Wellstead Heritage Museum preserves four generations of the Wellstead family's homestead buildings and regional pioneer artefacts on Peppermint Grove Farm, about 3 km south of Bremer Bay. The site includes restored cottages, farm sheds and a small museum café.
Exhibits feature family photographs, household tools, clothing, coins, gramophones and vintage vehicles that illustrate settler life in the Bremer Bay district. The property is heritage‑listed and often included in local visitor trails and events.
