Annie’s Canyon Trail is about as unique as they come. On this short hike, you’ll be able to experience a sandstone slot canyon, complete with narrow walls and ladders. And on the way to the canyon, you’ll get beautiful views of San Elijo Lagoon Ecological Reserve, a critical migrating waterfowl habitat. Another bonus on this hike is that it’s only minutes off of Interstate 5, making it an excellent leg-stretcher hike stop if you’re driving past.

Locals also know Annie’s Canyon Trail as the “ACT” or “mushroom caves.”

Where is Annies Canyon Trail?

There are a half-dozen trailheads and ways to get to Annie’s Canyon Trail; in this guide I’ll show you how to get there from free and abundant street parking, just off of the I-5. Use this trailhead address:
Solana Hills Trailhead, 498-450 Solana Hills Dr, Solana Beach, CA 92075

When you get to the destination, you’ll see a dead end. The trail starts at the end of the street. Just make a u-turn and…
Annies Canyon Trail Directions 6
Park along the side of the street. It’s mainly open parking, but double check for no-parking areas and driveways.

There are no restrooms at the trailhead or on the hike.

Gear For the Hike

This is a short and easy hike, and you don’t need anything special to do it. Expect to get sandy, and if you have a backpack, it will be hard to get through the slot canyon. If you simply carry a small water bottle and wear casual fitness clothes and sneakers, you’ll be great.

Lone Peak 5

Altra Lone Peak 5
For most people, the Altra Lone Peak is a solid choice that will leave your feet feeling great at the end of any hike. The feel is cushy and light, and if it had a car equivalent, this would be a Cadillac or Mercedes Sedan. The grip is great and they’re reasonably durable for this type of trail runner, which I think is better in most conditions than a hiking boot, and here’s why. The downside of this shoe is that it won’t last as long as something like the Moab 2 (see alternate footwear choices at the bottom of my gear page). I’ve been using mine for many miles and my feet always feel great. Watch my video explaining why they are a great shoe here.

Garmin Inreach Mini Beacon

Stay Safe Out of Cell Phone Range
If you’re not familiar with the Garmin InReach technology, it allows you to send and receive text messages where you don’t have cell phone signals. You can also get weather reports and trigger an SOS to emergency responders. Even if you don’t have an emergency, sending a quick message telling a loved one that you’re okay or are running late is well worth the cost. The Garmin InReach Mini (REI | Amazon | My Review) fits in your palm and weighs next to nothing.


Gaia GPS Mapping App
Smartphones are not backcountry instruments, but almost everyone has one today. And they all have GPS onboard. So I recommend getting a good GPS hiking app like Gaia GPS that supports offline maps. Just make sure to put your phone in airplane mode so the battery doesn’t drain. GaiaGPS not only has smartphone and tablet apps, but also an online planning tool. You can drag the GPX hike tracks from my (or any) guides into the online map and they will sync to your phone. You can also check for wildfires, weather, snow, and choose from dozens of map types with a premium membership (HikingGuy readers get up a big discount here). Note that I also carry a paper map with me in case the phone dies or gets smashed.

Here’s my complete gear list that I personally use, have tested, and recommend, updated September 2021.

Annies Canyon Trail Maps

The hike from the trailhead through Annies Canyon is 1.8 miles. I’ve added an optional and short loop extension that lets you take in more of the shores of San Elijo Lagoon Ecological Reserve, which adds another 0.7 miles to the total.

Fenix 6 Pro

How are you going to navigate this hike?
To start, you should always have a paper map and compass. And it helps to print this guide out or save it on your phone. I highly recommend a GPS as well. I use the Garmin Fenix 6 Smart GPS watch ( REI | Amazon | My Review) with maps (or the more affordable Garmin Instinct). The GPS smartwatch is nice because it’s rugged, works if your phone dies, and also has a billion other features like sleep tracking, workout recording, etc.

The hike starts at the parking area next to I-5, then winds into the lagoon before reaching the short Annie’s Canyon loop. The optional blue line is a nice extension around the shores of the lagoon, which rejoins the trail you came in on after 0.7  miles.

