- Arroyo Conejo Open Space covers 302 acres.
- A trail-access point is at Rancho Conejo Playfield, near the intersection.
- Open-space trails are generally open from sunrise to sunset, with closures possible during inclement weather or emergencies.
Where is Arroyo Conejo Nature Preserve?
Arroyo Conejo Nature Preserve sits within Arroyo Conejo Open Space, northeast of the intersection of Hillcrest Drive and Ventu Park Road in Newbury Park, California. The broader open space covers 302 acres and includes the preserve, also known as the “barranca.”
The area’s conservation importance has been recognized for decades: it was identified in the City’s Conservation Element of the General Plan in 1972 and in the Conejo Canyons Study in 1976 as an area with particularly important and sensitive resources.
Most of the preserve is owned by the Conejo Open Space Conservation Agency (COSCA), which limits access to protect those resources.
What is the natural setting like?
The open space includes steep-sided canyons, oak woodlands, a perennial stream, and riparian vegetation. That vegetation provides habitat for nesting, foraging, and wildlife movement, so the area’s natural features are also a reason to follow access restrictions and stay on designated trails.
Keep in mind that the preserve is not open for unrestricted exploration. A COSCA conservation-plan document describes the rugged, narrow, steep-walled barranca in the upper reaches of the open space as a designated Nature Preserve. Signs at its north and south ends state “Closed to Public Access.”
How do you get to the trail access point?
COSCA identifies trail access from Rancho Conejo Playfield, on the east side of Ventu Park Road just north of Hillcrest Drive. Use that location as your point of reference when planning a visit, and distinguish the open-space trail access from the restricted preserve area.
For context while planning a regional outing, this three-star hotel in Rosemead is in the city.
When can you visit, and what rules apply?
Open space and trails are generally open from sunrise to sunset, but they may close during inclement weather or emergency conditions. Check the official site before you go, as access conditions can change.
On open trails, stay on designated agency-signed routes and leave natural and cultural resources in place. The trail rules also require dogs to remain on a leash no longer than six feet and under control. Bicycles and horses must stay under control and must not endanger visitors, wildlife, or park property.
- Do not pick or collect rocks, plants, animals, or other resources.
- Carry out all trash.
- Motor vehicles are prohibited on trails and in open space.
- Fires, camping, hunting, trapping, and weapons are prohibited; organized events require a permit.
What should you plan for before a visit?
Plan around the access limits first: the trail access point at Rancho Conejo Playfield is not permission to enter the closed barranca. Check the COSCA information for current access conditions, then follow agency-signed trails and the posted rules while you are in the open space.
If you are planning other stops in Rosemead, what to know before visiting Vincent Lugo Park covers a separate local park. Keep the two outings distinct when planning, since the preserve is in Newbury Park.
