Batcave entrance

[Julian]

A vehicle entrance to a facility that is obscure and infrequently used. Often the only people who know of this entrance are the employees who work there. Golf courses, farms, industrial parks, sports facilities and outdoor museums often have [batcave] entrances. Management often frowns on use of this entrance. This term is inspired by the Batman TV series from the 1960s. In that program, the entrance [to the Batcave] was down a little-used [dirt road] that was blocked at one end by a fake wooden barrier.
