Horseback riding and hiking is permitted on roads and designated trails. There are two four-mile-long trails designated for horseback riding. One is located on the Wallula Unit and follows the Walla Walla River on the north side upstream from Madam Dorian Park. The other horse riding trail is located on the Peninsula Unit and follows the river shoreline. Hiking is permitted on the designated horse trails, but hikers must yield to horses. Hikers preferring an upland experience are welcome to explore Juniper Canyon off of State Highway 730/395 in Oregon. There is no maintained trail in the Canyon but plenty of opportunity to explore. Please note that on the McNary Fee Hunt Unit, the public hunt area, is closed to all public entry out of hunting season.
