Small state park, somewhat secluded, very clean and quiet, butt..... if you came for the beach you'll be dissapointed, its small, covered with seagrass and mucky, there's not even a place to wade, however across the street is a bicycle trail, (42 miles long) two miles to the north side of Marathon, I would come again, no wifi and only one Spanish tv station.
Nice, clean, quiet, and in the Keys...what more could you ask for at this price? Gravel, but very clean sites that are private and surrounded by native plants (we are at site 2, which is surrounded by sea grape plants. Bathrooms are currently being renovated, but portables take their place and are kept clean and have ac. VERY short walk to small and sandy beach. Love this place!
