Fingal’s Cave—Isle of Staffa, Scotland
At 72 feet tall and 270 feet deep, this cave is unlike any other. Fingal’s Cave on the uninhabited Isle of Staffa in Scotland is formed entirely of hexagon-shaped basalt columns. Its unique design has had an influence on a fair share of its visitors, including Pink Floyd. (Pink Floyd actually named an early, unreleased song after the cave.) To visit this incredible structure, you can take a boat or hike from the island. However you get there, you’ll be glad you checked this cave off your bucket list. Speaking of bucket lists, you NEED to add these 15 homes built in really strange places to yours.
Ana Kakenga—Easter Island, Chile

Ana Kakenga is the most visited cave on Easter Island—and for good reason. To visit the cave, you must enter through a small hole in the ground, which measures to be slightly less than two feet wide. As you could imagine, the entrance is very tough to find without a tour guide. After you enter the 164-foot-long volcanic tube, you’ll find two stunning naturally formed windows looking over the water.
