It’s an understatement to say America’s favorite national parks are extremely popular. Great Smoky Mountains? Nearly 13 million annual visitors. Grand Canyon? Nearly 5 million. Zion? 4.6 million. Rocky? 4.3 million. If you want one-on-one time with Mother Nature, national parks are probably not the way to do it.
Instead, consider swapping your park trip for a forest trip—often it’s the same land, just across an imaginary border. Though the United States has 154 national forests to choose from, here are some top-tier favorites.
Want to explore Colorado’s famed Fourteeners without the crowds? Head to the San Juan National Forest—specifically the Weminuche and Lizard Head wilderness areas. Protecting the headwaters of the Rio Grande and San Juan Rivers, Weminuche alone is three-quarters the size of Rhode Island. You’ll find lakes and hiking trails galore up here, plus those 14,000-foot (4,300-meter) peaks, like Mount Eolus.
For something a little less adrenaline-producing, ride the Durango and Silverton Narrow Gauge Railroad through some of the country’s most gorgeous canyon scenery, or take a drive down the San Juan Skyway, aka the “Million Dollar Highway.”
At 5,550 acres (2,200 hectares), Arkansas’ Hot Springs National Park is the second-smallest national park in the country. If you’re looking to do some real wandering, try the nearby 1.2-million-acre (500,000-hectare) Ozark-St. Francis National Forest instead. There you’ll find waterfalls, high bluffs, gentle mountains, spring-filled caverns, dense hardwood forests, and swirling lakes and rivers.
Popular activities include hiking Pam’s Grotto, climbing Sam’s Throne, or kayaking the Buffalo National River, one of the longest undammed rivers in the Lower 48. It offers both gentle floats and rapids, and when night falls, it doubles as a designated International Dark Sky Park.
Yellowstone regularly sees 1 million visitors a month come summer—and the best way to avoid them is to adventure through Wyoming’s Bridger-Teton National Forest, one of the Lower 48’s largest at 3.4 million acres (1.4 million hectares). You'll find hundreds and hundreds of hiking and biking trails, lakes and rivers for fishing and picnicking, countless camping sites, and even glaciers.
If you’re looking for some serious—and seriously beautiful—hiking, check out the Wind River Range in the Pinedale Ranger District. It’s loaded with glistening lakes and glaciers and more than 40 peaks that tower above 13,000 feet (4,000 meters).
Sitting between Yosemite National Park and Kings Canyon National Park, Sierra National Forest often gets overlooked, but it shouldn’t. Famed photographer Ansel Adams and naturalist John Muir both loved this area so much, wilderness areas within the forest are named after them.
Here, you’ll get a little bit of Yellowstone, Sequoia, and Kings Canyon all rolled into one. Scope out giant redwoods in McKinley and Nelder groves, hot springs at the Mono Hot Springs campground, granite masses at Fresno Dome, and Sierra Nevada views at White Bark Vista.
Though Olympic National Park isn’t the most crowded park on this list, it has a few spots that get Yellowstone levels of foot traffic. For an alternative, try the Olympic National Forest, which almost completely surrounds the national park.
For rainforest vibes, check out the 4-mile (6-kilometer) Quinault Rain Forest Loop Trail; for a wildflower-filled mountain trek, hike one of the 6,000-foot (1,800-meter) peaks of the Mt. Skokomish Wilderness. With mostly lower elevations, many spots here can be hiked year-round. Of course, you’ll also find plenty of campgrounds, lakes for relaxing, old-growth Douglas firs for forest bathing, and more.
The Great Smoky Mountains National Park can be a hassle to navigate—the 11-mile (18-kilometer) Cades Cove Loop can take hours to wind through in traffic. Considering the national park’s appeal is largely, well, trees, the surrounding Cherokee National Forest offers plenty of those, plus ample other opportunities for adventure.
Here’s a short list of things you can do in the Cherokee National Forest: hike the Appalachian Trail; white-water raft the Ocoee River; hike the Iron Mountains; kayak Watauga Lake; bike the 30-mile (48-kilometer) Tanasi Trail; and count waterfalls in the Rock Creek Gorge Scenic Area. (Hint: There are 16.)
Covering 2 million acres (800,000 hectares), Utah’s Dixie National Forest offers plenty to do and tons of room to spread out. And while nearby Bryce Canyon is supernaturally fantastic for red rocks, so too is Dixie—Red Canyon, which lies en route to Bryce, might as well be the national park’s little brother.
And then there are spots such as Yant Flat and the Candy Cliffs, which are reminiscent of Arizona’s The Wave—without the required lottery access. For a family-friendly adventure, hit Hell’s Backbone Road, a scenic “backroad,” on a dry day for a high-elevation, panoramic adventure.
