Tour guides Stacy and Taylor Smith— along with their intrepid dog Thor—teach students to glide with grace as they lead standup paddle boarding tours over the placid waters of Lady Bird Lake. Sunset tours cross under the Congress Avenue Bridge during its renowned nightly bat exodus when the sky is streaked with shades of melty sorbets. The Barge tour ropes together paddleboards as groups of paddlers drift over waters, pausing to play on rope swings, and sipping on BYOB libations bolstered by complimentary mojito or margarita mix on the tour’s escort barge. Alternatively, the Basics tour proffers a two- to three-hour lesson in the fundamentals of paddleboarding, including kneeling, standing, paddling, and using paddles to stroke the whiskers of passing catfish. Depending on the body's position, core and arm muscles can feel a workout burn or jellyfish-like state of relaxation.
