Lakemont Park, located in Altoona, Pennsylvania, houses the world's oldest-surviving roller coaster, the Leap-The-Dips. Leap-The-Dips is a wooden roller coaster. Constructed in 1902 by the Federal Construction Company and designed by E. Joy Morris, it is the oldest operating roller coaster in the world and believed to be the last surviving side friction roller coaster of the figure-eight variety.

Leap-the-Dips operated continuously until 1985, when it closed after falling into disrepair. A fund-raising campaign led to its restoration, with refurbishment efforts beginning in 1997 and ending with a grand-reopening in 1999.

On June 19, 1996, the roller coaster was added to the list of National Historic Landmarks by the National Park Service. The park opened in 1894 as a trolley park and became an amusement park in the summer of 1899. It is one of only thirteen trolley parks still operating, and the 8th oldest amusement park in the United States.

The park was owned by the Boyer Candy Company from May 23, 1986 until July 1, 1988, when it was called Boyertown USA. The park was closed from 2017-2018, but re-opened in summer 2019.
