Celebration Park, Archaeological site along Snake River in Idaho, United States.

Celebration Park is an archaeological site along the Snake River where visitors can see ancient petroglyphs carved into basalt rocks. The rock formations were shaped by the massive Bonneville flood that occurred thousands of years ago and created the landscape visitors see today.

Celebration Park lies within the Guffey Butte–Black Butte Archeological District, listed on the National Register of Historic Places. Its petroglyphs, carved by Native Americans, include some dating back more than 12,000 years. The park's Guffey railroad bridge was built in 1897 to carry gold and silver ore from Silver City to Nampa; abandoned in 1947, it was saved from demolition in the 1970s and purchased and restored by Canyon County in 1989.

The location served as a seasonal residence for Native American groups including Paiute, Shoshone, and Bannock people who used the land for sustenance.

The park provides picnic areas, restrooms, and drinking water at various spots for visitors to use while exploring. Guided tours are available to help visitors understand the petroglyphs and the site's archaeological importance.

The Guffey railroad bridge, built in 1897, is the only Parker through-truss railroad bridge in Idaho and the state's largest historic artifact. Its 450-ton steel structure stands 70 feet tall and spans 500 feet over the Snake River; it was listed on the National Register of Historic Places in 1978.
