Idlewild and Soak Zone, commonly known as Idlewild Park or simply Idlewild, is an amusement park in the Laurel Highlands near Ligonier, Pennsylvania, United States, about 50 miles (80 km) east of Pittsburgh, along US Route 30. Founded in 1878 as a campground along the Ligonier Valley Railroad by Thomas Mellon, Idlewild is the oldest amusement park in Pennsylvania and the third oldest operating amusement park in the United States behind Lake Compounce and Cedar Point. The park has won several awards, including from industry publication Amusement Today as the best children's park in the world. The prominent Mellon family established the park in 1878, and it remained family-owned for over 100 years. It expanded greatly throughout the first half of the 20th century, adding rides including a Philadelphia Toboggan Company Rollo Coaster in 1938, one of the company's earliest. The park is home to the Ligonier Highland Games, a Scottish athletic and cultural festival that has annually drawn over 10,000 spectators. In 1983, the park was purchased by Kennywood Entertainment Company, which oversaw additional expansion, including an attraction designed and voiced by Fred Rogers based on his television show Mister Rogers' Neighborhood. Since 2008, the park, as well as others formerly under Kennywood Entertainment, have been owned by Spanish company Parques Reunidos and operated by their American subsidiary Palace Entertainment.

Rollo Coaster is a wooden roller coaster located at Idlewild and Soak Zone near Ligonier, Pennsylvania, United States of America. It was built in 1938 by the leading roller coaster designer and builder of that era, Philadelphia Toboggan Company. It was Idlewild's first and only roller coaster for decades until the larger Wild Mouse coaster was erected in 1993. The coaster closed in 2016, amidst safety concerns, but was reopened for the 2018 Operation Season. Built over a hillside at Idlewild Park, the Rollo Coaster is an out and back format. It uses skid brakes operated manually with a lever. The train consists of 4 cars that have 2 rows in 1 car and 1 row in the others. Each row has 2 seats. It was popular with coaster enthusiasts due to its lack of restraints except for a grab bar, until 2018. It is located next to the Carousel and Flying Aces. While the Rollo Coaster features only small hills, it uses topography to its advantage. Built over steep terrain, the ride features many tight twists and turns which create a rough ride and a sense of much greater speed. This coaster was the inspiration for Boulder Dash, a similar but much larger coaster at Lake Compounce. The Rollo Coaster was an ACE Coaster Classic.

Wild Mouse is the name of a roller coaster at Idlewild and Soak Zone in Ligonier, Pennsylvania. It is the one of two coasters in the park, along with the small classic wooden Rollo Coaster, and its only steel roller coaster.
