The largest saltwater marsh between the Monterey Bay and the Tijuana River Estuary, the Bolsa Chica Ecological Reserve in Huntington Beach covers 1,400 acres of fresh and saltwater wetlands habitat, a boardwalk over the marsh, and five miles of easy trails through the lowlands and mesas. Over the years it’s become the happy place of birders, hikers, runners, and nature lovers alike. Let’s explore.

Bolsa Chica Walk


With more than 8,000 years of human history in Bolsa Chica, the area holds the memories of the first Californians, the Tongva. Throughout history it has preserved its natural habitats while embracing modern developments, like a Pacific Electric Railway “Red Car” stop, the Bolsa Chica Gun Club, and underground army bunkers during World War II. Nowadays, the pocket represents the culmination of a decades-long effort by activists who battled to protect the wetlands ecosystem from development.

When visiting the reserve, explorers must note that dogs and bicycles are not permitted, and must stay on paths to protect sensitive nesting areas. Cameras and binoculars are welcome!

Enter at the Bolsa Chica Wetlands Interpretive Center (3842 Warner Avenue) or the Boardwalk Loop Trail (18000 Pacific Coast Highway) to hit the trails and take in the breathtaking natural scenery. Located along Warner Avenue near the corner of Pacific Coast Highway, the Interpretive Center serves as home base to the five miles of trails. For the Boardwalk Loop Trail, park at the south parking lot along Pacific Coast Highway across from the entrance to Bolsa Chica State Beach and walk the 1.5-mile loop trail along the boardwalk over the marsh, stopping to read the informational signage.

A stroll or jog along the dirt trails through the lowlands and mesas affords sightings of feathered friends like hawks and herons, furry inhabitants including coyotes and rabbits, scaly residents such as snakes and lizards, and marine life like fish, sharks, and rays.  

Flora lovers can explore five major plant communities, including salt marsh, coastal strand/sand dune, coastal sage scrub, freshwater wetlands, and riparian woodland.

Birders flock here in hopes of spotting some of the more than 300 bird species known to the area, including great blue herons, western snowy plovers, ospreys, red-tailed hawks, and burrowing owls. The wetlands are an important migratory stop and nesting ground for our winged friends, and the best seasons for spotting are winter (November-February) and summer (April-August).
