Well there are a number of great walks along the Brisbane River. Walking from South Bank to Kangaroo point is great for artwork, and walking on the opposite shore takes you past many historic buildings.
Of course South Bank itself is a nice place to walk or sit and relax.
For a more solitary walk you can go from GoMA in South Brisbane towards West End. This quiet area is set to be transformed, but we are not sure how much public access or parks will be left.
Cyclists and joggers follow the opposite bank as it tends to give you a fairly straight run with few dawdlers.
You can cross over quite a few of The Brisbane River Bridges, but the best one is the unusual Kurilpa foot bridge, which has also won international design awards. It leads to the Gallery of Modern Art (GOMA) which is a pleasant place to wander around and my pick of the Brisbane River.
There are many Riverfront Cafes along the Brisbane River which are all recommended due to their excellent views. You can catch the Citycat to visit them all.
