#42 of 319 mountain bike trails in Idaho

#3,430 in the world

Nice optional route in the Boise Foothills that connects Military Reserve to 8th street and upper Hulls Gulch. You're only on the very lower end of Three Bears #26 for about 1 mile where it is an old road, then you turn off on Trail #5, which is a steep ridgeline old two-track. Fat Tire is a nice bench cut singletrack, and Trail #4 is steep as well and shared with OHVs but a good downhill run.
