Canada’s largest tree, the Cheewhat giant. Love visiting this old tree in Pacific Rim National Park. Not the easiest specimen to photograph but just fascinating to go and see, if you can find the trail that is Canada's largest tree, the Cheewhat Giant, grows protected in the Pacific Rim National Park Reserve on southern Vancouver Island in the territory of the Ditidaht First Nation. This massive western redcedar measures 182 feet (55 m) tall and 20 feet (6 m) wide. It’s a true wonder to behold.
