Trail guides for US national park hikers
A US hikers guide focused on a few high-demand national-park trails — distance, access rules and safety, checked against nps.gov.
Trail guides
Only these guides are maintained as the public hub. Each page lists its National Park Service sources.
The Narrows
A Virgin River gorge hike in Zion National Park: walls about 1,000 feet tall and the river sometimes only 20–30 feet wide. Bottom-up from the Temple of Sinawava needs no permit; the 16-mile top-down from Chamberlain’s Ranch does.
Grinnell Glacier
A full-day Many Glacier hike in Glacier National Park to the Grinnell Glacier Viewpoint: about 5.3 miles one way and 1,600 feet of elevation gain from the trailhead, or about 3.6 miles one way with the concession boat.
Emerald Lake Trail
A Bear Lake corridor hike in Rocky Mountain National Park past Nymph and Dream Lakes to Emerald Lake: about 1.7 miles one way and 771 feet of elevation gain from the Bear Lake trailhead at 9,475 feet.
We compile trail facts from official sources — primarily the National Park Service — and cross-check distance, elevation gain and access rules before publishing. Every guide shows the date it was last verified. We are hikers writing for hikers; we are not a government agency and our guides are planning references, not a substitute for current official trail and weather advisories.