Trail Notes

Annies Canyon Trail Directions 4
It’s crucial that you stay on the trail and don’t venture off into sensitive habitats or deadly parts of the slot canyon.
Annies Canyon Trail Directions 5
I wish I could say this is common sense, but I need to say it. Don’t scratch or scrawl onto the soft cave walls like these knuckleheads did.
Annies Canyon Trail Directions 3
There are green signs located along the trail to point you in the right direction.
Annies Canyon Trail Directions 2
There are also a liberal amount of benches located along the trail if you want to take a break and soak up the views.

At the top of the hill you’ll pass the Canyon Trailhead on the left. Go straight and downihill.
Annies Canyon Trail Directions 11
Follow the trail downhill along I-5. Avoid any unofficial side trails and stay on this main, wide trail along the highway.
Annies Canyon Trail Directions 12
The trail will come close to the highway. Our turnoff comes shortly, once the trail dips below the level of the highway.
Annies Canyon Trail Directions 13
Look for a small side trail on the left, about 0.5 miles into the hike.
Annies Canyon Trail Directions 14
Enjoy the shade of the small trail as you hike away from the highway.
Annies Canyon Trail Directions 15
You’ll start to get some views of San Elijo Lagoon.

The Spanish expedition that visited the area in 1769 originally named the area San Alejo Lagoon. Over the years, before there was a strong written record, people mistakenly called it San Eligio (the patron saint of goldsmiths). The bastardization of the word continued into its current form, San Elijo, which is not actually a saint.

Annies Canyon Trail Directions 16
Stay straight on the main trail as a side trail joins from the right.
Annies Canyon Trail Directions 17
And a second after that, another trail joins from the right. Hike straight.
Annies Canyon Trail Directions 18
When you get to the big junction with the trail board, make the hard left to enter Annie’s Canyon.
Annies Canyon Trail Directions 19
Go past the big Annie’s Canyon Trail sign.
Annies Canyon Trail Directions 20
Make the right at the split to enter the slot canyon.
Annies Canyon Trail Directions 21
Here’s the sign at the junction. If you don’t want to do the slot canyon, you can hike up the switchbacks to the left. And remember that if you do the slot canyon, it’s one-way (going up).
Annies Canyon Trail Directions 22
Go straight along the wall on the right.
Annies Canyon Trail Directions 24
And then you’re in the beginning of the slot canyon!
Annies Canyon Trail Directions 23
Stay out of the side canyons.
Annies Canyon Trail Directions 25
Make the left to enter the narrower part of the canyon.
Annies Canyon Trail Directions 26
In the beginning you can walk head-on.
Annies Canyon Trail Directions 27
But then it narrows even more; you may have to walk sideways.
Annies Canyon Trail Directions 28
When you get to the split, make the short detour to the grotto of the mushroom cave.
Annies Canyon Trail Directions 29
Here’s the mushroom cave. You can still see remnants of the old graffiti on the ceiling.
Annies Canyon Trail Directions 30
After the cave, head back to the trail and continue up the ladders.
Annies Canyon Trail Directions 31
At the top of the ladders you have a little more canyon left.
Annies Canyon Trail Directions 32
And then you arrive at the top and end of the canyon.
Annies Canyon Trail Directions 33
Enjoy the nice views to the Pacific Ocean from the bluff, and then head downhill.
Annies Canyon Trail Directions 34
The steep trail has some small switchbacks to make the descent (and climb) more manageable.
Annies Canyon Trail Directions 35
At the junction at the bottom, make the right to head back to the junction with the big trail board.
Annies Canyon Trail Directions 36

Annies Canyon Trail Directions 40
Enjoy the lookout shortly after the turn.
Annies Canyon Trail Directions 41
And then continue straight along the side of the lagoon. The tide comes in and out twice a day. When it’s high, look fr marine creatures in the shallows. When it’s out, look for birds searching for food in the mudflats.
Annies Canyon Trail Directions 42
The trail turns inland when it approaches the highway. As you gently climb, look up and to the right to see the top of Annie’s Canyon.
Annies Canyon Trail Directions 43
Stay on the trail as it widens.
Annies Canyon Trail Directions 44
And soon you’ll be climbing up along the interstate on the trail you came down. Follow it straight along the highway back to the parking area.
