Walnut Creeek (Albemarle Cty. park south of C'ville), O-Hill (Observatory Hill between Hwy. 29 and the grounds of UVA in C'ville), Chandler Mtn. @ Liberty University in Lynchburg, Peaks View Park in Lynchburg, Carvins Cove in Roanoke - a bit far but well worth the drive.
A lot has been written on these trails in these forums. Do some searching and enjoy the ride!
