Knapsack Bridge

The Knapsack Bridge, also known as Knapsack Viaduct, is one of the Blue Mountains' most impressive heritage landmarks, combining spectacular engineering with stunning natural scenery. Originally constructed in 1867 as part of the first railway crossing over the Blue Mountains, the sandstone viaduct spans Knapsack Gully on the edge of Glenbrook and stands as a remarkable example of nineteenth-century engineering achievement. Today, the restored bridge forms part of the popular Knapsack Walking Track, offering visitors the chance to walk across this historic structure while enjoying sweeping views of the surrounding bushland and escarpment.

Set within the lower Blue Mountains, the Knapsack Bridge is a favourite destination for walkers, cyclists, photographers and history enthusiasts. The easy access trail - part of the historic Lapstone Zig Zag Walk - follows part of the former railway alignment and provides a fascinating glimpse into the region's transport history, including interpretive signage that tells the story of the railway pioneers who helped open the mountains to settlement and tourism. Whether you're exploring the area on foot, enjoying a family outing, or seeking a unique heritage experience, the Knapsack Bridge offers a memorable combination of history, nature and panoramic views just a short distance from Sydney.
