About the Conejo Valley

ConejoLife covers the communities along the Ventura Freeway between the San Fernando Valley and the top of the Conejo Grade, plus Moorpark and Simi Valley across the hills to the north. The Conejo Valley proper is a basin about 900 feet up, with the Santa Monica Mountains to the south and the Simi Hills to the north. It holds Thousand Oaks and Newbury Park, the city's western half, along with Westlake Village, Agoura Hills and Oak Park. Lake Sherwood and Hidden Valley sit in the mountains to the south. Moorpark and Simi Valley each have a valley of their own, and Highway 23 and the 118 tie them to the Conejo. The Los Angeles–Ventura county line runs through the middle of the region. Agoura Hills and Westlake Village are in Los Angeles County and nearly everything else is in Ventura County, which is why neighbors a few miles apart sign up for different alert systems.

Much of today's map was drawn on old ranch land. Harold and Edwin Janss bought about 10,000 acres of the Conejo in 1910, and their holdings went on to shape central Thousand Oaks. In 1963 Daniel K. Ludwig's American-Hawaiian Steamship Company bought the 12,000-acre Albertson Ranch and planned Westlake. Five cities incorporated between 1964 and 1983. Over the same decades, many ridgelines were set aside instead of built on. Thousand Oaks and its planning area now hold about 15,300 acres of protected open space, and the Conejo Open Space Conservation Agency owns or manages more than 12,700 of them. Those trails connect to national, state and conservancy land in the Santa Monica Mountains and Simi Hills.

Day to day, life here runs through trailheads, Friday-night football, The Oaks, The Lakes and Moorpark's High Street. Simi Valley is home to the Ronald Reagan Presidential Library. Moorpark keeps its farm-town character through Underwood Family Farms, Apricot Lane Farms and the Country Days parade each October. Agoura Hills calls itself the gateway to the Santa Monica Mountains, and the Wallis Annenberg Wildlife Crossing over the 101 at Liberty Canyon is set to open on December 2, 2026.

Residents also know these hills burn. The Woolsey and Hill fires started on November 8, 2018, the day after 12 people were killed at the Borderline Bar and Grill in Thousand Oaks. The Easy Fire in 2019, the Mountain Fire in 2024 and the Sandy Fire in May 2026 have kept evacuation planning part of ordinary life. On the Ventura County side, that means signing up for VC Alert. In Agoura Hills and Westlake Village it means Alert LA County and looking up your Genasys Protect zone. Everyone keeps an eye out for Red Flag days.

What counts as the Conejo Valley?

Strictly speaking, the Conejo Valley is the raised basin in southeastern Ventura County and northwestern Los Angeles County. It includes Thousand Oaks, Westlake Village, Oak Park and Agoura Hills. Newbury Park belongs to Thousand Oaks rather than being a separate town. Broader definitions also take in Lake Sherwood and part of Calabasas, and ConejoLife groups neighboring Hidden Valley with Lake Sherwood. The valley is bounded by the Simi Hills to the north, the Santa Monica Mountains to the south, Conejo Mountain and the Conejo Grade to the west, and the Las Posas Hills and Santa Rosa Valley to the northwest. Santa Rosa Valley is a separate, rural unincorporated valley on that northwest edge. Simi Valley is its own valley between the Simi Hills and the Santa Susana Mountains, and Moorpark lies just west of it along the Arroyo Simi. ConejoLife uses "greater Conejo Valley" for the Conejo proper plus Santa Rosa Valley, Moorpark and Simi Valley. On the Ventura County side, locals often call this territory "East County," because Conejo Mountain splits the county into East and West County.

