Altberg Wetland Nature Reserve

The 41-hectare reserve is nestled in a gently rolling plain.

From the southwest end of South Bay on Balsam Lake, a large wetland complex spreads up the valleys of two creeks. This mosaic of swamp forest and marsh forms a Provincially Significant Wetland, a part of which is protected within the Altberg Wetland Nature Reserve. Rudolf Altberg donated the property to Ontario Nature as a wildlife sanctuary.

The 41-hectare (102-acre) reserve is nestled in a gently rolling plain, just south and west of the Kawartha Lakes and the Trent Canal system. Large areas of swamp forest and open marsh are found on the reserve.

In 2007, the Kawartha Field Naturalists became the official stewards of the reserve.

No boardwalks or formal trails have been developed on the reserve. To protect this rare habitat, this property does not have a marked trail system and is not open to members of the public.
