Whiting Ranch 20k

Begin on Serrano Road anywhere south of Portola, where parking is convenient, and take the trail under Portola Pkwy;then hike through the entry gate. Continue up the main trail, Serrano Road, and skip the two side trails Raptor Road and Live Oak Trail. At the next fork, stay right on Serrano Cow Trail and continue the gradual climb. Pass by the turn to Line Shack Trail, and continue until the left turn onto Whiting Road. Grit your teeth and climb to "Four Corners", where three other trails will connect. Two of these trails climb higher, and you'll pick the one that goes back down, Mustard Road. Before descending, grab some water from the fountain next to the kiosk (keep your fingers crossed that it is flowing, sometimes it's not).Relax now and enjoy the easy hike down. Ignore any side trails as Mustard Road flows into Borrego Canyon Trail and ends at the Portola parking and trailhead. Get more water at a fountain here, or stop by Ralphs next door and pick up a more refreshing treat. After recharging, head back up Borrego Canyon Trail and follow signs to stay on Mustard Road. A short distance up Mustard Road, just a couple switchbacks after passing the left-turn onto Red Rock Canyon Trail, take the next left turn and head up Billy Goat Trail. This is a great narrow singletrack with quick switchbacks, and steep ups and downs. This is a hiker-only trail, so don't worry about bikers or horses. At the top, pick your lungs up off the ground, and turn right onto Whiting Spur Road.Keep right of the water reservoir to drop back into 4 Corners and break for water if needed. Head back down the way you first came up, but hang left to go down Cactus Hill Trail. This is a fast and fun downhill that continues for quite a ways. Take the next two right turns to end up on Sleepy Hollow Trail, and follow this back down into Whiting Road (enjoy the switchbacks and beautiful hike through the trees!) At the end of Whiting Road, you'll ignore the trail angling back up to your right, and take the next right back onto Serrano Cow Trail. Just past the left turn onto Line Shack Trail, take the left fork onto Live Oak Trail and enjoy a fun and winding singletrack through the trees. When this trail ends, turn right onto Raptor Road and take it back around to Serrano Road. Turn left onto Serrano Road and continue back out of the park and to your starting point.
