Black Diamond, Steel roller coaster at Knoebels Amusement Resort in Elysburg, Pennsylvania.
Black Diamond is a steel roller coaster at Knoebels Amusement Resort featuring a completely enclosed track with a maximum height of about 35 feet. It uses two-car trains seating four riders each and operates at a moderate speed of 12 mph through its indoor course.
The ride was built in 1960 as Golden Nugget at Hunt's Pier in Wildwood, New Jersey, operating as an outdoor coaster for decades. It was relocated to Knoebels Amusement Resort in Pennsylvania in 2011, where it was renamed and given its distinctive indoor track.
The mining theme connects to Pennsylvania's industrial past as a major coal and mineral extraction region. Riders pass through themed mine scenes that make this heritage tangible during the indoor journey.
Riders must be at least 42 inches (107 cm) tall to board, and the complete journey takes about three minutes. Since the entire track runs indoors, this experience is unaffected by weather and available year-round.
The ride was renamed from Golden Nugget to Black Diamond when relocated, matching its new mining theme that references coal rather than precious metals. This name change marked a fresh identity that better suited its Pennsylvania home and indoor mine setting.
