Since a lot of persons seem to be using Limestone Pk, Sheep & Piute Mtns as "warm-ups" for White Mtn, the NFS has made an informal parking lot closer to the Piute/Sheep Mtns area. Instead of parking near the Patriarch Grove, take the road towards White Mountain. When you get to the top of the first rise (White Mtn will appear off in the distance), you can turn off and park on the flat area on the EAST side of the road. Start hiking up the hill on the west and you'll first top out on Limestone Peak, can traverse to nearby Sheep Mtn, then traverse once more to Piute Mtn. A relaxing 4-5 hr hike.
