University of North Florida Nature Trail. This preserve is over 500 acres and protects the natural flora and fauna of the area. We were able to spot a snake, turtles, and fish. We walked about 2 miles of the trail which included a hike through a swamp with plenty of cedar trees and a lot cooler temperature. Our guide was very knowledgeable and made the trip very interesting for the children using the book "A Home for Ozzie" to help track landmarks.
