When we think of caves, we imagine how, down the generations, man has lived in many of them and left their footprints. There are many wonderful natural caves, too, which refuse to be deterred by human invasion, and hold such mysteries that are still unrevealed. Let’s look at some of the greatest natural caves in the world.

10. Painted Cave, California

Painted Cave, California

This is no cave with primitive paintings. Why, then, does the cave in the Channel Islands National park in Santa Cruz Island, called so? Because, the walls inside the sea cave are colourful, owing to the rocks, lichens and algae. There are also some wonderfully multi-coloured flowers. Travellers can go kayaking through the cave, and using flashlights, they can be amazed by these cave walls. One of the deepest and longest sea caves in the world, this cave also has an opening that looks like a work of fiction, and a waterfall over this entrance during spring. Altogether, the cave definitely deserves the name.

9. Fingal’s Cave, Scotland

Fingal's Natural Caves

The Fingal’s Cave located in the Staffa Island in the Inner Hebrides is a great wonder for any explorer. It is entirely constructed from jointed basalt columns which are hexagonal in shape. Nowhere else in the world can such a structure be found. The columns provide a crude walkway for the explorers and lead them deeper inside. Formed from gradual the cooling and solidification on the upper and lower surfaces of the solidified lava which led to contraction and fracturing, the unique shape of the walls can be comprehended from outside. The arched roof and the size of the cave, along with the echoes of the waves, create the atmosphere of a cathedral inside this cave overlooking the sea.

8. Caverns of Sonora, Texas

Caverns of Sonora

Dubbed as one of the most beautiful sites in America, it is often said that there is no scope to exaggerate the beauty of the Caverns of Sonora, even for the Texans. This show cave with a natural trail has a stunning array of crystal formations, with helictites found in huge abundance. The helictites show a rare purity and complexity, and are often densely packed, giving the cave an amazing beauty. The most famous formation in the cave, the butterfly, was vandalized by a member of a tour group in 2006, with a large part of its right gone missing. Luckily, the formations are still growing in the cave, and there are chances of its repair.

7. Cave of Swallows, Mexico

The Cave of Swallows is a popular vertical caving destination in Mexico. Formed by the water erosion in a fault in a plain of limestone, it has a conical shape, and the cave walls have holes that provide refuge to white-collared swifts which are relatives of the swallows and hummingbirds, as well as green parakeets. The elliptical mouth opens to the largest known cave shaft in the world. It is a giant hole, large enough to swallow one of the massive skyscrapers in the city of New York, wholly. Extreme sports enthusiasts go to this thickly foliaged cave for free-fall and BASE jumping.

6. Waitomo Glow-worm Caves, New Zealand

The Waitomo Caves in New Zealand are homes to the bioluminescent glow worms that never leave these caves, and glow attract their prey. They also hang gooey, sticky strings of mucous to trap they prey. As one takes a silent ride through one of these heavenly caves, he can see the cave walls studded all over with the glowing dots, which are actually the worms clinging to the walls and ceilings. The threads, too, catch the light and create the most out-of-the-world effect, creating the sight of a starry night inside the cave. It is one of the most sought-after tourist spots in the world, and for good reasons.

5. Antelope Canyon, American Southwest

Antelope Canyon

The Antelope Canyon on Navajo land near Page in Arizona is a slot canyon, formed by the erosion of the Navajo Sandstone. The deep corridors and the smooth edges form a characteristic ‘flowing’ shape in the rock, which have striations of different shades of red, pink, orange, etc. These colours become more vibrant in the Upper Antelope Canyon during the summer months, when the direct sun beams radiate down from the openings in the top of the canyon top. The colours and the beams are more muted in the Lower Antelope Canyon. While tourists are attracted mainly to the vivid monochromatic effects of the Upper Antelope Canyon, photographers frequent both the Upper Canyon, as well as the Lower Canyon with spiral rock arches.

2. Ice Cave near Mutnovsky Volcano, Russia

Natural Caves of  Russia

We all know about the wonder, crystalline ice caves in Austria, Iceland and other parts of the world. But, the ice cave in the Kamchatka Peninsula, near Mutnovsky Volcano, is one of a kind, as it almost brings alive a ‘fire-and-ice’ kind of juxtaposition: it is carved out of a glacier by an underground river which has its source in a hot spring rising from the volcano. Layers of compacted snow build the walls and the ceiling of the cave. Vivid colours and lights can be seen inside the cave, beaming in through the nearly transparent roof and icy windows on the walls. Any light kindled inside the cave is highlighted by the undulations, caused by the eroding warm water.
