Riverside Park Apartment Homes. Located just to the north of Riverside Park is Helmeick Park with a water feature that the kids love to play in and cool off under. Directly behind the property is a bike trail/jogging path that runs for miles both north and south. Across the Arkansas River, west and a little south is the new entertainment complex known as The Riverwalk Crossing, which features fine and casual dining, shopping and a multiplex movie theater. The Tulsa Aquarium is also adjacent to The Riverwalk Crossing.
