Mer Bleue Bog is one of the largest bogs in southern Ontario and arguably the most important natural area in the Greenbelt. Ecologically, Mer Bleue is an especially valuable example of a northern ecosystem — more typical of the Arctic than the Ottawa Valley — and it has been designated an internationally significant wetland under the United Nations' Ramsar Convention.
The most striking feature of the area is the bog mat itself, a “sea” of deep, saturated peat overtopped by open heath and stunted to moderate-sized black spruce and tamarack trees.
The mat is home to a variety of plants, some of which are rare, but almost all exhibit unusual characteristics enabling them to survive in the demanding environment.
Those interested in education can stroll around the 1.2-km interpretive trail on a boardwalk that crosses a peat bog, while those wishing exercise may hike up to 6-km through forest on the edge of a sandy escarpment. After either walk, visitors may rest at the numerous picnic tables located near the parking area.
