Protect One of Rancho Cucamonga's Natural Attractions

Summer is here and so is the busy season at the North Etiwanda Preserve.


The North Etiwanda Preserve has many visitors all year long, but the summer season is the busiest. The Rancho Cucamonga Police Department wants to ensure everyone who visits the Preserve is safe, which is why the rules and regulations set by the San Bernardino County Special Districts Department are closely followed and enforced.

The North Etiwanda Preserve is managed by the San Bernardino County Special Districts Department and our City staff and law enforcement are proud to contribute to its work ensuring visitors have a safe, enjoyable experience. The Preserve has limited parking and amenities because it is not a park. Parks provide a recreation space for people, parties, sports, and playgrounds while preserves allow nature to thrive and protect it from destruction.

Those found inside the Preserve during closed hours are subject to citation and vehicle towing. Please make sure to park in a designated parking area and not in a "No Stopping" zone. Any other locations are subject to vehicle code and municipal code enforcement. Vehicles are not allowed to park south of the entrance parking gates, including the dirt area east of Etiwanda Avenue, which is private property. Keep an eye out for the many visible "No Stopping" and "Parking Violators" signs posted along Etiwanda Avenue.
