Lac Baie-des-Onze-Îles Site 4 is a backcountry canoe-camping site within La Mauricie National Park, reached by paddling from the Lac-du-Caribou parking lot. The journey begins with a 0. 3 km moderate portage to Lac du Caribou, followed by approximately 5.

9 km of canoeing — roughly one hour and thirty minutes of paddling — to reach this fourth and most distant site in the Baie des Onze Îles area. The site includes a fire pit and is part of the park's western sector backcountry network.

Paddlers departing for Baie des Onze Îles must leave by 3 p. m. during the summer season.

Because Lac du Caribou sits at high altitude, strong winds and waves can develop quickly; Parks Canada advises securing all gear inside the boat and checking weather forecasts before setting out.
