On 21 September 1994, Pat R and I climbed Hawes from the south. We drove on good dirt road 3N16 that goes from Green Valley north through Crab Flats and then NE to Big Pine Flat. About 2.8 mi NE of Crab Flats campground the road makes a hairpin turn as it crosses Holcomb Creek. 1.2 mi after (NE) of the creek crossing an old road leaves 3N16 where it makes a right turn at (957931). There are some large (3') rocks that have been placed at the start of this old road to prevent automobile use. There is space for several cars to park.
Our route was north on this old road for about 0.4 mi to a creek crossing (957936), then NE on a road/trail along the creek for about 0.2 mi, then north on a trail up a tributary for say 0.2 mi to (959942). From here a sort of road/fire break goes west up the ridge that becomes the south ridge of Hawes and ends at the shallow saddle about 100m east of the summit.
The walking was fine all the way with no brush and pretty vegetation. It took us 1.3 hrs to ascend and 1 hr to come down. The gain is 1100' and distance is about 3.5 mi round trip.
