Mohawk Park, containing 3,300 acres, is the largest park in Tulsa and one of the largest city parks in the country. The sprawling park was created as part of the 1924 public works project that piped drinking water from the Spavinaw Dam to Tulsa. More than 800 acres of the park feature Oxley Nature Center with hiking, picnicking, a 5-acre marsh with 600 foot boardwalk and observation tower and 9+ miles trails. The interpretive center houses hands-on exhibits, an observation beehive, restrooms and drinking water. The area is also home to abundant wildlife and waterfowl, the Tulsa Zoo and the Mohawk Park Golf Course, 36 hole disc golf course, several CCC-era picnic shelters, polo field and several miles of equestrian trails.
