There is a bridge that crosses over the Wilson River as you enter the park. Many people jump off the bridge into the river below. The River is about 15-20 feet below and the water is not clear enough to see through. Therefore, you can never be sure that there isn't something under the surface of the river where you jump. Take extreme caution and jump at your own risk! Just in case, it is good to have someone with you.
