When the road ends, you have to turn left into the farthest parking lot. Park near the bathrooms at the end of this parking lot. The OPIHI intertidal site is located a 10min walk to the right. Walk along the beach to right. You will walk over a concrete log located perpendicular to the shoreline. The OPIHI intertidal site has man-made concrete cobbles and is located just past a large concrete block located in shallow water.
