Getting to Kowloon Bay by water, travellers would go ashore to the Walled City through a long, Chinese-style stone bridge. The whole structure is called the Lung Tsun Pier, unearthed in 2008 at the site of the former Kai Tak Airport.

The Kowloon City coast was originally a shallow mudflat too soft to allow medium or large boats to berth at. To accommodate passengers that came on vessels, the Lung Tsun Stone Bridge was constructed in 1875. Over 200m in length and 2m in width, the Bridge was supported by 21 pillars and paved by large flagstones. Later, as the beach silted up, a wooden extension was added in 1892, lengthening the Bridge to 300m. A checkpoint was set up
on the Bridge and boats had to pay tariff for any loading or unloading of cargos.

At a later time the authority provided traders with a public weight to facilitate delivery, and the fee paid for using it would go to Lok Sin Tong, a charity organization in Kowloon City. Since foreigners without exception got into the Walled City via the Lung Tsun Bridge, steamboats were in operation every day to carry them from and to the Hong Kong Island. Soon ferry service was offered to take them directly to Macau and Guangzhou.

Once landed, travellers would catch sight of the Lung Tsun Pavilion at the landward end of the Pier. The Kowloon Battery was on its left, and the residential quarters along the Kowloon Street on its right. The White Crane Hill and the northern wall of the City in the distance made up a fine background to this scenery.
