EpicSUP sends water walkers gliding across the azure surface of Lady Bird Lake on handmade, eco-friendly stand-up paddleboards. Bipeds paddle upright on the lightweight board, taking in views of downtown Austin, verdant parks, and squirrels plotting world domination. Those who opt for the two-hour excursion can capture each wave-riding second with a high-definition camera mounted to their board. Novice riders find their sea legs during the one-hour lesson, learning the fundaments of board-side standing, steering, and square dancing.

Each EpicSUP board boasts an eco-friendly upbringing from Ecoboard Works, a company that handcrafts floaters from bio epoxy sap-based resins. All guests receive a life jacket to provide buoyancy in case of a fall or a cushy buffer in case of a hug from an overly affectionate kraken.
