Many U.S. landmarks offer senior-friendly tours or accessibility pathways so visitors can experience the grandeur regardless of physical limitations. More active adults can explore adjacent paths and climb stairs to additional viewing platforms.

If you’re looking to explore a new site or revisit an old favorite, check out these eight U.S. landmarks, starting from the east and heading west toward Phoenix, Arizona.

1. Statue of Liberty and Ellis Island

The Statue of Liberty is one of the most recognizable U.S. landmarks and a worldwide symbol of freedom. On nearby Ellis Island stands a museum dedicated to the millions of immigrants hoping for a new life in America.

Wheelchair-accessible ferries travel regularly between the islands. Seniors’ tickets are discounted for those over the age of 62. The grounds and museums of both islands are paved and walkable. The Statue of Liberty’s observation pedestal requires a climb of 24 stairs, and for those wishing to reach the crown, it’s an additional 192 steps.

New York City bus tours often include Liberty and Ellis Island in their itineraries. Other notable stops are Times Square, the Empire State Building and Rockefeller Center.

2. Washington, D.C.

While there are several notable buildings in Washington, D.C., the Washington Monument stands tallest at 555 feet. The obelisk is a well-known symbol of our capital city. An elevator takes you to a viewing area and museum. Wheelchairs are permitted after passing through security screening.

In addition to the Washington Monument, the capital city has several national museums and memorials. Tourist buildings are required to accommodate people with physical disabilities; however, the surrounding area can demand a lot of walking. Consider touring in electric carts, vintage cars, boats or luxury sedans to help make the day more enjoyable.

3. Niagara Falls

Over 75,000 gallons of water rush over the American and Bridal Veil Falls daily. The Canadian Horseshoe Falls drops another 681,000 gallons. There are a variety of ways for seniors to view falls, gorges and whirlpools, from boats to airplanes and even cable cars. The ADA-compliant Maid of the Mist boat takes viewers to the base of both falls. The Cave of the Winds full tour requires some steps; however, its main viewing platform is wheelchair accessible. You'll need a passport if you wish to leave New York and visit the Canadian side of the falls.

4. Gateway Arch, St. Louis

The city's unique 630-foot arch towers above an exciting riverfront filled with exhibits, gift shops and tasty treats. The park offers several ticket options, which can include the tram ride to the top (not wheelchair-friendly), riverboat cruises and access to exhibits. Brunch and sunset cruises are also available.

5. Mount Rushmore

The idea of creating a sculpture in the Black Hills of South Dakota began in 1923. Sixteen years later, the final figure (Roosevelt) was dedicated. The park includes a viewing area, sculpture studio, museum with videos and walking paths. The entire Mount Rushmore complex is wheelchair-friendly, with elevators, paved walkways and a drop-off area. There are several restrooms and a dining facility in the park.

6. Grand Canyon

Located in northwestern Arizona, the Grand Canyon offers multiple experiences for tourists, from day trips to sunrise and sunset bus tours. Mule rides down into the canyon let you enjoy the stunning scenery without an exhausting trek.

The Grand Canyon Railway makes the trip to the canyon just as exciting with Wild West characters, musicians and, sometimes, a robbery. ADA-compliant train cars have wheelchair lifts and can also store wheelchairs if necessary.

7. Saguaro National Park

Nothing says Arizona more than the Saguaro cactus. While not as tall as man-made monuments or as majestic as waterfalls, it’s an iconic symbol of the American West. Plus, it’s only a 2-hour drive from Bethesda Gardens Phoenix, making it possible to fit in as a day trip.

The park includes loop drives for viewing the incredible scenery from the comfort of an air-conditioned car or bus. Wheelchair-accessible stops and picnic areas provide places to rest. Short paved walking trails are equipped with shaded benches, exhibits and trail guides.

8. Golden Gate Bridge

California’s 1.7-mile Golden Gate Bridge is highly effective, handling millions of vehicles daily, and one of the nation’s most beautiful man-made structures. Seniors can cross the bridge by car or bus or enjoy a water view via a ferry. The ferries have accessible washrooms and can accommodate wheelchairs. Priority seating is also available. Exhibits explain the history of the bridge, and beautiful parks offer trails where you can enjoy the view and indulge in the sport of geocaching.

Traveling in a Group

Touring companies aimed at senior adults offer several advantages, including safety, accessibility, convenience and socialization. When booking with a tour group, consider the schedule, number of people and type of travel. AARP offers lists of senior-friendly tours and ones that accommodate physical disabilities. Always read the reviews of previous tour attendees to see how well the company accomplishes its aims.

Note: The National Park Service sells annual and lifetime Senior passes for use at all national parks and some land management bureaus.
