We are fortunate to have such great trails and views of Boney Peak from in Newbury Park. At Wendy and Potrero is the Western edge of the Santa Monica Mountains where Sycamore Canyon cuts through Rancho Sierra Vista/Satwiwa and Point Mugu State Park.
Roughly a mile easy hike from Wendy/Potrero gets you to the Satwiwa Native American Indian Culture Center where you can explore some native Chumash items and educational information and chat with rangers. This is a nice little hike to take the kids on. There are restrooms and water at the center, which is open from 9 to 5 on weekends.
You can get easier access to the center by parking in the adjacent National Park Service parking lot via Lynn Road to the access road at Via Goleta in Newbury Park.
Another mile and a half of hiking gets you to a neat waterfall, which is fun to check out with the kids but somewhat more strenuous of a hike. (Do note that in recent years (2012-2014), the waterfall has barely flowed due to low rainfall.) Here is more information about the Boney Mountain Trail, leading up to Hidden Valley Overlook, the waterfall and Danielson Monument.
