This is another standard around Bozeman. West facing so it typically dries out before anything else in the spring. Depending upon the weather it should be dry by late May. Follow singletrack into the canyon. Before you know it the trail ascends very steeply before dropping back into the drainage. I've seen few actually ride this first part successfully but I'm sure you totally got it. <br />
Good trail up to the meadow view. Everything from technical rocks to pine needle carpet. After a couple miles trail comes out onto ridge line which it follows to the north with Mt. Baldy looming above. At ~mile 3.5 find trail marker which indicates trail into the drainage to the east. Technical, loose trail descends rapidly to a creek which you follow for only short distance before the trail continues east steeply. Most will probably have to hike-a-bike until the pitch mellows. For those who like moderate downhills of pine needle carpet that you don't have to overly brake this next section is for you. This is "B" trail section which winds through spruce and aspen groves until you reach the veritable highway of the "M" trail. Follow to the right for ~1mile until you reach "M" trail head. <br />
You'll need to shuttle this one, or hitchhike, or ride the ~3 miles back to town or ~6 miles back to Sypes trailhead on the road.
From Bozeman, take 19th Ave. to the north until it ends at Springhill road. Follow Springhill for ~2 miles looking for Sypes Canyon Forest Service sign, turn right. Follow signs to trailhead.
