The Blue route is an 80 minute hop-on-hop-off tour of the city that starts at the Stadpark and heads out East out of the city along the side of the Danube Canal, before heading over to the Prater and Messe areas of the city.
From there it heads over the Danube itself and stops at the Danube Tower and the UN area before heading back into town.
