There’s something about volcanic craters that stirs the imagination. Maybe it’s their raw, untamed beauty or the fact that they’re a powerful reminder of Earth’s fiery beginnings. Whatever the case, these dramatic landscapes often look like they were plucked straight out of a sci-fi movie. From towering rims and vibrant mineral pools to ash-covered moonscapes, volcanic craters offer some of the most surreal travel experiences imaginable. If you’re ready to explore places that feel like another planet, grab your sense of adventure and follow me to some of the most mind-blowing volcanic craters around the globe.
1. Crater Lake, Oregon, USA
Stepping onto the rim of Crater Lake feels like peering into a world untouched by time. This vast, sapphire-blue lake fills the caldera of a long-dormant volcano called Mount Mazama. Formed nearly 7,700 years ago, Crater Lake is the deepest in the United States, and its pristine waters are so clear they mirror the sky above.
Take a hike along the rim for breathtaking panoramic views, or head down the Cleetwood Cove Trail to dip your toes in the icy water. If you’re feeling adventurous, hop on a boat tour to Wizard Island, a volcanic cinder cone that rises from the lake. The silence here is almost otherworldly, broken only by the sound of wind rustling through the pines.
2. Mount Bromo, East Java, Indonesia
Picture this: The sun rises, casting an orange glow over a dusty, ash-gray landscape dotted with volcanic peaks and mist-shrouded valleys. This is Mount Bromo, and it’s a scene straight out of another world. Part of the Tengger massif, this active volcano is famed for its surreal beauty and easy accessibility.
The best way to experience Mount Bromo is by jeep or on horseback. The Sea of Sand (yes, that’s its actual name!) stretches out like a barren, alien desert, leading up to the crater rim. Peer inside, and you’ll see steam rising from the smoldering depths below. For the ultimate experience, watch the sunrise over the mountain from nearby Mount Penanjakan. The view will leave you in awe.
3. Ngorongoro Crater, Tanzania
Technically a caldera, the Ngorongoro Crater in Tanzania is a lush oasis surrounded by volcanic rock walls. But here’s the fun twist—this crater isn’t just a geological marvel; it’s also a wildlife wonderland. Picture an artist’s palette of greens, golds, and browns, with zebras grazing in the grasslands and flamingos dotting the saltwater lakes.
Take a safari tour into the heart of the crater and get up close with lions, elephants, and rhinos. The air is alive with the sounds of nature, from birds chirping to the distant roar of a lion. When you stop to take it all in, it’s easy to feel like you’ve stepped into an ancient, otherworldly paradise.
4. Kelimutu Crater Lakes, Flores Island, Indonesia
Kelimutu is proof that nature is the greatest artist. This stunning volcano on Flores Island is home to three crater lakes, each a different, vibrant color. Yes, you read that right. Depending on the volcanic gases and minerals in the water, these lakes can change from turquoise to emerald to a haunting shade of red or black.
Hike up the well-marked trail to the top of Kelimutu to catch the sunrise over this surreal scene. Watching the shifting hues of the lakes as the sunlight dances across their surfaces feels like witnessing magic. Bonus? The trek offers views of lush hills, narrow villages, and coffee plantations below.
5. Mount Etna, Sicily, Italy
Mount Etna isn’t just Europe’s highest active volcano; it’s also one of the most mesmerizing. With its smoldering craters, black lava fields, and striking contrast against Sicily’s blue skies, Etna feels like the kind of place astronauts should train before heading to Mars.
You can ride a cable car partway up the mountain and then join a guided hike to explore its craters up close. As you trek across the eerie, blackened landscape, expect to feel the crunch of volcanic rocks underfoot. And if luck is on your side, you might even catch a glimpse of molten lava during an eruption. Just imagine the warm sulfuric steam hitting your face as you stand on one of Europe’s most dramatic natural stages.
6. Volcán de Lodo El Totumo, Colombia
Okay, this one’s a bit different—but stick with me. Volcán de Lodo El Totumo isn’t your typical volcanic crater. Instead of lava and steam, this small mound releases bubbling mud that you can actually bathe in. Think of it as an offbeat spa day, with a volcanic twist.
Nestled near Cartagena, this mud bath is said to have therapeutic properties, and floating in the dense, warm mud feels a bit like being on another planet. After your soak, wash off in the nearby lagoon, and enjoy the slightly surreal feeling of having taken a volcanic adventure that’s equal parts quirky and soothing.
7. Askja, Iceland
Iceland is known for its otherworldly landscapes, and the Askja caldera is a standout. Hidden in the remote, volcanic highlands, Askja is home to Víti, a sapphire-blue geothermal lake surrounded by creamy white and rust-colored slopes. The name Víti means "hell," but trust me, this place feels more like heaven for adventurous travelers.
The lunar-like terrain here was so surreal that NASA used it as a training ground for astronauts heading to the moon. Hiking to Víti takes you across black lava fields and rugged terrain, but the payoff is worth it. On a hot summer day, you can even take a dip in the lake’s warm waters and feel like you’re swimming on another planet.
