Located on Holden Lake south of Nanaimo, this forested park is popular with local residents, who mainly come here to explore the extensive trail system. The marsh area at Hemer Provincial Park is also a favourite destination for bird watchers and ornithologists. A viewing platform over the marsh, approximately 1 km from the parking lot, provides the opportunity to observe various types of ducks, Trumpeter swans, Bald eagles and turkey vultures, as well as beavers.
Approximately 11 kilometres of easy walking trails weave through the park along Holden Lake and through the marsh areas. The trails are forested, primarily with mature coastal Douglas fir, red alder and big-leaf maple. Trails are not marked but are easily identifiable and well maintained. Hemer Park provides day-use opportunities at Holden Lake, a peaceful setting for paddlers, boaters and anglers.
