Phifer Creek Road climbs sharply from the Middle Fork of the Boise River to Trinity Ridge Road. It is a one-lane gravel and rock road suitable for any vehicle with moderately high clearance. Although in generally good shape, there are sections with rocks and washouts. There are many tight switchbacks with quite steep sections right in the turn. Most of the road is in a timber tunnel that restricts the big views; however, there are enough open areas where the views open up to keep the road interesting. During fire season, the views can be blocked by smoke and haze.
No campgrounds are along Phifer Creek Road, but numerous opportunities exist for dispersed camping.
