Most disabilities shouldn't stop anyone from traveling in the U.S. Thanks to provisions in the Americans with Disabilities Act, most public places are required to comply with disability-friendly regulations. Almost all public establishments (including hotels, restaurants, and museums, but not including certain National Historic Landmarks) and at least some modes of public transportation provide accessible entrances and other facilities for those with disabilities.
The America the Beautiful -- National Park and Federal Recreational Lands Pass -- Access Pass (formerly the Golden Access Passport) gives the visually impaired or persons with permanent disabilities (regardless of age) free lifetime entrance to federal recreation sites administered by the National Park Service, including the Fish and Wildlife Service, the Forest Service, the Bureau of Land Management, and the Bureau of Reclamation. This may include national parks, monuments, historic sites, recreation areas, and national wildlife refuges.
