Denison University Biological Reserve is 350 acres of land to enhance the education of students in biology and environmental sciences through their courses. The reserve provides refuge for numerous amphibians, turtles, snakes, rodents, flying squirrels, deer, red fox and over one hundred species of birds. The trail doesn't have any real technical spots, just sharp turns and some short climbs. The trails are well maintained with great opportunities to see wildlife and birds.
