Most travelers have heard of UNESCO World Heritage Sites. Scattered all over the world, they are cultural or natural sites that are considered to be of outstanding value to humanity. Many travelers don’t realize, however, that there are nearly two dozen UNESCO World Heritage Sites in the USA.
World Heritage Sites range from the well known – the Cathedral of Notre-Dame in France, the Historic City of Ayutthaya in Thailand, the Tower of London in England, for example – to such lesser-known places as the Matobo Hills in Zimbabwe, East Rennell in the Solomon Islands and the Struve Geodetic Arc in Moldova. You may not have heard of many of them but they are all exceptional places that need to be protected for future generations.
Today there are more than 1000 designated World Heritage Sites in 161 countries, many of which are of exceptional interest to travelers.
The following is a roundup of the 22 UNESCO World Heritage Sites in the USA that you’ll find closer to home (followed by the date of inclusion on the list).

Grand Canyon National Park (1979)
A powerful and inspiring landscape, the Grand Canyon was carved out by the Colorado River and is the most spectacular gorge in the world.
Its horizontal strata retrace the geological history of the past 2 billion years. There are also prehistoric traces of human adaptation to a particularly harsh environment.
Location: northern Arizona.
Carlsbad Caverns National Park (1995)
Beneath a rugged land of rocky slopes and canyons, cactus, grass, thorny shrubs and the occasional tree, is the hidden treasure of Carlsbad Caverns deep underground. The numerous are outstanding not only for their size but also for the profusion, diversity and beauty of their mineral formations.

Location: on the island of Hawaii.
Kluane / Wrangell-St. Elias / Glacier Bay / Tatshenshini-Alsek (1979)
These parks comprise an impressive complex of glaciers and high peaks on both sides of the border between Canada (the Yukon Territory and British Columbia) and Alaska.
