We’ll hike briskly 4 miles south on Limantour Beach to reach Sculptured Beach before the tide changes. We’ll continue south to the less accessible portions of Sculptured Beach by climbing down a 6-foot rock outcropping. We’ll explore along tide pools, archways, and caves down the final section of beach to the “Thumb” sea stack. We will either turn around at the end of the beach or, if the tide still allows, pass through a walking passage keyhole to “Super Secret Beach” and its entrance to the bottom of a sheer-walled 100 ft deep collapse sinkhole. We’ll then retrace our steps to Sculpture Beach, followed by a leisurely hike back along Limantour Beach to the parking lot. Wear footwear that can get wet. Extra dry socks and a headlamp recommended.
