Redding's Sacramento River National Recreation Trail is part of Redding's growing trail system. Meandering over 9 miles along the banks of the beautiful Sacramento River, the wide, paved surface is popular for walking, jogging, roller blading and bicycle riding. Both this trail and the Sacramento Rail Trail have been designated by the United States Department of Interior as Natinoal Recreation trails. Access is available from Hilltop Drive, Caldwell Park, and the beautiful Sundial Bridge.
