Along Highway 101 a side road leads to parking areas at Clam Beach. You walk along sandy hills to get to the wide sandy beach. Miles of beach head stretches northward towards the rocky cliffs below the town of Tinidad, California; and miles and miles of sandy beach stretches out to the south. Be prepared for winds at this beach. The surf was robust the day I was there. A couple of miles south along Highway 101 is the turn off for Mckinleyville, and then a few more miles to the south until you reach the large turnoff complex at 299 and 101.
