For years, Southern Idaho flew under the travel radar — known mostly for farmland, quiet towns, and scenic drives. But once you dig a little deeper, you’ll discover a different kind of adventure waiting: volcanic terrains, towering rock spires, mist-shrouded canyons, and even sandboarding dunes.
Julie and I had no idea a state known for potatoes could deliver such a range of jaw-dropping moments. Whether you’re craving peaceful hikes or thrill-seeking surprises, this patch of the Gem State offers a refreshing blend of the unexpected.
Let’s kick things off with one of its most surreal landscapes — a place that feels like Earth’s own lunar outpost.
Craters of the Moon: Idaho’s Otherworldly Landscape
If you’ve ever wondered what it’s like to walk on another planet, Craters of the Moon delivers. This vast expanse of volcanic rock, lava tubes, and spatter cones feels like a lunar dreamscape. Julie and I wandered through caves and hiked along crater rims, marveling at the strange beauty sprouting from black ash. It’s also an International Dark Sky Park — perfect for stargazing.
Curious what it’s really like to explore this surreal terrain? Read our full experience at Craters of the Moon.
Shoshone Falls: The Niagara of the West
Nature’s prism: a rainbow dances through the mist at Shoshone Falls.
Towering at 212 feet, Shoshone Falls is one of the most powerful waterfalls in the country — and it’s tucked right into Twin Falls. The viewpoints above are stunning, but the real magic happens when you hike down or catch the mist at sunset.

City of Rocks & Castle Rocks: Granite Giants of the Albion Mountains
Almo, Idaho, hides a world of towering granite spires and monoliths that feel like nature’s own sculpture garden. Whether you’re rock climbing or simply admiring the formations from scenic drives and short hikes, these parks offer a peaceful escape. Julie and I were surprised by how different — and equally captivating — each park felt.
Perrine Bridge & Centennial Waterfront Park: Where BASE Jumpers Fly
The Snake River slips through time beneath the Perrine Bridge’s sturdy arch.
Twin Falls is home to one of the only bridges in America where BASE jumping is legal year-round. Watching seasoned jumpers launch from the Perrine Bridge is surreal — especially when you’re kayaking below in Centennial Waterfront Park. We even saw a parachuter drift down during our boat ride through the legendary Snake River canyon.

Bruneau Dunes: Sandboarding and Stargazing
Bruneau Dunes stand ready — the thrill of sandboarding whispered in every grain.
Southern Idaho’s landscape flips again at Bruneau Dunes State Park, home to North America’s tallest single-structured sand dune. You can hike or sandboard the 470-foot giant, then stick around for stargazing at the park’s observatory. Julie and I recommend visiting early in the day — the gray sand heats up fast.
Balanced Rock: Nature’s Gravity-Defying Sculpture
Just south of Buhl, you’ll find a 40-ton rock balancing on a tiny pedestal. It’s one of those places that makes you stop and stare — and wonder how it hasn’t toppled. The surrounding park is perfect for a picnic or a peaceful overnight stay.
Hagerman Fossil Beds: Ancient History Along the Snake River
This national monument shares a visitor center with Thousand Springs State Park and offers a fascinating look at Pliocene-era fossils. Scenic overlooks reveal steep bluffs and layered rock formations, while trails like the Emigrant’s Trail connect you to the Oregon Trail’s legacy.
Thousand Springs State Park: Magic Valley’s Hidden Gems
Crystal waters tumble through basalt cliffs — a quiet marvel in the heart of Thousand Springs.
With six distinct units, Thousand Springs feels like multiple parks rolled into one. Malad Gorge and Ritter Island were our favorites — dramatic canyons, waterfalls, and crystal-clear springs that defy expectations.
