Located southeast of Boulder, Louisville is home to several high-tech companies that specialize in space exploration. Families gather at Steinbaugh Pavilion for summer concerts and to ice skate in the winter. Galleries, studios, restaurants and music venues occupy many of the 100-year old buildings that line streets in the downtown area. The town’s pubs are packed with personality, including Waterloo in Old Town, which offers live music, mixed drinks, beer and burgers.
