In eastern Pennsylvania, on the eastern edge of Allentown, is the town of Bethlehem. This historic town was founded in 1741, making it one of the oldest towns in Pennsylvania. Right at home in the Lehigh Valley, cut in half by the Lehigh River, and even home to Lehigh University, Bethlehem offers visitors a rare glimpse at many points in American history. In just a short 20-minute drive, you can see old colonial buildings, Industrial-Age smokestacks, and the various modern art installments and murals. On top of that, Pennsylvania is packed with natural beauty that is sure to leave any outdoor adventurer star-struck (just look toward the mountains when you’re on Main Street, and you’ll see the giant Bethlehem star); there is never a wrong time to rent an RV in Bethlehem.
