The lower gate onto South Park Trail closes on its own but the upper gate needs to be unlatched and relatched when you exit. Please make sure you do that.
Start out at the southern lot on Appleton Road and head out on the Yellow Trail gravel connector. Turn left to stay on the Yellow Trail. Climb up Wayne's World and descend the tricky Disneyland. Your reward is a climb through two open fields. A lot of fun when the hot sun is bearing down on you!
One word: Roots,Roots,Roots! Make a right on the Yellow Trail and take it to the gate to South Park Trail. This trail is pretty much a switchback climb up and a ride back down. Pick up the Yellow Trail off the gravel road and climb back up to the parking lot.
