RockyMap National Parks Guide: Best Trails in Every Park
National Parks Guide: Best Trails in Every Major Park
The US National Park System contains 63 national parks and thousands of miles of maintained trails. In 2025, those parks recorded over 323 million recreation visits. This guide selects the best trails in each major park region — the hikes that deliver the defining experiences of each landscape without requiring mountaineering skills or multi-day commitments.
How We Selected: We reviewed options using trail conditions, gear testing, and topographic data. Primary factors were weather durability, ease of use in the field, trail accuracy, battery life. We do not accept payment or free products from any brand featured here.
Every trail listed is a day hike accessible to reasonably fit adults. Difficulty ratings, distances, and permit requirements are current for the 2026 season.
The West: Rockies and Desert Southwest
Rocky Mountain National Park, Colorado
Sky Pond Trail — 9.4 miles round trip, 1,750 ft elevation gain, strenuous The signature Rocky Mountain experience. The trail passes Alberta Falls, climbs through The Loch valley, scrambles up Timberline Falls, and ends at Sky Pond, a glacial tarn ringed by 13,000-foot peaks. The final approach requires a brief scramble over a waterfall — hands may be needed, but it is not technical climbing. Start before 6 AM in summer to secure trailhead parking. Timed entry reservations are required May through October.
Zion National Park, Utah
Angels Landing — 5.4 miles round trip, 1,488 ft elevation gain, strenuous The exposed chain-assisted ridge walk to the summit is Zion’s most famous trail. In 2026, a permit lottery is required (apply 3 months in advance through Recreation.gov). The trail itself alternates between paved switchbacks and narrow ridge with 1,000-foot drop-offs on both sides. Not suitable for anyone uncomfortable with heights or vertigo. For a less exposed alternative with equally impressive canyon views, hike the Observation Point trail. For more Zion details, see our Zion trail guide.
Grand Canyon National Park, Arizona
South Kaibab Trail to Skeleton Point — 6 miles round trip, 2,040 ft elevation gain, strenuous The South Kaibab follows a narrow ridge with panoramic canyon views in every direction — widely considered the premier Grand Canyon trail experience. Turn around at Skeleton Point for a challenging day hike. Do not attempt the rim-to-river-to-rim in a single day. Heat, elevation change, and distance make it genuinely dangerous for unprepared hikers. Carry at least 3 liters of water per person. Our full Grand Canyon guide covers seasonal recommendations.
Yellowstone National Park, Wyoming
Grand Prismatic Overlook Trail — 1.6 miles round trip, 150 ft elevation gain, easy The most photographed feature in Yellowstone is best viewed from above, and this short trail delivers the full rainbow palette of the world’s third-largest hot spring. Combine it with the Fairy Falls trail for a 5-mile moderate hike. For backcountry options, see our Yellowstone backcountry guide.
Glacier National Park, Montana
Grinnell Glacier Trail — 10.6 miles round trip, 1,840 ft elevation gain, strenuous Alpine meadows, waterfalls, emerald-green glacial lakes, and the rapidly retreating Grinnell Glacier itself make this the park’s most rewarding hike. Wildlife sightings (mountain goats, bears from a distance) are common. The trail is typically snow-free from mid-July through September. Going-to-the-Sun Road must be open to access the trailhead. See our Glacier trail guide for seasonal access.
Arches National Park, Utah
Delicate Arch Trail — 3 miles round trip, 629 ft elevation gain, moderate The hike to Utah’s most iconic natural arch crosses exposed slickrock with no shade, but the payoff at the end — the freestanding 46-foot arch framing the La Sal Mountains — is worth every sun-exposed step. Carry more water than the short distance suggests. Late afternoon provides the best lighting and slightly less crowding.
The Pacific States
Yosemite National Park, California
Mist Trail to Vernal and Nevada Falls — 5.4 miles round trip, 1,900 ft elevation gain, strenuous Spring through early summer delivers the full experience: a soaking mist from Vernal Fall as you climb 600 granite steps, followed by views of the 594-foot Nevada Fall from above. The granite staircase is slippery when wet, and the mist is not optional — you will get drenched. Bring a light rain layer. See our Yosemite guide for more trails.
Mount Rainier National Park, Washington
Skyline Trail Loop — 5.5 miles, 1,700 ft elevation gain, strenuous Starting from Paradise, this loop climbs through wildflower meadows (peak bloom July–August) with Rainier’s glaciated summit filling the northern horizon. The trail offers views of Nisqually Glacier and, on clear days, Mount Adams, Mount St. Helens, and Mount Hood. Snow can persist into August on higher sections. Our Mount Rainier guide covers the full trail network.
Olympic National Park, Washington
Hoh Rain Forest Hall of Mosses Trail — 0.8 miles, minimal elevation, easy The shortest hike on this list delivers one of the most otherworldly landscapes: old-growth Sitka spruce draped in club moss, ferns carpeting every surface, and light filtering through the canopy. Combine it with the Spruce Nature Trail (1.2 miles) for a complete rain forest experience. No permit needed.
The East and Southeast
Great Smoky Mountains National Park, Tennessee/North Carolina
Alum Cave Trail to Mount LeConte — 11 miles round trip, 2,763 ft elevation gain, strenuous The most visited national park (11.5 million visitors in 2025) still hides remarkable trail experiences behind distance and elevation. This trail passes through old-growth forest, crosses exposed bluffs with views across the Smokies, and ends at LeConte Lodge — the highest guest lodge in the eastern US. The full out-and-back demands fitness; turning around at Alum Cave Bluffs (4.4 miles round trip) provides the highlight at half the effort.
Shenandoah National Park, Virginia
Old Rag Mountain — 9.1 miles, 2,510 ft elevation gain, strenuous A granite scramble through a rock maze near the summit makes Old Rag the most technical and rewarding day hike on the East Coast. The scramble section requires using hands and navigating between boulders — not true rock climbing, but physically demanding and not suitable for young children or anyone uncomfortable with exposure. Permits required through Recreation.gov.
Acadia National Park, Maine
Precipice Trail — 1.6 miles round trip, 1,058 ft elevation gain, strenuous Iron rungs, ladders, and exposed ledges make this the most exciting trail on the eastern seaboard. The trail closes during peregrine falcon nesting season (typically April through mid-August). When open, it rewards with summit views across the Atlantic, Frenchman Bay, and Acadia’s granite landscape. Not suitable for anyone afraid of heights. Our Acadia guide covers gentler alternatives.

Best Times to Visit
Spring (April–May) and fall (September–October) provide the best combination of moderate temperatures, manageable crowds, and seasonal displays (wildflowers in spring, foliage in fall). Summer brings the best weather for high-elevation trails but also peak crowding. Winter opens a different experience entirely — see our winter hiking guide.
