flat through the ecological preserve along the wetlands, with benches to pause at before you reach the canyon. About half a mile in, you'll hit a split: the slot canyon route, or the easier switchback trail.
Take the slot canyon. It starts wide, then narrows after the first bend. From there, you'll turn sideways to fit through walls barely wider than your body, use both hands to pull yourself up through sandy terrain, and crawl on hands and knees in a few spots. This is why you leave the big backpack behind — there's no room for it. And remember the canyon is one-way: if you turn around, everyone behind you has to back out single file.
At the end comes the signature moment — a metal ladder with three flights and platforms between each section. It sounds intimidating, but the handles make it manageable even if you're wary of heights. A few steep steps follow, and the final step out of the canyon is hip-high for most people.
Then you're at the overlook, and it's worth every squeeze: the Pacific Ocean, the Central Basin, and eroded sandstone formations that look a lot like Torrey Pines. From here, the switchback trail makes for an easy walk back down to where you started.
Absolutely — as long as you come prepared for the tight squeezes and the ladder. Park along North Rios Ave for the shortest route, or use the Park & Ride if it's a busy weekend, and go on a weekday morning if you can swing it. The ocean view at the top makes every awkward shuffle through the canyon worth it.

How challenging is the Annie's Canyon hike?
It's rated moderate, with some strenuous sections. The walk in is easy, but the slot canyon is the real work — climbing, squeezing through narrow passages, pulling yourself up through sand, and a three-flight ladder at the end. A few spots are tight enough that you'll turn sideways or crawl.
Are there restrooms at the trailhead?
No — there are no restrooms at any of the trailheads or along the trail. Plan ahead, since the round trip runs about 1 to 1.5 hours.
How long is Annie's Canyon Trail?
It depends on your trailhead. The hike ranges from 1.8 to 2.4 miles round trip, with the shortest route being 1.4 miles via Rios Avenue. The slot canyon is only about 0.25 miles of that — the rest is flat, scenic walking through the preserve.
Where do I park?
The most popular option is street parking along North Rios Avenue. The San Elijo Park & Ride on Manchester Avenue has more reliable spaces, and you'll also find street parking along Solana Hills Drive and Canyon Drive. It's all free, but arrive early on weekends.
Can I bring my dog?
Dogs are welcome on leash throughout most of the reserve, but not in the slot canyon itself. The narrow passages and ladder make that section impractical and unsafe for pets.
A 0.6-mile cliffside trail next to the Cave Store delivers Amalfi Coast views over La Jolla Cove. Free, easy, dog-friendly, and probably the best 15 minutes in San Diego.
