Annie's Canyon Trail
Our pickMost coastal walks in San Diego give you water views. Annie's Canyon gives you walls. Where Solana Beach meets San Elijo Lagoon, a trail slips into a true slot canyon, with narrow sandstone walls hugging you on both sides, then lets you out on top with the Pacific and the lagoon spread out below. It's free, it takes about an hour, and nothing else in town feels like it. That's why it's number one.
Nature Collective, the nonprofit that cares for the lagoon, lists three ways in. The Rios Ave route is the shortest at about 1.4 miles, the Solana Hills route runs about 1.6, and Via Poco about 2. The walk starts out paved and easy, then turns to loose sand and uneven ground. The slot has ladder-style stairs, and at a few points you'll use your hands as well as your feet to scramble up. It runs one way, so everyone comes back down by the switchbacks, a stretch of wooden-plank stairs that covers about 300 feet of elevation in a quarter mile. Nature Collective rates the hike easy with strenuous portions and puts it at 40 to 60 minutes. Short and steep is a fair summary.
Up top, the view takes in the ocean and the lagoon's Central Basin. On the way through, look closely at the canyon walls, where you can read maritime terraces and the slow work of erosion. The lagoon around you is a 915-acre ecological reserve with roughly 300 bird species on record, so binoculars earn their space in the bag. Fans of the trail point to exactly this mix: the slot itself, the lagoon views, the strange geology, and a distance short enough for kids.
The popularity is the part to plan around. The passage is single-file, so on busy mornings you wait your turn, and parking near the trailheads can be tight. Go early, before the line builds and before the exposed approach warms up. Leashed dogs can use the lagoon trails but can't enter the slot, and there are no bikes and no restrooms. The narrow sections can feel tight, so give anyone who's claustrophobic a heads-up. There's also a scenic way in from the north: from the San Elijo Activity Hub Park & Ride, a paved path follows the restored lagoon, and a suspension bridge under the I-5 crosses to the canyon side of the channel.
