The Banana Splits Adventure Hour was an hour-long, packaged television program that featured both live action and animated segments.

The show's live-action segments Danger Island, a cliffhanger serial, as well as the short-lived The Micro Ventures ran alongside with the animated segments, The Arabian Knights and The Three Musketeers.

Each show represented a meeting of the "Banana Splits Club," and the wraparounds featured the adventures of the club members, who doubled as a musical quartet, meant to be reminiscent of The Beatles and The Monkees.

The main characters were Fleegle, a beagle; Bingo, a gorilla; Drooper, a lion, and Snorky (called "Snork" in the theme song lyrics), an elephant. Fleegle would assume the role as leader of the Banana Splits and preside at club meetings. The characters were played by actors in fleecy costumes similar to later Sid and Marty Krofft series such as H.R. Pufnstuf.

The Splits' segments, including songs-of-the-week and comedy skits, served as wraparounds for a number of individual segments. In the second season, The Three Musketeers segments were replaced with repeats of The Hillbilly Bears, a cartoon segment that previously appeared on The Atom Ant Show (1965-1968).

For the first season, some of the live action segments (specifically those used during the musical segments) were shot at Six Flags Over Texas, an amusement park located in Arlington, Texas.

For the second season, filming took place at the Coney Island amusement park, located in Cincinnati, Ohio. In many episodes, the Banana Splits would be seen riding on the Runaway Mine Train rollercoasters, Log Flumes, Bumper Cars, Merry-Go-Rounds, and many other rides at Six Flags.

Contrary to popular misconception, the amusement park scenes in the original series were not filmed at Kings Island, also in Cincinnati, Ohio, which did not open until 1972. (Filming for The Banana Splits Adventure Hour wrapped in 1969). However, some of the rides seen in the series eventually were relocated to Kings Island and the live-action scenes in the 1972 production The Banana Splits In Hocus Pocus Park were indeed filmed at Kings Island in Cincinnati.

All of the live-action material filmed for the first season of The Banana Splits Adventure Hour (including the Banana Splits and Danger Island sequences) was directed by future Superman director Richard Donner.
