Nature's frosted wonders: 7 Stunning icy caves from around the world

These are really cool (literally)

Found in cold regions or near glaciers, these caves are made entirely of ice and exploring them is an experience of its own.  From the glowing blue tunnels in Iceland to the frozen chambers in Alaska, each ice cave is unique and constantly changing with the seasons. They’re nature’s hidden gems, offering a glimpse into a world that feels like it’s straight out of a fairytale. Here are the most beautiful icy caves around the world.

Apostle Islands Ice Cave – USA

Located on Lake Superior's shores, the Apostle Islands Ice Caves are a winter marvel. During the cold months, when Lake Superior freezes, the cliffs along the Apostle Islands transform into a stunning ice spectacle. The caves feature dramatic ice formations, including towering columns, frozen waterfalls, and intricate ice sculptures. The best time to visit is from January to March when the ice is at its most spectacular. The icy trail to the caves also offers breathtaking views of the frozen lake.

Crystal Ice Cave – Iceland

The Crystal Ice Cave, also known as the Breiðamerkurjökull Ice Cave, is known for its super clear, glass-like ice. The cave’s smooth walls and stunning blue tones make it feel like you’re standing inside a giant gemstone. Because of its transparency and beauty, it’s one of Iceland's most photographed ice caves.

Eisriesenwelt Ice Cave – Austria

Tucked in the Alps near Salzburg, Eisriesenwelt is the largest ice cave in the world, stretching over 26 miles! Only the first mile is open to visitors, but it’s packed with jaw-dropping frozen waterfalls, giant icicles, and massive ice formations. Fun fact: “Eisriesenwelt” means “World of the Ice Giants,” and once you’re inside, you’ll see why—it’s like entering a frozen kingdom!

Vatnajökull Ice Caves – Iceland

The ice caves in Vatnajökull, Iceland’s largest glacier, are famous for their glowing blue ice. This dazzling blue color happens because the ice is so dense it absorbs all colors of light except blue. Every year, as the glacier shifts, new caves form, making each visit unique.

Mendenhall Ice Caves – Alaska, USA

Located under the Mendenhall Glacier near Juneau, these surreal ice caves feel like you're walking inside a glowing blue bubble. The caves constantly change as the glacier melts, so no two visits are ever the same. Reaching them can be tricky, but the payoff—being surrounded by shimmering blue ice—is unforgettable!

Mer de Glace Ice Cave – France

Mer de Glace, or “Sea of Ice,” in the French Alps, is the largest glacier in France. Every year, a new ice cave is carved into the glacier, complete with ice sculptures and tunnels. The cave's twinkling ice walls make it feel like you’ve stepped into a frozen fairy tale. Plus, getting there involves a scenic train ride through the stunning Alps!

Big Four Ice Caves – USA

Found at the base of Big Four Mountain in Washington State, these caves are shaped by melting snow and ice. They change size and shape with the seasons, so each visit offers a different icy experience. Just a note: because the caves can be unstable, it’s best to enjoy their beauty from a safe distance.

Rhône Glacier Ice Grotto – Switzerland

Every year, a new ice grotto is carved into the Rhône Glacier in the Swiss Alps. Inside, you'll be surrounded by crystal-clear ice, which creates a peaceful, otherworldly atmosphere. The Rhône Glacier itself is shrinking, but the grotto continues to be an awe-inspiring way to experience the heart of a glacier up close.

Scărișoara Ice Cave – Romania

This cave in Romania’s Apuseni Mountains houses a massive block of ice that’s over 3,000 years old! The Scărișoara Ice Cave is one of the largest underground ice caves in Europe, and the ice never melts, even in the summer. It feels like a journey back to the Ice Age, with ancient frozen formations greeting you at every turn.
