Cheyenne-Arapaho Park, or Tsistsistas-Hinono’ei Park (the park’s official name), is a 4.6-acre park located in the Four Square Mile neighborhood of Arapahoe County. The park’s theme honors the Plains Native American tribes, featuring a Cheyenne-Arapaho inspired sculpture and council gathering ring. 

The east side of the park (2.1 acres) was acquired by the County in 1986 and developed for passive use (less structured recreational activities such as walking, picnicking, etc.) in the late 1990s. It has a large turfgrass lawn, circled by a gravel walking path and native plantings. The 2.5-acre west side of the park was acquired in 2006 and minimally improved as an expansion to the existing developed park. 

Through public input and a master planning process completed in 2018, it was determined that the park has been an underutilized recreational resource for this rapidly developing and densely populated area—and had great potential. 

Expansion Construction May 2022-Spring 2023

Construction is underway on west side park improvements as outlined in the 2018 Master Plan, including a new community garden, off-leash dog area, natural play area, extended cottonwood creek bed, and multiple shade and picnic areas. The original character and design inspiration of the park will be honored by preserving the existing Native-American inspired artwork and materials, and by enhancing existing natural vegetation. 

The result will be an improved community gathering place and respite from the surrounding urban area, with more inviting spaces to recreate, relax, picnic, play, garden and socialize. 

Please note: The east side of park will remain open except for periodic closures when needed for construction. Expected project completion is Spring 2023. Many new features are set to open April 7, including a new playground, walking trails, group picnic areas, community garden, and more. A new off-leash dog park at the western end will open later in the spring to give the grass more time to take root prior to heavy summer use. A grand re-opening celebration will be held May 10, 2023, 4-5:30 p.m.
