Everyone that goes to PCB should go to Shell Island. We took the ferry from St Andrews State Park. Keep in mind there isn't any shade, no bathrooms, and no food or water available. You must think ahead and bring whatever you want/need for the day. Walking the beach or snorkelling, you will find tons of shells. If you snorkel, you will be amazed at the clarity of the water. You can see as far underwater as you can above water. There are tons of fish, dolphins, and we even saw 2 small sharks. If I had it to do over, I would have rented a pontoon boat to drive over. That will allow you to hit the beach in a more remote location so you have the beach all to yourself. If you go the way I did and ride over with the people from St Andrews State Park, you will have a nice time as well. We had a great time at Shell Island.
