Anti-grav sailing

From Memory Alpha, the free Star Trek reference

Anti-grav sailing was a recreational activity which used vehicles equipped with Anti-gravs to travel through scenic terrain.

Jadzia Dax once invited Kira Nerys to go anti-grav sailing in a holosuite. The holoprogram would have taken place on the colony of New Mecca, and featured the Great Erg. Kira was interrupted, however, before she could make use of the program. (DS9: "Second Skin")
