A great hike

Red and blue and you: If you like hiking through forests thick with redwood trees that level out to panoramic ocean views, and encountering practically no one along the way, then get to Butano State Park and hike the 5-mile (round-trip) Mill Ox Loop on the San Mateo Coast. Soak in views of the long Coastal Range and drop back into the canyon to wander through dense lush ferns. Ahh, solitude. Visit WeekendSherpa.com for details and other local adventures.
