A new park in Deland offers a 2-mile paved circle trail for biking or hiking. It also provides access to one of the most recent Spring-to-Spring trails. This newly paved trail takes you 2.8 miles to Blue Springs State Park. Once there you can ride another mile in to view the Manatees and other fish and wildlife at the springs. (It'll cost you a buck to get into the State Park with your bike.)
It is off of Fatio Road in DeLand.
