Contoocook River Amusement Park was a trolley park in Penacook, New Hampshire. The park was developed along the south bank of the Contoocook River. For twenty cents in 1893, and up until the 1920s, one could ride 7 miles (11 km) on the trolley from downtown Concord to Penacook to enjoy free entertainment, fireworks, swimming, dancing at a large pavilion, boating, roller-skating, bowling, and even a steamboat ride up the Contoocook River.
