Editor's Note: Note that the trail is closed between 27th to 35th Streets, including the east end of the Pedestrian Bridge, during construction of Tulsa’s Gathering Place. River Parks’ best-known feature is its recreational trails, most of which have been renovated in recent years thanks to an historic private gift of $12.4 million from the George Kaiser Family Foundation. Adjacent to Riverside Drive, the east bank trails extend from 11th Street near downtown, south to 101st Street. At 96th and Riverside, trail users can leave River Parks and cross the river to Jenks to visit attractions such as Riverwalk Crossing, quaint Main Street shops, and the Oklahoma Aquarium. Traveling east at 96th, trail users leave River Parks and connect to the Creek Turnpike Trail which extends as far as the Broken Arrow campus of Northeastern State University. The Creek Trail crosses major traffic arterials at several locations.At 11th and Riverside, the trail travels north and west to connect to the M.K. & T. Tulsa – Sand Springs Trail near Gilcrease Museum Road. Also known as the Katy Trail, this path connects Tulsa with Sand Springs. The Katy Trail was built on the foundation of an abandoned railroad line and features light grades and long straightaways. River Parks’ maintenance of the Katy Trail ends at Adams Road, a few blocks from Sand Springs’ historic downtown. The trail continues west to Highway 97 and south where it crosses the Arkansas River. On the west bank of the river beginning at 11th Street (Southwest Boulevard), the trail runs south to the Turkey Mountain Urban Wilderness which is bordered on the south by 71st Street.The east bank trails feature separate cycling and pedestrian lanes from 11th to 71st. Renovation of the west bank trails began in 2010 and will occur in phases from I-44, north to 11th Street. When completed, the west bank trails will also feature separate cycling and pedestrian lanes, as delineated by trail markings. All of these asphalt-surfaced trails are open for non-motorized use. The majority of the trails are flat and suitable for a range of fitness levels, with the exception of a steep grade where the trail connects to the Turkey Mountain parking lot, as well as the connection at Gilcrease Museum Road.
