The Hasley Basin Trail is often used by hikers going over West
Maroon Pass and continuing on to either Geneva or Snowmass
Lake. It is a fairly steep trail most of the way, especially over
saddle connecting the East Fork drainage and Hasley Basin.
Hasley Basin trail is a pleasant and relatively quiet hike that
reaches a saddle offering nice views of the East Fork drainage.
The waters of the East Fork reach the Crystal River via the
Fork. The trail may be difficult to locate near the saddle. The
observant hiker has a good chance of seeing wildlife. There is
almost always snow on the north facing side of the bowl late
the summer season.
Hikers coming from West Maroon Pass can use the Hasley
Cutoff. The cutoff begins about 400 feet below Frigid Air Pass
where the last big switchback to the pass begins and a small,
usually dried up tarn is located. The trail is
well defined to a saddle into Hasley Basin (not the same saddle
that is on the Hasley Basin Trail). From there, the trail is hard
to follow as it contours west to it's junction roughly 200 feet
below the Hasley Basin Trail saddle.
To access this trail from Lead King Basin, start at the Geneva
Lake/North Fork Trailhead. Follow the North Fork trail until
you reach the stream crossing. Shortly after fording the creek,
you will reach the well known Love's cabin and the start of the
Hasley Basin trail.
