Attention Visitors – Important Notice!
Notice of Upcoming Trail Improvements
Upgrades to the south trail system will be taking place from November 18 – December 6. During this time, much of the south side parking area will be closed along with the south side trail system. Your cooperation and patience during these important upgrades is appreciated.
MacMillan Trail Facility Upgrade Project: Phase 1 Complete
This multi-year project will see an overall rebuild and upgrade of trail and interpretive facilities that will focus on accessibility, protection of environmental values and visitor information. Fall 2018/Winter 2019 saw the completion of Phase I of this project with work focussed on the north trail system.
Phase I deliverables included:
- 300 linear metre split rail fencing
- 375 linear metre trail surfacing (2m width, 3/8” high fines cart path mix – accessible surface)
- 80 linear metre elevated boardwalk/railings (<5% grade-accessible, screw pile footings – low environmental impact)
- Expanded trailhead landing adjacent to parking lot (Improved visitor safety and accessibility)
Phase II, scheduled to commence in Fall 2020, will continue work on the north trail system. This phase will focus on elevated boardwalk construction throughout the remainder of the north side trail system.
Future project phases will continue accessibility, visitor information and environmental protection upgrades to both north and south trail networks.
About This Park
Cathedral Grove, located in MacMillan Provincial Park, is one of the most accessible stands of giant Douglas fir trees on Vancouver Island. Here visitors can stroll through a network of trails under the shadow of towering ancient Douglas-fir trees, majestic pillars untouched by the modern world – some more than 800 years old.
Trails on either side of the highway lead visitors through the mighty stands of this coastal forest. On the south side you will find the largest Douglas firs – one measuring more than 9 metres in circumference. On the northern side of the road you’ll find groves of ancient Western red cedar standing sentry over nearby Cameron Lake.
The park has been restoring some of its trails after a severe windstorm on New Year’s Day in 1997, which changed the look of the park forever. The storm toppled hundreds of huge trees and obliterated sections of the trail system. Some sections of the trail system were so badly hit that they have never been reopened. Restoration and cleanup began almost as soon as the winds stopped, and although visitors will now find many of these huge trees lying on the ground, their value has not diminished. These fallen trees open the canopy to provide light, space, shelter and nutrients for the next generations of plants. Natural regeneration is beginning to restore the Grove’s pristine beauty and the park’s diversity, making a visit to Cathedral Grove all the more intriguing.
Improvements to MacMillan Park can be supported by “feeding” the donation tree next to the main trail; your contributions will be used for youth team trail projects, volunteer projects, revegetation projects and new signs. The park’s small size and accessibility has left it vulnerable to impacts from high visitor use. Please stay on designated trails, where you will find ample opportunities to view and photograph this bit of history.
Special Features: The park protects and preserves an internationally significant representative example of Douglas fir old-growth forest within the Coastal Western Hemlock Biogeoclimatic Zone.
Established Date: February 27, 1947
Park Size: 301 hectares

Nature and Culture
- History: The name “Cathedral Grove” appeared in correspondence to the provincial government in the 1920s. This colourful description of the stately trees is reputed to have originated from the Governor General Viscount Willingdon in April 1928. Cathedral Grove was a well-known tourist stop on the Alberni Road in the 1920s and 1930s when the timber was owned by the Victoria Lumbering and Manufacturing Company. For 15 years the public encouraged the provincial government to acquire the lands within Block 35, Cameron Lake area. The citizens’ organizations, The Associated Boards of Trade of Vancouver Island, petitioned the government in 1929 to preserve forever, for the public benefit, the well-known stand of timber at Cameron Lake, known as Cathedral Grove. In 1944 H.R. MacMillan, a well-known forester donated the 136 hectares of land for the perpetual enjoyment of the public in recognition of the unique stand of trees. Three years later, the area was established as a Class A provincial park.
- Conservation: The park protects and preserves an internationally significant representative example of Douglas fir old-growth forest within the East Vancouver Island and the Coastal Douglas fir Biogeoclimatic Zone.
- Wildlife: Many species of wildlife use the old-growth forest as their home including several types of woodpeckers, owls, insects, reptiles, amphibians, deer, elk, black bear and cougar. The Cameron River, which flows through the park, contains rainbow, brown and cutthroat trout.
