Access Pass Cost: Free (see note in "how to obtain" for more details) Available for: U.S. citizens or permanent residents with permanent disabilities. Applicants must provide documentation of permanent disability and residency or citizenship. How to obtain: In person at a federal recreation site (see PDF list of federal recreation sites that issue passes) Through the mail using this application form (PDF). NOTE: The cost of obtaining an Access Pass through the mail is $10 for processing the application (the pass is free). This is straight from the nps.gov website.
I am not aware of any disability passes. Contact the battlefield directly.
