If you are coming to the Emerald coast...bring your swimsuit and mittens...ya never know what the weather is like this time of year.
I've been aching to go over to Mystic Springs AS park on the Escambia River... I hear it is beautiful. Also there is a nice small park on the Blackwater River...www.actiononblackwater.com.
They are usually closed during the winter, but, they will open up for you if you call ahead. Carlos and his wife are very friendly.
