Knoebels Amusement Resort (/kəˈnoʊbəlz/) is a family-owned and operated amusement park, picnic grove, and campground in Elysburg, Pennsylvania. Opened in 1926, it is the United States's largest free-admission park. The park has more than 60 rides including three wooden roller coasters, three steel roller coasters, a 1913 carousel, and two haunted house dark rides.

The amusement park is owned and operated by the Knoebel (pronounced kuh-NO-bel) family. The park's name has traditionally been spelled "Knoebels" without the apostrophe, and appears that way on all official park advertising and correspondence.

The park and its rides have won awards from organizations such as Amusement Today, American Coaster Enthusiasts (ACE), and the International Association of Amusement Parks and Attractions. In 2014, Travel Channel rated Knoebels one of their Top 10 Family Friendly Amusement Parks in the United States.^[1]

Knoebels is located in a small wooded valley in central Pennsylvania. In 1829, a local man by the name of Henry Knoebel purchased the land for $931. The valley, originally known as "Peggy's Farm", was used as farming land until the early 1900s, when a creek-fed swimming hole was introduced. Knoebel turned the property into a popular picnic destination, attracting Sunday travelers and horse-drawn hayride wagons. Soft drinks, ice cream, and snacks were sold to visitors. As the popularity of "Knoebels Grove" grew, Knoebel leased plots of land along the creeks for use as summer cottage sites. Some of these privately owned cottages, as well as cottages Knoebel built and rented, still exist on the property today.

In 1926, Knoebel added a restaurant, a steam-powered Philadelphia Toboggan Company (PTC) carousel, and a few simple games to his grove, marking the beginning of Knoebels Amusement Park. On July 4, 1926, he opened a large concrete swimming pool on the site of the old swimming hole. Featuring a filtration system that provided clean water instead of muddy creek water, the pool was named "The Crystal Pool". Since then, the park has developed around the pool, adding over 50 rides, assorted games, concession stands, and other attractions. A campground with six sites opened behind the amusement park in 1962, and as of 2004, the campground covered 160 acres (65 ha) with 500 sites.^[2]

On June 22, 1972, both South Branch Roaring Creek and Mugser Run, creeks that run through Knoebels, rose 6 feet (1.8 m) over their banks, swollen with heavy rains from Hurricane Agnes. The flood destroyed six cottages and damaged many other buildings, including 24 of the park's 25 rides, as well as the roller rink. The roller rink building was re-floored and used as a skating rink until the mid-1980s, when it was converted into the "Roaring Creek Saloon", which now contains a concession stand, an arcade, the XD Theater, and performances. A new building constructed after the flood became the Haunted Mansion dark ride, which opened in 1973. The ride has been recognized as one of America's best dark rides by organizations such as Dark Ride and Funhouse Enthusiasts (DAFE) and the National Amusement Park Historical Association.^[3]

The park again suffered major flooding in 1975, 1996, 2004, 2006, and 2011. Each caused substantial damage, but the 1975 and 1996 floods occurred during the off-season. Although the January 1996 flood left substantial damage, the worst occurred after the waters receded, when everything froze, making cleanup and repair throughout the amusement park difficult. The September 2004 flood, caused by the remnants of Hurricane Ivan, was only a half-day affair, and the amusement park partially reopened by mid-afternoon.

On June 28, 2006, another large flood struck Knoebels. About 90 percent of the amusement park was underwater just prior to the July 4th weekend. As the waters began to recede, 60 percent of the park's attractions were reopened within two days, and 90 percent within four days. Because over 100 tons of mud had to be dug out of the Crystal Pool, it was closed for 10 days. The last ride to return to operation was the Kiddie Panther Cars, whose repairs took almost three weeks.

In 2008, the park’s dark ride was the subject of a one-hour documentary, "Laff In The Dark’s Behind The Scenes At Knoebel’s Haunted House".^{[citation needed]}

On September 7, 2011, Knoebels experienced another flood, this time caused by Tropical Storm Lee. Water levels neared those of the flood of 1972, and damages exceeded that flood. The majority of the park reopened the following weekend, having missed only two days of operation.

For the 2013 season, Knoebels added StratosFear, the park's tallest ride at 148 feet (45 m). In 2015, a new roller coaster opened named Impulse, which replaced two former rides, the bumper boats and boat tag.

On July 23, 2018, Knoebels was flooded when a creek overflowed and flooded the park.^[4] About 150 employees aided in cleaning up the park. The park then flooded again on July 25, 2018. The park reopened on July 27, 2018.

In 2023, the Pennsylvania Trolley Museum acquired a trolley that had been converted into a cottage at Knoebels.^[5]

The park offers free admission, free parking, and free entertainment. Visitors are able to ride the park's attractions by purchasing either pay-one-price, all-day/unlimited-access wristbands (which are not usually available on weekends, except near the beginning and end of each season), limited-access hand stamps, or books of tickets, with hand stamp costs varying depending on the height of the rider. Knoebels has several hand stamp options, such as "Sundown Plan" and "Bargain Nights", when the park offers discounts on regular ride passes. Knoebels all-day passes do not include the Haunted Mansion or the Crystal Pool, which are additional fees.^[6]

In 1999, an attorney representing two girls who sustained injuries while riding Speed Slide discovered 15 injuries had been reported to the Pennsylvania Department of Agriculture's Bureau of Ride and Measurement Standards in recent years. Both girls underwent emergency surgery. The park was charged with negligence, failure to monitor the amount of force of the water and its effect on riders, failure to fix defects, and failure to provide adequate warnings to riders. Both of the plaintiffs fully recovered.^[33]
