Yosemite publishes an accessibility brochure (www.nps.gov/yose/planyourvisit/upload/access.pdf) and Sequoia and Kings Canyon have an online link with helpful information (www.nps.gov/seki/planyourvisit/accessibility.htm). Both are excellent sources of information on everything from hotels and campgrounds to visitor sites and ranger-led activities. If you need to make arrangements in advance, call any park visitor center or contact the accessibility coordinator prior to your arrival.
Most sights and campgrounds within the parks are wheelchair accessible; for a complete and detailed list, download the accessibility brochure. All Yosemite campgrounds have accessible sites, except for Camp 4, Bridalveil Creek and Hodgdon Meadow.
All lodging options within Yosemite have wheelchair-accessible rooms.
For hearing-impaired visitors, a ranger may be available during the summer months for American Sign Language (ASL) interpretation during park-led walks and talks. For information contact one of the visitor centers or call 209-372-4726 (TTY). For paid tours, ASL interpretation can be arranged through the Yosemite Valley Lodge tour desk.
Based in Mammoth Lakes the nonprofit organization Disabled Sports Eastern Sierra offers a variety of educational opportunities for travelers with disabilities, including skiing and climbing courses.
Discount passes to the parks and national forests are available for people with disabilities.
