Bethlehem to Trumbauersville on mostly quieter roads, some stone houses + farms, by way of Saucon Valley + Vera Cruz. Intended to form a loop with route [LVa2a] (or shorter and less hilly with [BPhB7] or [BPhB7a] and [BPhB8]). Hilly, though it avoids the steepest. For more info + connections see www.roberts-1.com/x/pa - routeID [LVa2b]. Points have been tweaked and tested for GPS navigation in the direction of route given. We've ridden this route many times, but have not checked it since 2009. by NJwandr
