Idaho is full of marvels just waiting to be explored, but our natural wonders are truly the heart and soul of our state. From the plunging depths of our river canyons and secret caves to the soaring heights of our picturesque mountains, crystalline lakes, towering sand dunes, and everything in between, it’s easy to see just how beautiful and baffling Idaho’s landscape can be.

However, few people realize that Idaho is also home to a uniquely expansive granite city that is just as fascinating as the Badlands of South Dakota and the arches of Utah. You can find them just north of the Idaho-Utah border, and they’re a must-see if you get a chance to travel through southern Idaho. Check it out:

Welcome to the "Silent City of Rocks," officially known as the City of Rocks National Reserve.

Adjacent to Castle Rocks State Park and near Almo, this sweeping 14,500-acre reserve was established in 1988 as a protected national natural landmark to preserve its unique beauty and historical importance.

Not to be confused with the smaller "Little City of Rocks" in Gooding, over 100 miles north.

Just as unique but not federally protected, this rocky haven is worth its own trip as well... but that's a story for another time.

This silent city isn't quite as "silent" as it seems, though...

Here, the echoes of history ring loud and clear.

California Trail wagon trains of the 1840s and 1850s traveled through this part of southern Idaho into Nevada. Names and initials of emigrants can be found written in axle grease on Register Rock, and ruts from wagon wheels can be seen in some areas as well. But even before the great migration, Shoshone and Bannock tribes used the landscape as a buffalo hunting ground and gathered the nuts of the native pinyon pine trees. Both cultures also took advantage of the natural water basins formed by the rocks to collect water and took shelter in the formations themselves.

As well as 2.5 billion years of turbulent geology and rugged, Idaho beauty -- in fact, the Green Creek Complex of the reserve is home to some of the oldest rocks in the west.

The landscape of City of Rocks is sculpted granite that bored through the earth's surface during two distinct geologic time periods: Oligocene and Archean.

The slow erosion process of these granite masses shaped them into the forms we know and love today, each with their own imaginative names:

Breadloaves, Window Arch, Bath Rock, Elephant Rock...

Human remnants are still visible around every corner in this region.

But as those remnants fade, this somber city of granite is a fascinating playground for all ages and abilities, as well as a photographers' haven.

It was the unique rock formations that led travelers to write about this spot in their journals, and what brings visitors today.

Just as unique but not federally protected, this rocky haven is worth its own trip as well... but that's a story for another time.

Spires, towers, pyramids, and domes create a monolith sculpture garden unlike any other in the country, all perfect for rock climbing, scrambling, and hiking.

Over 1,000 established rock climbing routes are in place, others are climbable no matter your age or ability. 22 miles of hiking trails also weave in and around the formations, leading to stunning overlooks. Just don't forget your climbing permit!

The impressive rock formations come in all shapes and sizes, some up to 600 feet tall.

Camping within the reserve makes for easy access and long, adventure-filled days.

City of Rocks offers 64 campsites, many of which are tucked in among the granite fins and boulders and shaded by aspen, juniper, mountain mahogany, and pine. All sites have a ground grill/fire-ring and picnic table, and many have defined tent pads. Reservations are highly recommended, however.

But the true magic of City of Rocks is in its natural beauty.

The surrounding desert landscape intermingles with the rock formations, which blossoms into a vibrant carpet of wildflowers every spring. And in fall, the region erupts into a colorful world of cottonwoods.

But you'll also see some fantastic wildlife roaming around, too!

Basically, there's something here for everyone.

History buffs, climbers, nature enthusiasts, you name it.

And a sunset here should never be overlooked.

There's so much more to explore! If climbing isn't your thing, opt for an auto tour on the 49-mile City of Rocks Back Country Byway, which starts in Albion.

How incredible is it that Idaho is home to not one, but multiple rock cities? Have you ever visited the City of Rocks? What did you think?
