You're right, the resort road is good to the end where the Soldier Creek TH is. Now comes the "but"! Chimney Creek road can be bad due to ruts on the uphills. The first mile past the house has always been good since the Bobbleheads use it as a trailhead in the winter. My girlfriend lived in the house just off the road. I used to be able to drive my VW Bug up to the sheep corrals later in the summer. The corrals are between the W. Fork of Corral Creek and Ear Creek. I would say that it's probably at least 5 miles to the corrals from the turn off of Hill rd. To conclude, I don't think that I would take my Suby up there in the spring. I could be wrong since I am no longer a local!
If you do go up that way, let me know how the road is. I would like to ride up to the lookout from the corrals.
