The North Fork Trail follows the North Fork of the Crystal until it goes over Frigid Air Pass. One large waterfall can be seen about a mile east of Love's Cabin, a well known landmark at the junction of Hasley Basin and the North Fork of the Crystal. Fravert Basin along the way is a wide, open, scenic valley. The back of the Maroon Bells can be viewed from the basin. This trail begins at the same spot as the Geneva Lake trail. The grade is gentle until the waterfall, and is again gentle until the ascent over Frigid Air Pass. It can be part of a loop trail connecting West Maroon Pass and Snowmass Lake.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
