6 places in 4 countries · updated 14 October 2026
In short: By our ranking, the most mystical natural wonders in North America are Great Blue Hole (Belize), Ik Kil (Mexico) and Dean's Blue Hole (The Bahamas). The list covers 6 natural wonders in 4 countries. Mexico has the most, with 3. Last updated 14 October 2026.
Around the Caribbean, limestone tells a story of rising and falling seas. During the ice ages, when sea level was far lower, rainwater dissolved caves and shafts in the exposed rock; when the oceans returned, some flooded into round blue holes and others became the cenotes of the Yucatán, wells of clear fresh water open to the sky. Their depth, stillness and sudden darkness give them a mystery that the Maya understood as an entrance to the underworld.
The Great Blue Hole off Belize is a near-perfect circle of deep blue in the middle of Lighthouse Reef, made famous by Jacques Cousteau. Dean's Blue Hole in the Bahamas plunges beside a beach to one of the greatest depths of any known blue hole and is a centre of free diving. On the Yucatán Peninsula, Ik Kil near Chichén Itzá is an open cenote hung with vines and roots, Cenote X-Keken near Valladolid is a cave lit through a single hole in its roof, and Cenote Angelita hides a layer of hydrogen sulphide that looks like a river flowing along the bottom. In the Texas Hill Country, Jacob's Well is an artesian spring whose narrow opening drops into a long flooded cave.

The Great Blue Hole is a near-perfect circle of deep indigo set in the pale turquoise of Lighthouse Reef, an atoll some 70 kilometres off the coast of Belize. Seen from the air it looks unreal: a ring of coral about 318 metres across, with the water inside dropping away to around 124 metres.
Did you know? A 30-metre sediment core drilled from its floor records 574 storms over 5,700 years, showing tropical cyclones becoming more frequent in recent decades.
Mexico · 35.9 km from Valladolid20.666° N 88.545° W

Ik Kil doesn't look like a cave that happened to fill with water — it looks like the ground simply gave way, which is essentially what happened. The cenote sits open to the sky, a nearly circular shaft about 60 metres across where the water sits some 26 metres below the surrounding ground level and continues down to a depth of roughly 48 metres.
Did you know? In Yucatec Maya the name Ik Kil is usually translated as 'place of the winds'.
The Bahamas23.106° N 75.009° W

On the coast of Long Island in the southern Bahamas, a small crescent of white sand curls around a patch of sea that suddenly turns from pale turquoise to ink. That dark disc is Dean's Blue Hole, a vertical shaft in the limestone that drops to about 202 metres — the third-deepest blue hole known in the world.
Did you know? Only two blue holes are known to be deeper: Taam Ja' in Mexico's Chetumal Bay and the Dragon Hole in the South China Sea.
United States · 24.5 km from San Marcos30.034° N 98.126° W

Jacob's Well looks like nothing more than a round blue pool at the bottom of Cypress Creek — a 12-foot-wide opening in the limestone that people have swum in for generations.
Did you know? In 1924 the spring gushed with such artesian pressure that its water rose about 6 feet into the air above the creek.
Mexico20.137° N 87.578° W

Cenote Angelita — "little angel" — looks unremarkable from the surface: a round pool of dark water in the forest south of Tulum. Its fame lies some thirty metres down. There the diver reaches a thick, milky layer of hydrogen sulphide that hangs across the whole shaft like a cloud or a ground fog, so that it seems to be an underground river flowing through the middle of the water.
Did you know? The sinkhole reaches a total depth of about 60 metres, roughly twice the depth at which the famous cloud appears.
Mexico · 4.6 km from Valladolid20.661° N 88.243° W

X-Keken is a cenote that keeps its secret underground. From the surface there is almost nothing to see: a low entrance in the scrub a few kilometres outside Valladolid, and a flight of steps cut down into the rock. At the bottom the passage opens into a domed limestone chamber holding a round pool of clear, blue-green fresh water, roughly twenty-five metres across.
Did you know? According to Valladolid's tourism office, the cenote was discovered only around 1950, in the middle of the twentieth century.
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
