by Billings, MT – Montana is renowned for its breathtaking landscapes and rugged beauty, but beyond the sweeping mountains and vast prairies, the state is home to some of the most unique rock formations in the U.S. These geological wonders, sculpted by millions of years of natural forces, reward those willing to venture off the beaten path. From sandstone pillars to ice caves, here are ten formations that prove every mile of rough driving and every hike is worth it.
1. Medicine Rocks State Park (Ekalaka)
Medicine Rocks features otherworldly sandstone formations carved with holes, arches, and tunnels over millions of years. This culturally rich site also holds petroglyphs and pictographs left behind by Indigenous peoples and early settlers, making it both a natural and historical treasure.
2. Terry Badlands (Terry)
The Terry Badlands showcase colorful, banded sandstone bridges, spires, and tabletops spread across an undeveloped wilderness. Popular among photographers and hikers, the rugged terrain comes alive during sunrise and sunset when the rocks glow with brilliant shades of orange and red.
3. Ringing Rocks (Butte)
Just east of Butte lies one of Montana’s quirkiest attractions. At Ringing Rocks, only certain rocks produce a bell-like tone when struck. This free, year-round destination offers an interactive experience unlike anywhere else in the state.
4. Pryor Mountains (Pryor)
Rising abruptly from the prairie, the Pryor Mountains feature canyons, ice caves, and winding creeks. The formations here are geologically distinct from Montana’s glacier-carved mountains, offering a mix of biodiversity, history, and rugged beauty.
5. Pompey’s Pillar (Nibbe)
This iconic sandstone outcrop stands 130 feet above the Yellowstone River. Beyond its natural beauty, it’s a historic landmark bearing William Clark’s signature from the Lewis and Clark Expedition, making it one of Montana’s most significant cultural stops.
6. White Cliffs (Fort Benton)
The White Cliffs, along the Upper Missouri River, are towering sandstone pillars capped with dark loam. Meriwether Lewis once described them as “romantic” and “remarkable.” Today, they remain a bucket-list destination for river floaters and hikers.
7. Rock City (Valier)
A hidden gem near Valier, Rock City features mushroom-shaped hoodoos and flat-topped formations. Less visited than other badlands, it offers a peaceful, almost surreal atmosphere for explorers who prefer solitude.
8. Makoshika State Park (Glendive)
Montana’s largest state park, Makoshika, is filled with dramatic badlands and fossil-rich rock formations dating back to the Cretaceous period. It’s a paradise for geology lovers and fossil hunters alike.

9. Ice Caves Trail (Big Snowy Mountains, Crystal Lake)
According to River City Omaha, The Ice Caves Trail leads to year-round frozen caves at the summit of the Big Snowy Mountains. Though the hike is strenuous, adventurers are rewarded with breathtaking views of multiple ranges and the rare thrill of walking through naturally frozen caves even in summer.
10. Granite Peak (Beartooth Mountains)
As Montana’s highest point at 12,799 feet, Granite Peak dominates the Beartooth Range. The ancient granite cliffs and panoramic vistas make it one of the most challenging yet rewarding climbs in the Rockies.
Why Montana’s Rock Formations Are Worth the Trek
These ten sites reflect Montana’s diverse geology, deep history, and untouched wilderness. While some require long drives or demanding hikes, each destination offers unforgettable views, natural wonders, and a glimpse into the state’s ancient past.
