The #210 trail adds an 8-mile round trip if you drop in from the top at the Ashley Mtn. Trail #310
. As the name might suggest, lupine flowers are abundant in the spring on this trail.
The bottom 3-miles or so offers fun singletrack that is 100% rideable down and then back up. I normally stop at Lupine Lake for a swim and at the bottom, if you walk up the canyon a bit, there is a nice waterfall.
The upper 1-mile of trail, however, is in very poor shape from lack of maintenance or design in addition to a large amount of motorcycle use. Some of it is rideable, but for the most part, it's a push. This section has deep troughs, can be quite "choosy," especially in the root sections.
