The Turtle Rock Nature Center is located at the base of the San Joaquin Hills in the City of Irvine, and serves as a community resource for environmental interest and concern. The five-acre nature preserve is both a home for wildlife and an outdoor classroom where visitors and program participants learn to protect our natural environment. Visitors can explore the nature center at their leisure, taking a self-guided trail walk during regular operating hours. Trails may be closed due to inclement weather.
