From Philadelphia, take the Schuylkill Expressway (I–76) west to the Pennsylvania Turnpike. Lancaster County sights are accessible from exits 20, 21, and 22. Another option is to follow U.S. 30 west from Philadelphia, but be prepared for a lot of traffic. It's about 65 mi to the Pennsylvania Dutch Country.
A car is the easiest way to explore the many sights in the area; it also lets you get off the main roads and into the countryside. Lancaster County's main arteries are U.S. 30 (also known as the Lincoln Highway) and Route 340 (also called Old Philadelphia Pike). Some pleasant back roads can be found between routes 23 and 340. Vintage Road is a country road running north over U.S. 30 and then along Route 772 west to Intercourse. You get a look at some of the farms in the area and also see Amish schoolhouses, stores, and the Amish themselves. Remember that you must slow down for horse-drawn buggies when you're driving on country roads.
