Congress Avenue Bat Bridge
You end where you started, but the bridge is a completely different experience now. Time this final leg so you arrive 20 to 30 minutes before sunset between roughly March and early November, because that is when the bats stream out from under the deck in a dark ribbon over Lady Bird Lake. It is free, it is open access, and on a good summer evening the emergence lasts up to 45 minutes. Best free vantage: the lawn at the Statesman Bat Observation Center on the southeast bank, where you look up at the underside of the bridge against the dusk sky rather than peering straight down from the rail. Get there early; the spot fills up. Call the Bat Hotline or check the city's bat info before you commit, since cold fronts and rain can keep them in. If you miss the emergence, the bridge at night still gives you the skyline reflected on the water, which is a fine last photo to close the loop.
