Except for the most modern and upscale hotels in major cities, most buildings in South America are not well equipped for travelers with disabilities. Where elevators exist, they are often tiny. Many cities in South American streets are crowded and narrow. In the Andes, the high altitude and steep hills slow everyone down.
Nevertheless, a disability shouldn't stop anyone from traveling. There are more resources out there than ever before. Some of the best include MossRehab (www.mossresourcenet.org), which provides a library of accessible-travel resources online; the Society for Accessible Travel and Hospitality (SATH; tel. 212/447-7284; www.sath.org; annual membership fees: $45 adults, $30 seniors and students), which offers a wealth of travel resources for all types of disabilities and informed recommendations on destinations, access guides, travel agents, tour operators, vehicle rentals, and companion services; and the American Foundation for the Blind (tel. 800/232-5463; www.afb.org), which offers a referral resource for the blind or visually impaired that includes information on traveling with Seeing Eye dogs.
Also check out the quarterly magazine Emerging Horizons ($15 per year, $20 outside the U.S.; www.emerginghorizons.com); Twin Peaks Press (tel. 360/694-2462), offering travel-related books for travelers with special needs; and Open World Magazine, published by SATH (see above; subscription: $13 per year, $21 outside the U.S.).
Many travel agencies offer customized tours and itineraries for travelers with disabilities. Flying Wheels Travel (tel. 507/451-5005; www.flyingwheelstravel.com) offers escorted tours and cruises that emphasize sports and private tours in minivans with lifts. Accessible Journeys (tel. 800/846-4537 or 610/521-0339; www.disabilitytravel.com) caters specifically to slow walkers and wheelchair travelers and their families and friends.
