Stunning sinkholes around the world

Sometimes, what looks like solid ground suddenly collapses to create some of the world's most spectacular natural sights: sinkholes, blue holes and cenotes. They can be found around the globe.

Great Blue Hole | Belize

The 1,043-foot-wide hole came to be after an above-ground cave collapsed some 15,000 years ago. Today, it's a UNESCO World Heritage site and a great spot for beginner divers.

Blue Holes | Palau

Blue Holes is a large, deep cavern beloved by adventurous divers. There are four holes in the reef that enter the cavern, which is home to wire corals, sea fans and leopard sharks.

Ik Kil | Yucatan, Mexico

Vines drape from the ledge of the 200-foot-wide opening above, and a staircase leads visitors down to the edge of the water of the famously beautiful Ik Kil cenote.

Darvaza Crater | Turkmenistan

Known as the 'door to Hell,' this crater isn't a natural sinkhole. It was lit on fire after drilling and collapse lead to methane gas leaking. It's been burning ever since.

Bimmah Sinkhole | Oman

This is considered one of the most beautiful sinkholes on the planet, and it serves as a swimming hole for local residents and tourists who come to see its azure waters.

Dean's Blue Hole | The Bahamas

This is the world's second deepest known saltwater sinkhole, plunging 663 feet into the bay off Long Island. It's also the site of many freediving stunts.

Montezuma Well | Arizona

Montezuma Well was formed by the collapse of a limestone cave. Today, more than a million gallons of water flow through the sinkhole each day.

Blue Hole of Dahab | Egypt

Known as an 'underwater cathedral,' this sinkhole is 394 feet deep and is lined by gorgeous coral. It's infamous for being dangerously deep and disorienting.

Nanda Blue Hole | Vanuatu

Appearing as a perfect, secluded lagoon oasis in the jungle, this blue hole is reachable via a 2-hour paddle up a tidal river during an incoming high tide.
