Ontario Provincial Parks

Mattagami River Beach & Aeolian Deposit Provincial Park is located near Smoky Falls, Ontario, and protects a distinctive section of the Mattagami River shoreline shaped by both fluvial and wind-driven processes. The park is classified as a non-operating natural environment provincial park and was established to conserve rare aeolian (wind-formed) sand deposits and associated riverine habitats within northern Ontario’s boreal region.

The landscape includes sandy river beaches, stabilized dune features, and adjacent forest and wetland systems influenced by seasonal water levels and prevailing winds. These landforms provide insight into post-glacial sediment movement and contribute to habitat diversity along the river corridor. The Mattagami River supports aquatic ecosystems typical of large northern rivers, while the surrounding shorelands provide habitat for birds, mammals, and other species adapted to low-disturbance environments.

There are no developed facilities, marked trails, or designated campsites within the park. Access is generally by water, and use is intended to be low impact and self-sufficient. Activities associated with the park are limited to informal exploration, paddling, angling, and wildlife observation where consistent with conservation objectives.

The park’s primary purpose is the protection of uncommon geological features and the maintenance of natural river shoreline processes. Its value lies in preserving a rare combination of wind- and water-shaped landscapes within a largely undeveloped northern setting.

Facilities & Recreation

Mattagami River Beach & Aeolian Deposit Provincial Park is a non-operating, backcountry park created to protect rare riverine beach and dune formations along the Mattagami River. With no staffed facilities or developed infrastructure, the park is intended for self-sufficient visitors who are comfortable navigating undeveloped landscapes and minimizing their impact on sensitive natural features.

Water-based travel is the primary way to experience the park. Canoeing and kayaking offer a quiet and immersive way to explore the calm stretches of the Mattagami River, while small boats may also be used where conditions allow. Access points are informal, and visitors should be prepared for natural shorelines without docks or launches.

Fishing is permitted in the Mattagami River, where anglers may encounter northern pike, walleye, and yellow perch. Swimming is also possible along the river’s sandy beaches, which are a defining feature of the park. These natural shoreline areas provide refreshing access to the water, though there are no designated swimming zones or safety services.

The park supports low-impact day use for activities such as paddling, fishing, wildlife viewing, and exploring the sandy riverbanks and adjacent forest. There are no picnic facilities, washrooms, or treated drinking water, so visitors must bring all necessary supplies and plan to pack out everything they bring in.

Backcountry camping is permitted at natural, undeveloped sites along the riverbanks and within suitable clearings near the dune areas. Pets are welcome but must be kept under control to protect wildlife and the park’s fragile aeolian deposits. In winter, experienced backcountry users may access the area for snowshoeing or winter camping, although there is no maintenance, signage, or winter support of any kind.
