Look no further than Marin for a secluded, chocolate-colored sand beach below the highway. Black Sand Beach offers rock outcroppings to block wind on those pesky San Francisco summer days and an uncrowded place to get your feet wet with stunning surroundings.
Be prepared for a short (less than a mile) but steep hike down some stairs to the beach. As with many secluded beaches, Black Sand Beach is popular with nudists. There are often dogs frolicking about here, but the dogs are not technically allowed.
Join the parade of cars winding up twisty Conzelman Road to Hawk Hill, but don’t stop there. Drive a bit farther to the beach parking area on your left, and you’ll see signs for the trail to Black Sands Beach. The 0.75-mile hike down (slightly rickety) steps is sure to put the rosy in your cheeks, and the narrow strip of beach is windy, wild, and stunning.
