Map of Blackstone River Valley NHP

Explore the Blackstone River Valley with your own Park Passport. Each park site tells the unique story about the Blackstone Valley's important role as a leader in the American Industrial Revolution. The Blackstone Valley was the birthplace of this revolution, and it remains an important reminder of how this pivotal event forever altered U.S. history. The park sites provide an opportunity to learn and enjoy recreational opportunities. Each page in the Passport has a space to stamp or “cancel” the date and location of your visit to each park site.

Passport books can be acquired at any of the park sites, or you can request a Passport book before your visit by contacting us at e-mail us.

After you have collected all the stamps, present your completed Passport to a Park Ranger to celebrate your achievement. The cancellation stamps will be available in at least one spot in each park area. Ask a Park Ranger where the stamp is if you're unsure.
