Cangai Broadwater Reserve is a free riverside campground on the Mann River in northern New South Wales, situated upstream of Copmanhurst in the upper Clarence Valley.

It forms part of a network of Crown reserves designed to support the Clarence Canoe Trail, with its prime attractions being direct river access, a scenic natural setting, and opportunities for water-based recreation.

From Grafton, head west on the Gwydir Highway for approximately 69 km, turn right onto Cangai Bridge Road, then left onto Hanging Rock Road to reach the reserve.

Visitors can enjoy fishing, swimming, kayaking, tubing, and picnicking along the river, with several national parks also accessible in the surrounding area.
