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.

Video and Turn-by-Turn Directions for Annie's Canyon Trail
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...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.

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.
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
It's crucial that you stay on the trail and don't venture off into sensitive habitats or deadly parts of the slot canyon.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.There are green signs located along the trail to point you in the right direction.There are also a liberal amount of benches located along the trail if you want to take a break and soak up the views.
If you bring a dog or toddler, you'll probably have to carry them up some of the ladders in the slot canyons.
The canyon gets narrow and you may have to walk sideways. If you are claustrophobic, you could have problems in the narrow section.
The canyon trail is one-way (up), so you don't have to worry about passing people in the other direction.
This is a popular hike. Arrive early or visit on a weekday to beat the crowds.
The Annies Canyon Trail Story
Today Annie's Canyon Trail is a well-marked, clean and beautiful trail. However, it used by covered in graffiti and a hangout for those looking "to party." Photo Jerome Lucido
Millions of years ago, this whole area was underwater.
When the area here became land, runoff from the surrounding area eroded the sandstone, which deepened them over the years into the canyons that you see today.
Up until 2015, this area was all private property, but often trespassed on. Vandals would spray paint the walls. People used the area to get high and party.
In 2014 a popular website, Hidden San Diego, published a story about the canyon, and visitation to the closed area skyrocketed. The local conservation community knew they had to address the issue.
A long-time San Elijo Lagoon Conservancy supporter named Annie made a generous donation to acquire the land. Several volunteer groups removed the graffiti and built the trail, which officially opened in 2016 as "Annie's Canyon."
Go through the gate at the end of the street.You'll see some trail signs when you go through, confirming that you are in the right place.Follow the wide trail as it climbs.At the top of the hill you'll pass the Canyon Trailhead on the left. Go straight and downihill.Follow the trail downhill along I-5. Avoid any unofficial side trails and stay on this main, wide trail along the highway.The trail will come close to the highway. Our turnoff comes shortly, once the trail dips below the level of the highway.Look for a small side trail on the left, about 0.5 miles into the hike.Enjoy the shade of the small trail as you hike away from the highway.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.

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).Go straight along the wall on the right.And then you're in the beginning of the slot canyon!Stay out of the side canyons.Make the left to enter the narrower part of the canyon.In the beginning you can walk head-on.But then it narrows even more; you may have to walk sideways.When you get to the split, make the short detour to the grotto of the mushroom cave.Here's the mushroom cave. You can still see remnants of the old graffiti on the ceiling.After the cave, head back to the trail and continue up the ladders.At the top of the ladders you have a little more canyon left.And then you arrive at the top and end of the canyon.Enjoy the nice views to the Pacific Ocean from the bluff, and then head downhill.The steep trail has some small switchbacks to make the descent (and climb) more manageable.At the junction at the bottom, make the right to head back to the junction with the big trail board.If you want to head back to the start, just make the right and retrace your steps.

I also share what hiking gear works and doesn't so you don't waste money. I don't do sponsored or promoted content; I share only the gear recommendations, hikes, and tips that I would with my family and friends.
