The Best National Parks for Hiking: A Realistic Guide for Every Experience Level

America’s national park system contains over 18,000 miles of maintained hiking trails ranging from paved accessible walks to technical mountaineering routes. Matching your experience and fitness to the right park and trail within it produces the hiking trip that turns occasional hikers into dedicated ones.

For Beginners: Acadia, Shenandoah, Great Smoky Mountains

Acadia National Park on the Maine coast provides a density of excellent hiking in 47,000 acres that is unmatched in the eastern US. The carriage roads alone — 45 miles of gravel paths — provide beautiful low-stress hiking. Great Smoky Mountains offers well-maintained, well-marked trails through old-growth forest at modest elevations. Shenandoah’s Skyline Drive provides 500 miles of trails accessible from a paved road running the length of the park.

For Intermediate Hikers: Olympic, Rocky Mountain, Glacier

Olympic National Park on Washington’s Olympic Peninsula contains three distinct ecosystems — temperate rainforest, alpine meadows, and Pacific coastline — within a single park. Rocky Mountain National Park offers trails reaching 14,000-foot summits. Glacier National Park offers arguably the most spectacular mountain landscapes accessible by trail in the lower 48, with trails leading into some of the most beautiful backcountry in North America.

For Advanced Hikers: North Cascades, Grand Teton, Wrangell-St. Elias

North Cascades National Park in Washington has fewer maintained trails than most parks and a higher proportion of routes requiring cross-country navigation and glacier travel — a genuine wilderness experience in the lower 48. Grand Teton offers technical approaches to spectacular summits combined with easier valley trails. These parks reward hikers who have built backcountry skills progressively rather than jumping to them from day hiking experience.
