Highlights in this park

Cathedral Grove, located in MacMillan Park, is one of the most accessible stands of giant Douglas fir trees on Vancouver Island. The park protects and preserves an internationally significant representative example of Douglas fir old-growth forest within the Coastal Western Hemlock Biogeoclimatic Zone.

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.

A severe windstorm on New Year’s Day in 1997 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 clean-up 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.

Advisories

Safety information

Cathedral Grove in MacMillan Park is an old forest. Its large trees will continue to live for many more years, but root system disease will cause some trees and branches to die. They can fall without warning. Please stay off the trails on windy days.
Please use caution when driving, parking, and walking along or crossing the highway within the park.
Smoking is prohibited in MacMillan Park.
Due to concerns about public safety associated with very high levels of use in the park and along the adjacent highway, BC Parks does not allow commercial filming within MacMillan Park from May 15 through September 15.

About this park

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 on 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.
