I recently hopped aboard a Lonestar Riverboat Cruise to check out the bats and found the price very reasonable at $10 for adults and $7 for kids. Before the big event we floated between the two bridges - Congress St. and First Street while our ship's captain regaled us with amusing facts about Austin's expanding skyline.
If you're planning to take the bat cruise I highly recommend bringing along a hat as the bats are numerous and not particularly well potty-trained, if you know what I mean. But it's a fun way to spend an evening with nature, if you're into that sort of thing.
