Located approximately 1/4 mile on Highway 96 from the Highway 299 intersection in the town of Willow Creek, Big Rock offers day use for those who want to spend the day on the Trinity River. It is a popular spot in the summer months for swimming, sunbathing, picnicking and just relaxing. This site offers river access to fisherman and non-motorized boaters wishing to float the lower section of the Trinity River. It contains shaded picnic areas for those wanting to enjoy the river scenery out of the sun. There are two vault toilets for the convenience of river-bound visitors, and offers a place for those needing a break from the road.
