Visit this 300-year-old (60' tall) white oak tree, the second largest on the entire Appalachian Trail.
You can park your car at the small gravel lot where VA-42 and Rt. 629 intersect. Starting from the Appalachian Trail crossing at VA-42, head north on the AT, which winds through some grass meadows. After about 0.8 miles into the hike you will cross Rt. 630 (Northside Road) on a bridge over Sinking Creek. The trail continues to the right side of the creek.
From here it is a short 0.5 miles to the Keffer Oak. You won't miss this tree. It is 300 years old, with a circumference of 18-20 feet. There is a cleared area here with some logs to sit on and rest under the tree.
Once finished, walk the 1.3 miles back to your car by retracing your steps south on the AT.
*Note: For a shorter hike, park at the Rt. 630 bridge where the AT crosses Sinking Creek and head 0.5 miles north on the AT to see the Keffer Oak.
