The Whanganui Regional Museum, adjacent to the Sarjeant Gallery on the hill above Queens Park, has an extensive and well-presented collection of natural and human history for the region. The Māori section is particularly strong, with taonga (treasures) spanning several centuries of Whanganui River iwi history, including the famous carved waka taua and remarkable 19th-century textiles.
The natural history galleries cover the geology, flora, and fauna of the Whanganui region. The museum also has a significant archive of early photographs of the river and its communities. Admission is by donation.
