Secret de La Licorne / Geheim van de Eenhoorn

Walibi was home to a Tintin darkride, Le Temple du Soleil, from its opening year in 1975. This ride was demolished after the 1979 season and was indirectly replaced by Secret de La Licorne.

Also this Tintin dark ride was eventually closed, after the 1995 season. Some say it was due to the license expiring, but other rides centred around Tintin were kept operational until at least the year 2000. The ride sat SBNO for some years, until the park got taking over by Premier Parks (later Six Flags) in 1998, which used it for a haunted maze during the Halloween seasons.

Six Flags played around with the idea to construct a new dark ride in the building starting from at least 2001 and the Dutch company NOB was invited to come up with a concept for it. Eventually it was the American Sally Dark Rides who got to develop the new ride, which ended up being Challange of Tutankhamon, opened in 2003.
