We instead visited the Guana Tolomato Matanzas National Estuarine Research Reserve - that ended being a real delight. It encompasses approximately 73,000 acres along 30 miles of the coast of Florida near St. Augustine. Estuaries serve as nurseries of the sea providing habitat to produce a wide array of marine life. We hiked trails from between the Guana and Tolomato Rivers and the coast (Atlantic Ocean). This place is dog friendly, so Sadie had a great time exploring the area with us.
