Cathedral Grove

Walking Through Vancouver Island’s Old Growth Forest

Cathedral Grove, located in MacMillan Provincial Park, is one of the most accessible old growth forests on Vancouver Island. Towering Douglas fir and western red cedar trees—some more than 800 years old and over 80 metres tall—create one of the Island’s most memorable natural stops along Highway 4.

Walking beneath the canopy, the scale is immediate. Massive trunks rise overhead, the air cools, and the forest becomes quiet and still. It’s an easy stop on the drive, but one that stays with you long after you leave.

A Star Wars Movie?

Cathedral Grove has also appeared in major productions, including Star Wars VI: Return of the Jedi, where director George Lucas used the towering forest to represent the Ewoks’ home world, and Jurassic World: Dominion.

Exploring Cathedral Grove Trails

Highway 4 divides Cathedral Grove into two distinct areas, each offering short, well-maintained trails. Most visits take 30 to 45 minutes, though it’s worth taking your time.

South Trails: Big Tree Trail & Living Forest Trail

The south side features some of the largest Douglas fir trees in British Columbia, including an 800-year-old tree with a trunk measuring over nine metres in circumference.

North Trails: Old Growth Trail & Cameron River

The north side offers a quieter experience, with looped trails that pass through dense cedar stands and lead toward the Cameron River and nearby lake views.

Slow Down and Look Up

Cathedral Grove is easy to visit, but it’s worth slowing down once you arrive. Look up into the canopy, notice how the light moves through the trees, and take in the stillness of the forest.

Even a short walk here gives a sense of scale that’s hard to find elsewhere on Vancouver Island. These trees have been standing for centuries, and spending a few extra minutes in the grove offers a different perspective on the age and presence of the forest.

A First Nations’ Legacy

The lands surrounding Cathedral Grove have long been cared for by local First Nations, including the K’ómoks, Tseshaht, and Te’mexw Nations. These forests have supported communities for generations, providing materials for shelter, transportation, clothing, and tools.

Western red cedar, often referred to as the “tree of life,” played a central role in daily life. It was used to build canoes and longhouses, weave clothing and baskets, and create tools that were essential for living on the coast. The surrounding forests were, and continue to be, part of a broader cultural and ecological relationship with the land.

In the 1940s, logging pressures threatened the area before H.R. MacMillan donated 136 hectares in 1944. This led to the creation of MacMillan Provincial Park in 1947, helping preserve this old growth forest for future generations.
