San Elijo Lagoon Ecological Reserve

San Elijo Lagoon Ecological Reserve

San Elijo Lagoon is one of the largest remaining coastal wetlands in San Diego County, and home to an exceptional number of plants and animals.

A walk along more than seven miles of trails will take you through various plant communities where you’ll encounter many of the 300 species of plants, 16 species of reptiles and amphibians, and 26 species of mammals.

The lagoon is especially known for its bird life. At least 300 species have been seen here, 76 of which are classified as sensitive.

The “green” nature center located on the north side of the lagoon offers exhibits that detail the lagoon’s plant and animal communities, its fascinating history, and the various natural and human influences that affect this sensitive ecosystem.

As an Ecological Reserve, San Elijo Lagoon has no developed facilities on the southern trails. However, restrooms and water are available at the Nature Center.
