In 2012, the Conejo Canyons bridge was constructed in Thousand Oaks, opening up more trails to explore in the Western Plateau area of Thousand Oaks, which ties into Wildwood Park. Check the map at www.cosf.org/website/html/western-plateau-hikes.html for trail maps.
Access the Conejo Canyons bridge to get to the Hill Canyon Trail, a flat path that after a mile takes you to an intersection where you can go straight ahead to the Hawk Canyon Trail, take a right turn to the Western Plateau Trail or veer left to make your way to the Arroyo Conejo Trail that takes you about 2 1/2 miles to the Rancho Conejo Playfields in Newbury Park.
One path I enjoy is the Hill Canyon Trail to the Hawk Canyon Trail, which veers right towards the Western Plateau Trail, which loops back to Hill Canyon Trail. Do look at a map first as signs are not always at trail junctures (the sign above is clearly an exception!). You can actually take the Hawk Canyon Trail as well as Western Plateau Trail to Newbury Park.
Access the Conejo Canyons bridge via Santa Rosa Road. Coming from Thousand Oaks, take Moorpark Road north down the Norwegian Grade, where it intersects with Santa Rosa Road. Continue about 3.7 miles on Santa Rosa Road and make a left on Hill Canyon Road. Drive down Hill Canyon Road and you will see a large, flat dirt parking area on the right, adjacent to Santa Rosa Valley Regional Park.
