Go to Google maps with the hybrid map as the map you will be using.
*Zoom in on North East Price
*Follow Bird Rd North. It will merge with the Keilworth-Price Backroad/Oil Well Rd
*Follow the Kenilworth-Price Backroad/Oil Well Rd North
*Turn East on the Alrad Canyon Rd before you reach Kenilworth
*About 500 ft past the intersection with the Cardnial Wash Rd while you are still driving on the Alrad Canyon Rd there are two ravines branching off to the north of the road. The ravine further west is Diff-Hanger. The ravine further east is Grimlin.
*If you look south of these two ravines you will notice a longer ravine that follows along the Cardinal Wash Rd. This ravine is lower Diff-Hanger. You access the trail from the Cardinal Wash Rd.
