From the INCOG Website:
The Jenks Aquarium Trail begins at the Jenks Pedestrian Bridge near 96th & Riverside. The trail serves the Jenks Riverwalk and the Oklahoma Aquarium. The trail continues to an area just west of Elm Street and abruptly ends. The view of the Arkansas River from the bridge is stunning. After crossing the bridge, to the right is the Jenks Riverwalk retail area. To the left (under the bridge) is the Oklahoma Aquarium.
Along the trail, just in front of the Oklahoma Aquarium, there is an Arboretum that has many different trees native to Oklahoma.
