McGrath Hike and Bike Campground offers 174 developed campsites with picnic tables, fire rings, and restrooms with hot showers, plus a dedicated hike-and-bike site for cyclists and backpackers.

Located between the Pacific Ocean and Santa Clara River estuary near Oxnard, it provides easy beach access and excellent bird-watching opportunities in a natural wetland setting.

Note that the campground occasionally closes during winter due to flooding, and swimming is discouraged due to strong rip currents; the area is better suited for beach walks, fishing, and wildlife viewing than water sports.
