Janaran Falls was a waterfall on the planet Betazed.
It was one of William T. Riker's and Deanna Troi's (and Thomas Riker's) favorite views on Betazed. (TNG: "Second Chances")
Thomas Riker once made a carving of it in metal to give as a gift to Deanna Troi using nothing but a phaser. (TNG: "Second Chances")
