Designated as Idaho’s Western Historic Byway, enjoy a relaxing ride through the Western Snake River Plain and Morley Nelson Snake River Birds of Prey National Conservation Area to Celebration Park. Established in 1989, it is Idaho’s only archaeological park.  Stroll along several pathways to see the incredible basalt petroglyphs, some which date more than 12,000 years ago

​

At the western end of the park, is Idaho’s largest historic artifact, the Guffey Railroad Bridge, built in 1897 to carry gold and silver ore from Silver City in the Owyhee Mountains to Nampa for smelting. The bridge is the only Parker-Through-Truss railroad bridge in Idaho. The 450-ton steel structure is 70 feet tall and spans 500 feet over the Snake River.
