Indian Park is located on the north-western side of Montoursville and is parallel to Interstate 180/U.S. Route 220. It serves as a large recreational park with several miles of hiking and biking trails, numerous softball fields, picnic areas and pavilions and fishing ponds. Indian Park was a trolley park during the late 19th century and early 20th century. Visitors from Williamsport would board the trolley in downtown Williamsport and ride to Indian Park to spend a day of recreation along the banks of Loyalsock Creek. The park was home to one of the largest and longest roller coasters on the East Coast of the United States. The park also featured over 20 acres (81,000 m2) of ponds, a theatre, and a merry-go-round. The amusement park was ultimately closed in 1924 due in large part to the rising and continued cost of reconstructing the park following the nearly yearly floods on Loyalsock Creek.
