McGrath State Beach Campground offers 174 campsites with full facilities (flush toilets, hot showers, drinking water, dump station) adjacent to the Santa Clara River Estuary, making it ideal for bird-watching and wildlife viewing with over 245 bird species.

Beach access is limited due to flooding and habitat protection, requiring approximately a half-mile walk around an inland lagoon to reach the shore.

The campground is subject to seasonal closures due to winter flooding, so visitors should call ahead to confirm availability before planning trips during fall and winter months.
