San Elijo Lagoon and Ecological Reserve is a coastal wetland in Cardiff, between Encinitas and Solana Beach. More than seven miles of trails cross marsh, woodland and coastal scrub, with chances to spot migrating birds, reptiles and other wildlife. Stop at the nature center for local plant and animal exhibits, including live snakes. For a more demanding walk, Annie’s Canyon Trail climbs through narrow sandstone passages to a viewpoint over the lagoon and Pacific Ocean. Several shorter trails suit an easy walk with children or a dog.
Trails through the wetlands

The reserve covers nearly 1,000 acres of coastal wetlands, with more than seven miles of trails linking different parts of the landscape. Routes pass through salt marsh, freshwater and brackish marsh, riparian woodland and coastal sage scrub. Short loops start near the nature center, while longer walks connect across the lagoon.
Some paths have accessible sections, and the range of routes makes it possible to choose a shorter outing or spend longer exploring. Trail conditions can change after rain, so check the park’s current information before setting out.
Birdlife and the nature center

The lagoon is a stopover for migrating birds and a habitat for shorebirds and other wildlife. Keep watch along the trails for birds, fish, reptiles and small lizards. The nature center has educational displays about the local ecosystem, taxidermy animals and live snakes, as well as activities for children.
For a closer look at the birds moving through the area, ask at the center what has been seen recently. Children can also take part in TRACK Trails, a nature-themed scavenger hunt with an online prize component.
Annie’s Canyon Trail
Annie’s Canyon is a short loop through naturally formed sandstone walls and narrow passages. The route climbs steeply, with switchbacks and stair sections, to a viewpoint above the lagoon with views toward the Pacific Ocean. It is a more strenuous choice than the reserve’s gentler paths, and the narrow sections may not suit every visitor or dog.
The canyon trail connects with routes through the reserve. One option is to walk from the nature center toward the Pole Trail and continue across the lagoon; Annie’s Canyon is about two miles from the center by that route.
Planning a visit
There is no shade on many of the trails, so cooler parts of the day are more comfortable. Bring water and refill at the entrance, where water is available. The main parking lot is free but limited; parking across the street may be an alternative.
Dogs are allowed on trails, though hot conditions and the steep, narrow sections of Annie’s Canyon are worth considering before you go. The reserve is for walking and running, and the trails are not for cycling. Check the park website for current trail information and any closures after rain.
