Mine Falls and Lincoln Park is an island of 325 acres of forest, river, and wetlands surrounded by the city of Nashua. Mine Falls Park was purchased by the city of Nashua in 1969 to be used as a recreational oasis. The park offers some great scenery for a quiet ride, stroll or ski through the mixed deciduous and White Pine forest. Mines Falls is the perfect place to learn how to mountain bike. The park offers a variety of trails that vary from paved double track to rooty single track. Even the most experienced rider can have fun on the parkâ€™s high speed twisting single track. The map shows only the double track, because if we included the single track it would be difficult to follow. The single track goes to and from the double track in many spots. There are about 8 miles of trails at Mines Falls Park.
