Hundreds of thousands of years in the making, each underground cave is completely unique. Formed by water erosion, with the occasional help from some strong winds, it’s no wonder sea caves are a huge tourist draw for those who love Mother Nature’s spectacles. Just like these 13 breathtaking photos of cliffside cities and towns, you’ll be blown away by each of these incredible sea caves.

An excellent diving site, tourists and locals alike love visiting this incredible set of caves. The two caves known as Cenote Dos Ojos were created by two 21.33-metre sinkholes that were connected by a narrow underwater passageway. If you take one of the local guided tours or enter to scuba on your own, you’ll see lots of underwater fish and two types of shrimp. Rather stay at the water’s surface? There you can enjoy the bat cave!

Playa de las Catedrales, or the beach of the cathedrals, is located off the Cantabric Sea coast. To keep humans’ effect on these caves to a minimum, there is a limited number of people allowed into this attraction every day. You can make a reservation online ahead of time to ensure you and your travel companions will be able to get in. The arches and caves that make this place famous are only accessible during low tide which occurs twice a day.

Yes, Wisconsin is nowhere near any saltwater so calling this a sea cave might be a bit of a stretch, but this hidden gem is too incredible to skip. Located just off Lake Superior, summer visitors to these incredible water-filled caves will catch a glimpse of the stunning red sandstone that makes up the rock formations in this area. The best experience can be had in the winter when the freezing and melting of the water creates millions of icicles that sparkle like diamonds on the walls and ceiling of the caves.

Located on the island of Sardinia, Italy, this cave contains both major forms of mineral deposits, but it is well known for its stalactites. (Stalactites are the mineral deposits that grow down from the ceiling, like icicles, whereas stalagmites grow up from the floor.) Neptune’s Grotto is estimated to be about two million years old and has become a very popular tourist site. While the full extent of this sea cave is massive, only a few hundred metres are open to the public.

This area has been a privately-owned wildlife preserve since 1932. In the winter, the local sea lions take refuge from the weather by retreating into the sea caves, but in the summer, you’re more likely to find them on the rocky shoreline. These caves are estimated to be 25 million years old and today, it is the length of a football field, and nearly 12 storeys high. Travelling with someone who needs easier accessibility? This sea cave has elevator access!

One of the world’s deepest sea caves, you can paddle a kayak straight in – in the springtime you’ll have to paddle through a light waterfall that trickles over the entrance. There are plenty of tour companies that offer guided tours. The name comes from the unique coloured rocks and lichen that appear on this massive cave’s walls.

Calling this a sea cave is slightly misleading. Playa Escondida used to be a sea cave, but long ago, the cave’s ceiling collapsed and it is now better described as a hidden beach. Often referred to as the “eye to the sky,” this former sea cave is now a hugely popular swimming and sunbathing spot.
