Deep water

Not only deep, but Woolwich Dock is long and narrow, a chasm-like drydock overshadowed by towering sandstone walls. Eighty-five thousand cubic metres of sandstone were excavated from the site to construct the drydock, and when it opened in 1901 it was the largest in Australia. Now, there is a raised metal walkway and a keep-between-the-yellow-lines footpath forming part of the Sydney Harbour foreshore walk, so you can walk all around the channel of water, from Goat Paddock to Horse Paddock, without having to get your feet wet.
