The 21-acre Knoll Open Space is located next to Pepper Tree Playfield in Newbury Park. This area, which is owned by COSCA, is covered in a mosaic of non-native grasslands and coastal sage scrub. A gently sloping trail leads to the top of the hill, which offers views of Newbury Park and the surrounding area.
