This brightly coloured circular walkway is supported by what look like metal chopsticks, lifting it 18m above the water filling an abandoned brickworks. Three billion bricks were made here between 1911 and 1988. Built into the loop are multimedia exhibits about the brick workers and their amphibious replacements, including the endangered green and golden bell frog.
