South side of the inlet in the park area for the normal cucumers, shrimp, snails, crabs, small fish. The niice thing is you can pay one fee at either side of the park and gain entry to both sides. The north side just off shore I have been told is good for snorkeling. Watch the rips as they have been pretty rough on the ocean side as I have been seeing on the news.
Water may be a bit chilly as well. Map quest search for Sebastian Inlet National Park for directions...webasso bridge or there is another I cannot remember. Maybe skinnyjoe remembers....LOL
Hope this helps
