These are some trips you can take to enjoy landscapes from 'other planets'

To marvel at the landscapes of other worlds and experience adventures in different parts of our solar system, it's not necessary to travel to outer space. Over millions of years, geological activity and erosion have created places on our own planet worthy of appearing in an imaginary "travel guide to terrestrial destinations."

Some caves, mountains, volcanoes, deserts, glaciers, and rock formations, located in different corners of our planet, offer otherworldly landscapes that can be visited, experiencing a truly "extraterrestrial experience," according to the online platform Civitatis (www.civitatis.com), which specializes in activities and excursions in Spanish.

Here are five of them, although there are many more on our rich and diverse planet.

Amidst a wide geological and landscape diversity, between desert areas with volcanic rocks and dense, verdant forests, rises Mount Etna, the symbol of Sicily throughout the world. It is the largest active volcano in Europe and one of the highest in the world, included on the UNESCO World Heritage List. Mount Etna is a stratovolcano—a volcano whose height varies over time due to eruptions— and on its eastern slope, whose walls are characterized by deep canyons, are two of its most striking features: the "Ice Cave," a cavity in which a perennial glacier has formed, and the "Bove Valley," a basin-shaped volcanic depression. Learn about the volcanic craters formed by the eruptions, such as the Silvestri cones, which emerged in 1892; Photographing the black sand deserts of Etna, observing its high ravines and entering the volcanic tubes formed by ancient lava flows is an experience that reveals the beauty created by geological activity and the fury of nature, concludes Civitatis.

Located in Wyoming, Montana, and Idaho, Yellowstone National Park is home to a variety of wildlife, including grizzly bears, wolves, bison, and elk. It also offers the colorful Grand Canyon of the Yellowstone, the wild beauty of Yellowstone Lake, the striking eruptions of Old Faithful, the world's most popular geyser, and hundreds of other geysers and hot springs. Yellowstone is famous for its geysers—from which spurt hot water or steam—but it's also home to a striking array of mountains, rivers, gorges, crystal-clear waters, sprawling grasslands, bubbling mudflats, and roaring waterfalls, as well as hundreds of miles of trails that wind through its many wonders created by Mother Nature. Established in 1872 as the United States' first national park, this natural area is home to North America's largest volcanic system and the Grand Prismatic Spring, the largest hot spring in the country. It is famous for its vivid colors—ranging from blue to green to red, created by the action of pigmented bacteria.

This sprawling park, located in the city of Zhangjiajie (Hunan Province, China), is famous for its unique peaks, stunning landscapes, lush forests known as the Garden of Heaven, and pillar-like rock formations. One of the main attractions of this spectacular natural area, included on the UNESCO Global Geoparks list, is Tianmen Cave, also known as Heaven's Gate, a gigantic natural hole formed in the rock, located high on Tianmen Mountain. During a visit to the park, you can ascend Tianmen Mountain on one of the longest and steepest cable cars in the world and access the ancient Tianmen Mountain Temple, a Buddhist sanctuary built during the Tang Dynasty.

In the stunning Wadi Rum Desert, located in southwest Jordan and also known as the Valley of the Moon, wind and water have carved out a labyrinth of rock formations rising to 1,750 meters, offering visitors vast open spaces, canyons, water reservoirs, and rock paintings dating back more than 4,000 years. This desert, with its immense sense of peace and unparalleled sunsets, can be explored by camel, hiking, off-road vehicle, or hot-air balloon, taking in sights such as the Burdah Stone Bridge (the highest in Wadi Rum) and the Seven Pillars of Wisdom (spectacular rock formations). One of Jordan's most beautiful natural sites, Wadi Rum has been the setting for major films such as Lawrence of Arabia, Rogue One (from the Star Wars saga), and The Martian.

Vatnajökull, Iceland's largest glacier and one of Europe's largest in area, is an impressive mass of ice that sits atop a chain of high-altitude volcanoes and displays a wide variety of formations and landscapes, such as its dreamy lagoons, where icebergs can be seen, and its caves, formed by water running through or beneath the glacier.

Breiðamerkurjökull, in southern Iceland, is one of the main entrances to the Vatnajökull glacier. From there, you can access the labyrinth of tunnels formed within the ice by melting snow and accumulating snow. When snow compacts, it traps air bubbles through which light penetrates, creating an extraordinary visual spectacle. Visiting the crystalline glacial caves, where the sun's rays shine in shades of green or electric blue; walking on the frozen, ridged formations; or visiting the Jökulsárlón glacier lagoon, where large chunks of ice float, breaking off from the Breiðamerkurjökull glacier tongue, allow you to discover true works of nature.
