San Luis National Wildlife Refuge

San Luis National Wildlife Refuge is a protected area spanning about 26,600 acres of wetlands, riparian forests, native grasslands, and seasonal pools across California's San Joaquin Valley. These diverse habitats support waterfowl, deer, and numerous other wildlife species throughout the year.

This refuge was established in the mid-twentieth century as part of federal efforts to protect migratory birds during their winter stays and prevent conflicts with farming activities. The protection of these wetlands became urgent as agricultural development threatened their survival.

The refuge serves as an outdoor classroom where visitors learn about the relationships between water, plants, and animals in wetland ecosystems. Local communities connect with nature here and understand why these habitats matter for the region's wildlife.

The refuge operates year-round with a self-guided auto route and multiple nature trails available at no entrance fee. Visitors should bring binoculars and plan visits during early morning or late afternoon hours when wildlife is most active.

The refuge maintains a protected herd of tule elk, a deer species that once faced near extinction. This successful recovery demonstrates how protected areas can bring endangered species back from the brink of disappearing.
