About 69 miles (110 km). Park at roadside at Frost, WV. At Dunmore, stay right toward Green Bank, WV. Mostly flat/rolling, but one small climb before reaching US 250 near Bartow. Right on US 250 toward Monterey, VA. First and biggest climb up Tamarack Ridge (1080 feet in 3.5 miles) to the WV/VA border. Down the steep hill to Back Creek, then another climb up Lantz Mountain (500 feet in 1.6 miles). Down the hill to Hightown, then up Monterey Mountain (720 feet in 2.1 miles). Down to Monterey, VA. Right on US 220, then right on VA 84. Rolling/flat through Mill Gap, VA. One final climb (420 feet in 1.3 miles) to the WV border, then flat/downhill back to Frost. A beautiful ride! Some truck traffic between Dunmore and Bartow, but otherwise very little traffic. Road surface is good to excellent; a little rough going up Tamarack Ridge.
