We have excellent parks and recreational areas in all of Volusia county. The most enjoyable parks, in my opinion, can be found on the Intracoastal Waterway and on the Atlantic Ocean. These have free parking, pavilions, playgrounds, areas for playing frisbee, football or whatever you'd like to do in a wide, open space. And of course, you can always go swimming if you're at one of the ocean front parks.
Don't forget, we're only 30-45 minutes to DeLand also, where they have Ponce DeLeon Springs & Blue Springs, where you can see manatee, rent canoes, swim, play and more.
