It is a tribute to the completion of the first transcontinental railroad in the United States, which occurred on May 10, 1869. The site is home to several interesting points of interest, including the historic railroad grade, a replica of the Jupiter locomotive, and the original ceremony site where the golden spike was driven.

Interesting facts about Golden Spike National Historic Site include that the railroad was built by two competing companies, the Central Pacific and the Union Pacific, who raced to complete the line first. The final spike was made of gold and was driven into a tie to symbolize the completion of the project. The spike was later removed and is now on display at Stanford University.

The best time of year to visit Golden Spike National Historic Site is in the summer months when the site offers daily ranger-led programs and special events, including the reenactment of the golden spike ceremony.
