From hwy 150 in Ojai, go North on Signal St to the National Park sign. You can park on Signal (I prefer this) or you can turn left at the sign and park in the Park parking lot.
Wear layers in the Winter and dress light in the Summer. Bring a your own water and food. Dogs must be on a leash. There are opportunities to cool off in a creek at the beginning of the hike. The last 4 miles or so have no access to water. You see folks walking the 1st 1-2 miles and the last 1-2 miles. The middle part of the hike is usually lightly traveled and gives you some time to yourself.
Did this loop Clockwise, starting at N. Signal Road. My trip was a little different. Northeast corner of original map shown goes through private land, which had gates and No Trespassing signs. We stayed on a fire road/trail (Gridley Canyon, according to bing maps/Hecontage according to google maps) and continued North a bit before turning south toward an overlook over an orange grove. Trail continued along side the groves through some woods and brought us down to Gridley Road.. Turned right on Gridley and walked on the road, facing traffic, for about a third of a mile before getting back on the trail (Shelf Rd/Valley View Rd) just beyond a gate.
Total trip, just over 6.8 miles.
Enjoyed the varied terrain: hiking past a new vineyard, shaded portions on Pratt Trail & down to Gridley Rd, full sun and rolling hills on Fuel Break Trail, but nice view of Lake Casitas to the west. Good view of some of the rock formations to the east that are north of Fillmore by the Sespe Condor Preserve, too. Fragrant orange blossoms along Gridley Road and Valley View!
Elevation ranged from 922' where we parked to 1796' along the Fuel Break Trail, total elevation gain of 1408' over the entire hike. Visited on Apr 06, 2013
