GPS is accurate but do not take Biggs Rd. Take the driveway at the mailboxes for 105 and 103 Chestnut Hill Rd and stay to the right to go up to 105. Driveway is steep but paved with parking and turnaround space at the top.
From Black Mountain take NC 9 south 5 miles, then right on Chestnut Hill Rd. Driveway is about 1 mile on the right.
