Tourism is very important to Western Maryland. There is a thriving tourist industry, and has been noted as having "potential for significant growth." Western Maryland has a number of sites with significance for military history, particularly the Civil War. In 1862, Washington County was home to one of the Civil War's bloodiest single-day battles at
Antietam National Battlefield. Western Maryland, particularly Cumberland, is also home to transportation themed tourism. The
Downtown Cumberland Historic District is a National Register Historic District, and Cumberland's
Western Maryland Railway Station is a popular site. Garrett County is also well known for its numerous state parks and outdoor activities. Places such as
Deep Creek Lake in Garrett County are frequented by many visitors every year. The largest lake in Western Maryland is
Deep Creek Lake in Garrett County. The 4,000 acre body of water is owned by the State of Maryland and is man made. Construction began in 1920 and the lake was filled by 1929. It was originally made to power a small scale hydroelectric plant, but was eventually turned into a tourist destination. The lake is currently managed for boating and fishing, although it still provides some water to generate electricity. The
Deep Creek Lake State Park offers fishing piers, beach and swim area, covered pavilions, and opportunities for camping. Maryland's only ski resort,
Wisp Ski Resort, is located on a 172 acre property next to Deep Creek Lake. Hosting a year-round mountain coaster and cross country skiing and snowmobiling in the winter, it is a major tourist attraction in the region. ==Sports==
