Mountain Biking Three Bears #26, Trail #5, Fat Tire #42, Trail #4

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.

    Literally I dont know how this is a green. Maybe for Fat Tire, maybe. Three Bears is the coolest trail, with a demon of a climb and a super steep downhill.

    Very nicely put together network of trails. Nothing too difficult, very smooth and flowy.
