The tour begins at the Cardiff Bay Wetland Reserve, which covers around 8 hectares of land to the north of the bay. This site was created after the removal of the Taff-Ely Site of Special Scientific Interest, making it a key part of the area’s redevelopment. Visitors walk through this peaceful natural space, gaining a sense of Cardiff Bay’s ecological importance and its adaptation from industrial to natural environments. Entry is free, and the stop takes roughly 10 minutes.
From here, the route naturally leads to the St Davids hotel, a prominent landmark visible from most parts of the bay. Built as part of the area’s regeneration, the hotel exemplifies Cardiff Bay’s modern development and offers a familiar point of reference for navigation.
Moving towards Mount Stuart Graving Docks, visitors see the old dockyard infrastructure built by the Marquesses of Bute. This site offers insight into Cardiff Bay’s industrial past as a major shipping and dockland hub. The docks are free to explore, and the stop lasts about 5 minutes.
Close by, Techniquest is highlighted as the UK’s longest-established science discovery centre, since its founding in 1986. This attraction provides a hands-on science experience, making it an appealing stop for families and curious minds.

Mermaid Quay is a mixed land-use development opened in 1999, featuring over 30 restaurants, bars, and cafes. Visitors enjoy a lively atmosphere with options for dining, shopping, and entertainment. The boardwalk beneath Mermaid Quay adds to the waterfront ambiance, and on the western side, Ian’s Shrine serves as a memorial to a man who never existed, offering a quirky piece of local lore.

A major highlight of the tour is Roald Dahl Plass, once the dockyard entrance where ships passed through beneath the current footbridge. This open space has become a cultural hub, hosting events and public gatherings.
At the end of Roald Dahl Plass, visitors find the Grade I listed Pierhead Building, which served as the headquarters of the Cardiff Railway Company. Its distinctive architecture makes it a visual standout. Nearby, the Wales Millennium Centre dominates as the national arts centre of Wales, home to Welsh National Opera and BBC Wales.

The Cardiff Bay Barrage is a central feature of the tour, constructed to maintain the water level in the bay. Visitors can admire the 20 km of pipes and 6,000 air diffusers that aerate the inland waterway, ensuring a stable environment for the bay’s ecosystem.
An exhibition and viewing platform at the barrage allows visitors to observe the locks, sluice gates, and fish pass.

The area offers interesting views of the Penarth side, with notable buildings like the Marine Building and Old Custom House.
The exhibition area at the barrage features permanent displays, making it an educational stop. Around the site, visitors can enjoy mini wildflower meadows, adding a touch of nature to this engineering marvel.

Participants receive 3 weeks of unlimited access to the tour via the app, which includes maps, GPS routes, and detailed stop information.