Two points matter for residents. First, the Westlake master plan crosses the county line. Only the Los Angeles County part became the City of Westlake Village. Thousand Oaks annexed the Ventura County part, about two-thirds of the community, in 1968 and 1972, so a "Westlake Village" mailing address may actually be in Thousand Oaks. Second, Oak Park, Lake Sherwood, Hidden Valley and Santa Rosa Valley are unincorporated communities governed by Ventura County, while canyon communities such as Cornell and Malibou Lake are unincorporated Los Angeles County.

open space agency

Conejo Open Space Conservation Agency (COSCA)

The City of Thousand Oaks and the Conejo Recreation and Park District created COSCA in 1977 under a joint powers agreement. Thousand Oaks and its planning area hold 15,334 acres of protected open space. COSCA owns or manages more than 12,700 of those acres and maintains more than 150 miles of trails. Its list of about 40 named open space areas includes Los Robles, Conejo Canyons, Lang Ranch, Dos Vientos, Mt. Clef Ridge, Rancho Potrero and Lynnmere. A staff of ten rangers patrols the system.

regional park

Wildwood Regional Park

This park covers about 1,765 acres on the west side of Thousand Oaks, in the western Simi Hills. Trails along Arroyo Conejo lead to Paradise Falls, Lizard Rock, Little Cave and the teepee overlook. The park was created in 1967, when the Conejo Recreation and Park District acquired Mount Clef Ridge and Wildwood Canyon from the Janss Investment Company, and COSCA operates it today.

national park unit

Santa Monica Mountains National Recreation Area

Congress authorized this recreation area on November 10, 1978. It is a patchwork of federal, state, local and private land, and its boundary takes in about 153,800 acres across the Santa Monica Mountains and Simi Hills. The National Park Service owns about 23,600 of those acres, and the park headquarters office is in Thousand Oaks. In this region the park's sites include Paramount Ranch, Rancho Sierra Vista/Satwiwa and Cheeseboro/Palo Comado Canyons.

national and state parkland

Rancho Sierra Vista/Satwiwa and Point Mugu State Park

The main entrance is at Lynn Road and Via Goleta in Newbury Park. The Satwiwa Native American Indian Culture Center opens on weekends from 9 a.m. to 4 p.m. The hikers-only Satwiwa Loop Trail crosses land the Chumash consider sacred. The Big Sycamore Canyon Trail follows an old Chumash trade route down into Point Mugu State Park toward the ocean, beneath Boney Mountain. The 2013 Springs Fire burned parts of both parks.

national park site

Cheeseboro and Palo Comado Canyons

These Simi Hills canyons sit on the north side of Agoura Hills, and the main lot is at 5792 Chesebro Road. Hikers, cyclists and riders use the oak-shaded routes to Sulphur Springs and up to Simi Peak.

conservancy preserve

Upper Las Virgenes Canyon Open Space Preserve

The former Ahmanson Ranch covers more than 5,600 acres of the Simi Hills at the western edge of the San Fernando Valley. It protects headwaters of Malibu Creek, and the Mountains Recreation and Conservation Authority manages it. Trailheads are at the west end of Victory Boulevard in West Hills and the north end of Las Virgenes Canyon Road in Calabasas, and trails connect to Cheeseboro Canyon.

Alerts come in English and Spanish by phone, text or email, and TTY/TDD delivery is available. You can register home, work and school addresses, and alerts can be aimed at a single house or two. Besides the online form, you can register by emailing vc.alert@ventura.org or calling 888-772-4482. To replay a missed message, call back the caller-ID number or use the Everbridge app. The county urges residents to sign up even though phones also get Wireless Emergency Alerts. The vcalert.org address redirects to this page.

Ventura County Emergency Information (VC Emergency)

The county's incident dashboard, evacuation updates, recent notifications and Public Safety Power Shutoff updates are all on this site. It has moved from vcemergency.com to emergency.venturacounty.gov. Its FAQ explains that Ventura County draws evacuation zones for each incident instead of publishing fixed neighborhood zones.

Ready Ventura County

The Sheriff's Office of Emergency Services runs this site for planning ahead and building kits. It also explains the Ag Pass program for livestock and crop operators.
