#6 in Natural Wonders
of 16 ranked entries
Ecuador · volcanic archipelago
The isolated wildlife Charles Darwin observed here in 1835 directly shaped his theory of evolution by natural selection, and the islands remain one of the tightest-regulated ecosystems on Earth, with a strict cap on resident population growth and mandatory certified guides for most visitor sites. Recorded specifics: country Ecuador, area (km²) 7995, type Island & marine. Panel highlighted directly shaped Darwin’s theory of evolution, giving the islands a unique place in the history of science, among the most strictly regulated tourism environments on Earth, with hard caps on visitor sites and boat numbers and endemic species found nowhere else on the planet remain remarkably unafraid of human visitors. The reservation on record is invasive species introduced via tourism and settlement remain an active, difficult-to-reverse threat to native wildlife and warming ocean currents linked to El Niño cycles have caused repeated die-offs among marine iguanas and seabirds.
Score breakdown
Each criterion is scored independently, then combined using the weights published on Natural Wonders.
“The Galápagos was the first site ever inscribed on UNESCO’s original 1978 World Heritage list, alongside just eleven other locations worldwide.”

From the same list
Arizona, USA · carved over roughly 6 million years
The Colorado River cut roughly 1,800 metres deep into layered rock that exposes close to two billion years of Earth’s geological history in a single cliff face, making it one of the most complete geological timelines visible anywhere on the planet’s surface.
Queensland, Australia · largest living structure on Earth
Built by billions of individual coral polyps over roughly 20,000 years, it is large enough to be visible from space and supports thousands of marine species, but it has suffered five mass bleaching events since 2016 alone as ocean temperatures have risen.
South America, spanning nine countries
Produces an estimated 20% of the world’s river discharge and is often described as the planet’s lungs, though it is more accurately a carbon sink than a net oxygen producer at this point — parts of the eastern Amazon have already begun emitting more carbon than they absorb due to deforestation.
Nepal / Tibet border · 8,849 metres
The highest point on Earth above sea level draws hundreds of paying climbers each spring season, and the resulting queues near the summit on clear-weather days have become as much a symbol of the mountain as its scale — over 300 people have died attempting the climb since records began.
Zambia / Zimbabwe border · Zambezi River
Known locally as Mosi-oa-Tunya, "the smoke that thunders", it is classified as the largest single sheet of falling water in the world by combined width and height rather than by either measure alone, and its spray is visible from over 20 kilometres away during peak flow.
Argentina / Brazil border · Iguazu River
A system of 275 individual waterfalls spread across nearly 3 kilometres, roughly twice the width of Niagara Falls, with the horseshoe-shaped Devil’s Throat cataract alone dropping 82 metres and producing a spray cloud visible for kilometres.
Antarctica · governed under the Antarctic Treaty, 1959
The most accessible and fastest-warming part of the continent, visited by an estimated 100,000-plus tourists a year via expedition cruise, a number that has grown so quickly that Antarctic Treaty parties have repeatedly debated formal visitor limits that do not yet fully exist.
Potosí, Bolivia · world’s largest salt flat
A prehistoric lake bed left behind roughly 10,582 square kilometres of salt crust so flat that satellite altimeters use it to calibrate their instruments, and a thin layer of rainwater across the surface each wet season turns it into the world’s largest natural mirror.
