UNESCO World Heritage Sites: What They Are & Why Travelers Love Them

1209

For those that are new to travel, you may be wondering when reading through an itinerary what is a UNESCO World Heritage Site?

A UNESCO World Heritage Site is a site that holds a list of outstanding cultural or natural universal value such as, the Great Barrier Reef in Australia. It could be a monument, building, mountain, forest, lake, desert, complex or city.

So how is a site selected?

Only countries that have signed the World Heritage Convention, pledging to protect their natural & cultural heritage can submit nominations for properties on their territory to be considered for inclusion in UNESCO’s World Heritage list.

A nominated property is independently evaluated by several Advisory Boards. Once a site has been nominated & evaluated, the intergovernmental World Heritage Committee makes the final decision. One per year, the Committee meets to decide which sites will be inscribed on the World Heritage list.

The program aims to catalogue & preserve sites of outstanding importance, either cultural or natural, to the common heritage of humankind.

There are currently 878 World Heritage Sites in 145 countries. These include 679 cultural, 174 natural and 25 mixed properties.

You may have visited a place in the U.S. already, not realizing it was a UNESCO site such as the Statue of Liberty, Grand Canyon, Yosemite Yellowstone or Olympic National Park.

I have seen 20 sites in 9 countries, so only 858 to go, but I have to say that certain countries do not interest me AT ALL, so my goal would be to see at least half of the UNESCO sites while traveling the world.

How many UNESCO sites have you visited?

Planning Your Next Trip with Atlas Travel Center

At Atlas Travel Center, we’ve spent over 35 years helping travelers turn ideas like the one in this post into fully realized journeys. Whether you’re reading this as inspiration for a trip you’re already planning or as the first seed of a travel dream, our advisors are here to take it from concept to confirmation — handling every detail along the way.

What sets Atlas apart isn’t just our longevity in the business — it’s the depth of expertise we bring to every booking. Our agents are specialists, not generalists. Many have personal experience at the destinations they recommend, onboard the ships they book, and with the tour operators they partner with. When you work with an Atlas advisor, you’re getting counsel grounded in real experience, not just what’s on a website.

Why Work with a Travel Advisor in the Age of Online Booking?

Online booking tools have made it easier than ever to assemble a trip — and also easier than ever to make an expensive mistake. The lowest price on a comparison site often omits a resort fee, books a room category you wouldn’t choose if you saw the photos, or locks you into a cancellation policy that offers no flexibility. Our advisors know the inventory, the fine print, and the suppliers well enough to navigate all of it on your behalf.

More importantly, when something goes wrong — a flight cancels, a ship changes its itinerary, a resort overbooks — a travel advisor is the difference between hours on hold with an 800 number and a quick call to someone who knows exactly who to call. We’ve been solving those problems for clients since 1987, and we’re very good at it.
