10 Underrated Places in the U.S. to Explore This Summer

Introduction

When it comes to summer travel, many Americans flock to iconic destinations like the Grand Canyon, Yellowstone, or Miami Beach. But beyond the popular hotspots lies a treasure trove of lesser-known locales that promise unforgettable experiences, minus the crowds. Whether you're looking for stunning landscapes, rich history, or charming small towns, this list of underrated U.S. destinations will inspire you to take the road less traveled. Pack your bags and discover the hidden gems that await this summer.

1. Bisbee, Arizona

Tucked into the Mule Mountains near the Mexican border, Bisbee is a quirky artist enclave with a rich mining history. Once a booming copper town, today it's known for its Victorian architecture, colorful street art, and vibrant creative scene. Visitors can tour the Queen Mine, browse galleries, or stay in one of the many eccentric boutique hotels that dot the historic district.

In the summer, the cooler mountain air provides a pleasant escape from Arizona’s desert heat. Explore nearby hiking trails, grab a craft beer at a local brewery, or attend one of the town’s lively weekend markets and music events. Bisbee’s offbeat charm makes it a perfect getaway for those craving something a little different.

2. Mendocino, California

Overlooking the rugged Northern California coast, Mendocino offers dramatic cliffs, secluded beaches, and a peaceful, artsy vibe. While nearby areas like Big Sur draw bigger crowds, Mendocino remains a tranquil retreat. The town's 19th-century buildings and windswept bluffs evoke a timeless charm.

Summer visitors can enjoy kayaking along the Big River, wine tasting at local vineyards, or hiking through the redwood forests of Russian Gulch State Park. Mendocino’s slower pace and breathtaking scenery make it an ideal destination for those seeking serenity by the sea.

3. Great Sand Dunes National Park, Colorado

Often overshadowed by Colorado’s more famous mountain parks, Great Sand Dunes National Park boasts the tallest dunes in North America. Towering as high as 750 feet, these massive dunes create a surreal, almost Martian landscape perfect for sledding, sandboarding, or stargazing.

Summertime brings warmer temperatures ideal for splashing in Medano Creek, a seasonal stream that runs at the base of the dunes. With its unique mix of desert and alpine environments, this park offers adventure, solitude, and one-of-a-kind photo opportunities.

4. Decorah, Iowa

Set in Iowa’s Driftless Region, Decorah surprises visitors with its rolling hills, limestone bluffs, and outdoor adventure. Far from the flat cornfields most associate with the Midwest, Decorah offers kayaking on the Upper Iowa River, biking along the Trout Run Trail, and exploring ice caves.

The town itself is rich in Norwegian heritage, featuring folk art, festivals, and the Vesterheim Norwegian-American Museum. In summer, lush greenery and small-town warmth make Decorah an unexpectedly delightful destination.

5. Silver Falls State Park, Oregon

Just outside Salem, Silver Falls State Park is home to the famous Trail of Ten Falls, a spectacular 7.2-mile loop that leads hikers past (and even behind) a series of stunning waterfalls. Despite its beauty, the park remains relatively uncrowded compared to Oregon’s coastal and mountain destinations.

Summer is the perfect time to hike, picnic, and camp in this fern-filled wonderland. The shaded forest and cool mist from the falls offer refreshing relief from the heat, while the park’s rustic cabins make for a charming overnight stay.

6. Cuyahoga Valley National Park, Ohio

Tucked between Cleveland and Akron, Cuyahoga Valley is one of the most accessible yet underrated national parks in the U.S. It offers a surprising blend of waterfalls, forest trails, and historic landmarks along the Ohio & Erie Canal Towpath Trail.

Summer activities include biking, birdwatching, and riding the scenic Cuyahoga Valley Scenic Railroad. With a variety of ecosystems and ample picnic spots, it’s a peaceful haven just minutes from urban hustle. Perfect for families and nature lovers alike.

7. Bayfield and the Apostle Islands, Wisconsin

Located on Lake Superior’s south shore, Bayfield serves as the gateway to the Apostle Islands National Lakeshore. This region is a water lover’s paradise, offering sea kayaking, sailing, and beachcombing among the 21 pristine islands.

Summer is the best time to explore the sea caves, lighthouses, and old-growth forests that dot the islands. Bayfield itself is a charming harbor town with berry farms, art galleries, and lakefront dining. It’s a peaceful escape that combines natural beauty with small-town charm.

8. Tallulah Gorge State Park, Georgia

One of the Southeast’s most spectacular canyons, Tallulah Gorge is a two-mile-long, 1,000-foot-deep chasm carved by the Tallulah River. Though it rivals many national parks in beauty, it remains relatively unknown outside Georgia.

Adventure seekers can hike to suspension bridges, climb into the gorge with a permit, or cool off at the Bridal Veil Falls swimming hole. With lush summer greenery and dramatic vistas, this hidden gem is perfect for a weekend getaway.

9. North Cascades National Park, Washington

Despite being one of the least visited national parks in the country, the North Cascades is a jewel of the Pacific Northwest. Jagged peaks, turquoise alpine lakes, and over 300 glaciers make this park a dream for hikers and photographers.

Summer brings clear skies and accessible trails like Maple Pass Loop and Cascade Pass. With fewer crowds than neighboring Mount Rainier and Olympic National Parks, the North Cascades offer solitude and raw wilderness at its finest.

10. Cumberland Island, Georgia

Accessible only by ferry, Cumberland Island is a protected national seashore known for its wild horses, empty beaches, and historic ruins. The island limits daily visitors, preserving its untouched feel and making it a haven for nature lovers.

Summer visitors can hike through maritime forests, camp under the stars, or swim in the Atlantic without seeing another soul. From the grand Dungeness mansion ruins to the peaceful salt marshes, Cumberland is a magical step back in time.
