When hiking in open space areas, please remember these simple rules:

  • Respect the land as well as the people you encounter along the way.
  • Protect wildlife, plants, and trees. Safeguard streams, ponds, and lakes.
  • Stay to the trails, and keep dogs, horses and bicycles under proper control.
  • Honor the property of others and leave no litter.

Accessibility

Although most of COSCA’s trails are narrow or traverse hilly terrain, the trails below offer broad ease of access:

Oak Creek Canyon Whole Access Trail - adjacent to 482 S. Greenmeadow Ave. is suitable for wheelchair users, families with baby strollers, or those seeking a less strenuous open space experience. This natural-surface trail is approximately ¼ mile long (each way) and passes through a grove of oak trees. A cable handrail and braille interpretive signs are located alongside the trail to aid visually-impaired trail users. Accessible picnic tables and an accessible restroom are available onsite.

Hill Canyon Trail in the Conejo Canyons Open Space - an approximately mile-long trail alongside Conejo Creek in northwestern Thousand Oaks. Although the sideslope and slope of this trail exceed wheelchair accessibility standards by small amounts for short distances in a few places, this gently sloping trail (when accessed from the Hill Canyon trailhead) is suitable for families with strollers or small children and those seeking an easy but scenic hike. The accessible portion ends at a shady picnic table at a trail junction in Hawk Canyon. Accessible restrooms are located at the north end of the equestrian park adjacent to the trailhead.

Mesa Trail in Wildwood Park - offers a barrier-free trail access point adjacent to an accessible drinking fountain and picnic table. Although the sideslope and slope of the Mesa Trail exceed wheelchair accessibility standards by a small margin for a short distance, this gently sloping trail (when accessed from adjacent to the drinking fountain and picnic table) is suitable for families with strollers or small children and those seeking an easy but scenic hike.
