The arbour walk.

The Grand Arbour at South Bank is 443 magenta-flowering bougainvillea trained along curved steel pergolas for almost exactly one kilometer down the Brisbane River side of the parklands. It was built for Expo 88 and rebuilt in 2016; the canopy is dense, the bloom runs roughly October to May, and at midday in summer it is the only continuous shaded run in the central city. The picks below treat it as the spine and pull in the rainforest walk, the Nepalese Pagoda’s small canopy, and the perimeter of Streets Beach as auxiliary shade. The shade scores are honest: 88 along the arbour itself, lower at the gaps where the bougainvillea has been pruned hard.
