When it comes to planning a vacation, there's no shortage of places to visit. Some spots offer beautiful beaches and relaxation, while others have no shortage of landmarks and other historical sites to take in. For any seniors interested in taking a trip, here's a short list of a few places on the map that are particularly exciting.

5. Niagara Falls
As Insider Monkey pointed out, Niagara Falls is really a great vacation spot for people of all ages, and has accommodations for couples, families or even the lone visitor. In Canada, Niagara Falls is a quaint city that sits on the Western side of the massive waterfall. Just a short drive away over the Rainbow Bridge, seniors can head into the United States to see a different angle of the falls, as well as visit Buffalo, New York and other American cities. Hop on the Maid in the Mist - a boat that takes you right up to the falls and get up close and personal with this amazing feat of nature.

According to the Niagara Falls State Park website, 3,160 tons of water flow over the site every second, accounting for the landmark's impressive stature. In fact, water from four of the five Great Lakes flows through the Niagara River and into Lake Ontario on the other side of the falls. Collectively, these lakes make up almost 20 percent of the world's fresh water. 

4. San Francisco 
One of the most cultural cities the U.S. has to offer, San Francisco has no shortage of places to see, as well as a rich culinary landscape. Sites like the Golden Gate Bridge and Lombard Street are famous the world over, and certainly worth a visit.

Elsewhere in San Francisco, seniors can grab a bite to eat at Pier 39. Located on the city's beautiful waterfront, there are many options for catching live music or eating some fantastic seafood, all set to the scenery of San Francisco Bay. Sea Lions are frequent visitors to this area of the city, while just a 30 minute ferry ride off shore sits Alcatraz, the old prison island. 

3. Quebec City
One of Canada's most enchanting places to visit, Quebec City has a rich history and modern flair. During the winter, snow-capped buildings and the icy St. Lawrence River make the city a sight to behold, while warmer summer weather allow visitors an opportunity to stroll old Quebec and visit other historic sites, Trip Advisor reported

The Aquarium du Quebec is just one of many family-friendly places to visit in the city, along with many parks and museums. Although it is located right here in Canada, the French influence makes it feel as if you are exploring an old European city like Paris or Rome more than a Canadian location like Ottawa or Vancouver.

2. The Bahamas
For seniors looking to take in some fun in the sun, the Bahamas are a fantastic choice because there are so many options for where to stay. There are hundreds of individual islands and dozens of accommodations, from famous resorts like the Atlantis to private bungalows or villas. 

Located just off the coast of Florida, the Bahamas are perfect for a trip in the spring or early summer because the weather hasn't gotten too warm, but really these islands are great year-round.

1. Yellowstone National Park
There are many different wild areas in Canada to see plants and animals, but Yellowstone National Park is one of the best places to take in the natural beauty of North America. The oldest National Park in the U.S., there are also historic points of interest, on top of the opportunity to see a pack of wolves or a herd of bison.
