Jellyfish Joel's is mostly a boater's playground build on a sandy strip of land at the Great Oak Marina. It is a seasonal location that offers beach food, drinks, live music and a play area for kids of all ages! Drink an orange crush or pain in the [--] cocktail while sunning and wading in the waters of the Chesapeake Bay and nearby creeks. It makes for a fun day in the sun! On holidays in the summer it gets very crowded and you will face long lines to pay $7-8 a drink. A nice excursion.
