Turn Austin into a giant game board on an interactive scavenger hunt that combines the fun of the reality series, "Amazing Race" with a 3-hour sightseeing tour. Using your smartphone, make your way among well-known and overlooked gems, solving clues and completing challenges while learning the local history. Set off near Congress Avenue Bridge – known as the Bat Bridge for the bats that come out nightly – and follow the trails that travel both sides of Lady Bird Lake to experience the wild side of the city. Encounter famous sculptures, tributes to musicians, hidden art, and grand vistas of the skyline along the way. Start when you want and determine your own pace, stop for lunch or take a stroll on one of the shaded trails. Great value for people on a budget, the scavenger hunt covers dozens of points of interest, including the urban park of Auditorium Shores, the Long Center for the Performing Arts and Shoal Beach.
