The Jacksonville Arboretum & Gardens is a 120-acre urban woodland full of trails for you to explore and enjoy.  From the trailhead next to the parking lot, a stabilized walkway encircles a beautiful two-acre lake. This trail gently descends about 25 feet to the foot of the lake and then returns up a gentle slope on the opposite side to the trailhead. Interpretive signs and over 100 labeled plants enhance the loop. In addition, over three miles of rustic hiking trails wind quietly through a series of distinct ecological habitats.
