Tuen Mun sits at Hong Kong's northwestern boundary with the Pearl River estuary and the Chinese mainland. The ferry pier in its southern district is not the only way to leave, but it is the most elemental: you stand at the edge of the land and board a vessel. The pier itself is managed as part of a vertical transportation hub — Light Rail above, buses at street level, ferry below. The Ocean Walk shopping centre rises above the transit infrastructure, and the Pierhead Garden residential towers above that. This layering of uses — retail, transit, residential — compressed into a single development footprint is characteristic of how Hong Kong builds in constrained space. The pier is at the bottom of the stack, literally and historically. Everything else came after.

Over the years, Tuen Mun Ferry Pier has served as a launching point for some of the more ambitious cross-border connections in the western New Territories. Ferry service to Lantau Island — reaching Tung Chung, Tai O, and Sha Lo Wan — continues, operated by Fortune Ferry. The Macau connection has a more complicated history. Plans for a Tuen Mun–Macau route surfaced in December 2003, were rejected by Macau authorities in 2006 on technical and safety grounds, then revived, licensed in 2011, and finally inaugurated by TurboJet on 28 January 2016. The COVID-19 pandemic suspended cross-border services in January 2020, and by June 2021 TurboJet had formally returned the terminal to the Hong Kong government, ending the Macau connection. Ferry service to Zhuhai's Jiuzhou Port opened in November 2006 and closed in October 2007. The routes came and went; the pier remained.

The Tuen Mun Ferry Pier stop is the southern terminus of Hong Kong's MTR Light Rail network — the surface-running rail system that serves Tuen Mun and Yuen Long. Seven platforms branch from the terminus, supporting six distinct Light Rail routes. What made this stop unusual among transit interchanges was the customer services centre: it was once the only Light Rail facility that sold Intercity Through Train tickets from Kowloon's Hung Hom station to mainland China destinations including Guangzhou, Dongguan, Shanghai, and Beijing. The Intercity Through Train service was permanently discontinued in July 2024, a casualty of the pandemic and competition from the Guangzhou-Shenzhen-Hong Kong high-speed railway. The pier and the rail terminus remain physically adjacent, a reminder that this corner of Tuen Mun once functioned as an entry point to a rail network reaching hundreds of kilometres into the mainland. The geography of the Pearl River Delta compresses distances that would seem impossible elsewhere.

The original Tuen Mun Transport Complex served as the interchange between ferries and buses before reclamation moved the pier location and the MTR absorbed the volume. The pier adapted. The Ocean Walk shopping centre — originally called Pierhead Plaza, renamed in 2006 after a competition among KCR Corporation staff drew 80 entries — provides the commercial layer above the transit hub. Pierhead Garden, the residential estate above that, sits on the second-floor balcony of the mall. This vertical community grew directly from the pier's infrastructure, each layer dependent on the one below. The pier is no longer the emergency escape valve it was during the Tuen Mun Road congestion era. It is something more permanent: a working part of the daily fabric of a city built at the water's edge.
