Cathedral Grove

Cathedral Grove is a must see place on the route to Tofino on Highway 4. The grove is home to many trees that are over 1000 years old, and is a great demonstration of a forest that has survived the natural elements.

This is the easiest place to get the big tree experience on Vancouver Island.

Vehicle Requirements: Any vehicle
Time Required: 15-60 minutes

Big Tree Trail

The Big Tree Trail on Meares Island, near Tofino is an incredible walk that takes you around a portion of Meares Island, weaving beneath massive old growth trees, and underneath the “Hanging Garden Tree”, which is one of the largest known Western Red Cedars on the coast. The trail takes roughly an hour to complete, and you could easily spend half a day here marveling at the big trees and enjoying the views.

Eden Grove is home to several of the largest Western Red Cedar and Douglas Fir trees on the West Coast, and also features “Big Lonely Doug”, a massive fir tree that was left behind by loggers a long time ago. Eden Grove is definitely worth checking out if you are in the Port Renfrew area and can be combined with Avatar Grove very conveniently.

San Juan Spruce

The San Juan Spruce was formerly Canada’s largest Sitka Spruce, with an absolutely astounding trunk and massive scale that is hard to comprehend. In 2016 the San Juan Spruce was hit by lightening and much of the trunk has collapsed, though there is still a formidable trunk to see today. This was one of the largest trees on Vancouver Island and definitely worth stopping to see if you are in the Port Renfrew area. The surrounding San Juan river valley is very beautiful with gorgeous water flowing through the small river at the heart of the valley.

Difficulty: Medium
Region: Port Renfrew

Carmanah Walbran Provincial Park

Carmanah Walbran is known as being one of the last wild forest ecosystems in Canada, with one of the most significant swaths of old growth trees growing in the valley. This is a tough area t visit, mostly because of the long logging road access to reach it and the lack of cell service and amenities. You are truly in the wilderness here, passing through a maze of logging roads to access the area. Once you arrive, there are several trails that you can hike through various portions of the valley, to visit different trees and areas within the forest.

Difficulty: Difficult (Lack of services, no cell service, long approach road)
Region: West Coast, between Port Renfrew and Bamfield, but accessed from Lake Cowichan.
Vehicle Requirements: High Clearance, 4x4 Recommended

Cheewhat Giant

The Cheewhat Giant is the largest tree in Canada an one of the largest Western Red Cedars in the entire world. This tree will completely mess up your sense of scale, as you feel like a tiny bug next to it. It would take so many people to connect hands around the tree, that we’re not sure it’s ever been done! This tree is somewhat near Carmanah Walbran, so combining the two into one adventure can make a lot of sense. If you are coming to Vancouver Island and love big trees, the Cheewhat Giant wont disappoint!
