I have dove this site from 1993-2000 many times and 3 more times since I moved away. The coolest part was the WALL OF ABALONE! Either start from the beach and thru the tunnel or walk out past tunnel end & down the steep rock edge. Dive to westside of tunnel entrance and head south around the rock face and you will find a 20ft tall wall some 30-45ft long covered with large abalone about 45ft deep. Lots of bull kelp and a bottom covered in broken shells, and it is best done on a calm day because of the heavy surge.
