The Humbug Trail generally runs east/west in Yreka's Greenhorn park. Riding east to west (as mapped) results in climbing punctuated by short descents; riding west to east starts with a steep climb that rewards the rider with fun descending for most of trail.
At the eastern end of trail, you'll find the water tower and intersections with the Lynn Skinner and Big Ditch Trail
. The Goat Trail
intersects Humbug toward the middle of the trail. At the western end of the trail you'll meet up with the Flume Trail
and the AARP Trail
a few hundred feet before (east).
The Humbug Trail is not very technical, but there are some rocks, roots, and a couple switchbacks. Trail surface is mostly hardpack, but has some drainage issues leading to ruts and mud in the wetter months. Humbug Trail has awesome views of the surrounding mountains in the distance and the town bellow, with multiple bench equipped overlooks.
Humbug Trail is a popular hiking and dog walking trail, so be careful on blind corners.
