The Cuyamaca Rancho State Park Interpretive Association center is located between Paso Picacho and Green Valley Campgrounds on Hwy 79. Just follow the signs that say Park Museum or walk there on the Cold Stream Trail. The Visitor Center houses the Park's Museum which contains displays and exhibits about the Park's history and wildlife. The Visitor Center is open Saturdays and Sundays from 10:00-4:00.

The Cuyamaca Rancho State Park Interpretive Association (CRSPIA) supports the mission of California State Parks, Cuyamaca Rancho State Park and Palomar Mountain State Park through education and interpretive activities that enhance the visitor’s experience.

CRSPIA accomplishes its goals principally through fundraising and supporting interpretive programs. Support is also provided for the parks’ volunteer groups, which include the Interpretive Assistance Unit, the Mounted Assistance Unit, the Mountain Bike Assistance Unit, and the Trails Maintenance Unit.

Historically, CRSPIA has passed along to park programs 95% of all funds received from the public. Sources of funds include profits from the operation of a gift shop and bookstore, sale of firewood, membership dues, and various fundraising events.

Over the last decade, revenues have grown steadily to the current level of approximately $90,000 per year. Members receive a monthly newspaper, “The Stonewall Sentinel.” Your membership in Cuyamaca Rancho State Park Interpretive Association, or donation to the association, will help effectively support the visitor-serving activities of the Department of Parks and Recreation at two premier southern California units, Cuyamaca Rancho and Palomar Mountain State Parks.
