The C.F. Martin guitar factory is located in Nazareth, Pennsylvania. They offer tours for a modest cost of $5/pp but the tour groups sell out quickly. Advanced online reservations are imperative, especially for popular summer months.
The guided tours are groups of 12 led through the working factory and meet workers. The tour ends in the Picking Room where visitors can try out guitars on the wall and order them at a modest discount.
You can visit the Museum inside the factory without a reservation. The Museum contains guitars and instruments from the breadth of company history, from C.F. Martin’s first guitars to its 1-millionth guitar.
