"If you want to get a parking spot, either park at the Visitor's Center (North of the Pointe Hilton), or the picnic area off Peoria. The tiny lot at the base of the paved trail fills too fast."
"If you want a great 2 hour hike in the valley, start from either 104th Street Access or Lost Dog Wash-- this is the midpoint. A good 4 hour hike is to go from 104th St to Lost Dog Wash and back, too."
