Throughout the 1970s, Rivertown saw the addition of several attractions including Kenton's Cove Keelboat Canal in 1973, which was an elevated log flume ride that operated through the 2000 season, and The Beast roller coaster in 1979. Designed internally by Kings Island, The Beast opened as the tallest, fastest, and longest roller coaster in the world, and in addition to retaining its record length, it remains one of the most popular wooden roller coasters in the annual Golden Ticket Awards from "Amusement Today". Other rides added over the years include a river rafting ride called White Water Canyon, which opened in 1985, and a heavily themed, indoor flat ride called Tomb Raider: The Ride (later renamed The Crypt), which opened in place of Kenton's Cove Keelboat Canal in 2002. The Crypt closed permanently in 2011.
