This trail follows Little Slate Creek for 11 miles and starts off the Little Slate Saddle off the Grangeville/Salmon Rd (FS221). This trail is a non-motorized trail and does see yearly maintenance once the snow clears.
The trail is challenging and is in thick tree cover for most of its length. You'll pass through some meadows where the trail will fade out in early summer so keep your eyes open for trail signs and also follow the gps track where you are unsure. The creek can be high in the early season, so keep this in mind if you try to get out early in the season.
The crossing of Boulder Creek towards the bottom of the trail can be difficult in early season so keep this in mind if you are descending from the top since there are no good options around this creek crossing. There will be some short ups along the way, but overall you are on a downward trend.
