The Upper Wildcat Canyon Trail is a continuation of the Wildcat Loop Trail in Rancho San Antonio Open Space Preserve. From the farm, follow the the Wildcat Loop Trail to the left and ascend into the woods for roughly 3/4 of a mile. Here, the Wildcat Loop Trail breaks off to the right while the Upper Wildcat Canyon Trail continues straight ahead. The trail ascends gently through the woods, following the creek which runs on the left side of the trail. As you continue to climb, the creek drops into the valley as the trail climbs along the ridge line. At roughly .7 miles, the trail cuts back and climbs higher along the ridge. Views of the surrounding hills, and the PG & E Trail start to appear on the right hand side of the trail. At 1.3 miles, the trail intersects with the Upper High Meadow Trail
