If your planning a stay at one of the province’s national parks this summer you may want to make those reservations sooner rather than later. With national parks free for the season as part of the Canada’s 150th celebration – reservation spots at many of Nova Scotia’s parks are filling up quickly. Cape Breton Highlands and Kejimkujik National Parks both officially opened for the season on Friday. Keji opened with campground sites for the weekend at 97 percent occupancy.
