Here is one of my favorite places to go...not alot of people know about this place and its a walk to get to the ocean. Once there, many large flat rocks to sit on....no swimming, We love to go and read a book and my husband and grown boys fish off the rocks.

while reading on the rocks you will see many sail boats and fishing boats go by....so pretty and relaxing. We drive 1 1/2 hours to get there and spend the day...we love it..not like the beach with 1000 people in bathing suits just laying around. I just do not see that fun in that.
