Bau is a historic gold-mining located approximately 29 kilometres from Batu Kawa. The town has a rich mining heritage dating back to the 1800s, when the Hakka Chinese community began gold mining activities centred around Pangkalan Tebang. Local historical records and oral traditions suggest that the first Chinese settlement in Bau was established around 1830, reflecting the town’s early role as a mining hub.

Today, Bau is developing into a tourism and lifestyle destination. Roxy Tasik Biru Resort is one of the key attractions, offering recreational facilities such as a floating bridge, fountain, chalet accommodation, café, and boat ride services.
Nature tourism is also prominent in the district, with notable attractions including Fairy Cave and Wind Cave, both of which are popular for their unique limestone formations and cave exploration experiences.

In addition, Bau District is expanding its commercial and community infrastructure. New developments include the ROXY Tasik Biru Resort City Shophouse, as well as cultural and sports facilities such as the Bidayuh Cultural Centre (Jambusan) and Bau Sports Arena, supporting the district’s growth in tourism, culture, and community activities.
