From March through October, Capital Cruises ply Lady Bird Lake with electric-powered boats heading out on a number of popular tours. The bat cruises are especially big in summer, when warm nights are perfect for enjoyable, educational hour-long excursions. The high point is seeing thousands of bats stream out from under their Congress Avenue Bridge roost. Afternoon sightseeing tours are a nice way to while away an hour on the weekend. Dinner and lunch cruises are offered, with catering from the Hyatt Regency kitchen. Rates depend on the size of your group (min. 2 people) and the meals you choose.
