Make sure to call the bat hot line in advance to get the times that the bats are exiting from the bridge. This is an absolutely amazing sight. We walked up and sat directly under the bridge on the south side - in April the bats were exiting between 7:45 and 8:30, but call ahead and check. We parked our car halfway up S. Congress Street (on a side street) then walked the rest of the way up to the bridge. This put us in good position to get dinner at at restaurant on SoCo and then not be too far from our room. This was easily one of the high points of our trip.
