Certified sites are sites that have undergone the National Trails office certification process. This process allows the owners and managers of places related to the national historic trails to become certified partners of the National Park Service. Each national historic trail administered by the office maintains a list of its certified sites. To view the lists, just click on the links on the right side of this webpage.
If we have left out your certified site or if the information listed for your site is not correct, please email us with the changes that should be made.
