San Bruno Mountain is Northern-most section of the Santa Cruz range and the last stronghold against urban sprawl. It has a very recognizable 1,314-foot summit, steep ravines and deep valleys that provide refuge for a variety of plants and animals. San Bruno Mountain State Park has 2,378 acres with numerous trails of all difficulties and easy access to the city. This is an ideal outdoor getaway for someone traveling to San Francisco with limited time, as the trailhead is less than 15 minutes from the city or the airport! If you're still unsure which mountain I'm referring to, it's the one near the big white letters on the hillside reading "South San Francisco The Industrial City." That's the one. The fog can often limit the view, when it's clear expect an incredible 360 panorama of the Pacific Ocean and bay area!
