Victoria Old‑Growth Hikes and Forest Walks

Greater Victoria offers several easy‑access walks where you can see big trees and remnants of coastal Douglas‑fir old‑growth forest close to the city.

Port Renfrew Big Trees and Old‑Growth Forest Hikes

Just two hours from Victoria, Port Renfrew sits at the heart of some of Vancouver Island’s most famous big trees and old‑growth forests. Known as the “Tall Trees Capital of Canada,” the area includes iconic sites such as Avatar Grove, Eden Grove, Big Lonely Doug, Red Creek Fir, San Juan Spruce, and Harris Creek Spruce.

Cathedral Grove and Central Island Big Trees

Cathedral Grove in MacMillan Provincial Park is one of the best‑known places in BC to walk among enormous Douglas‑fir and redcedar trees. Nearby, big‑tree hotspots like Mount Horne, the Cameron Valley Firebreak, and Mossy Maple Grove showcase both classic rainforest and lesser‑known groves threatened by ongoing logging.

Carmanah, Walbran and Remote Old‑Growth Rainforests

For prepared hikers seeking a wilder experience, Carmanah Walbran Provincial Park and the Central Walbran Valley protect some of the most awe‑inspiring old‑growth rainforest remaining on Vancouver Island. Trails and routes lead past massive Sitka spruce and western redcedar, along emerald rivers, and through valleys where logging and road building still threaten nearby ancient forests.

North Island and West Coast Old‑Growth Trails

The North Island and outer west coast host quieter big‑tree destinations such as Nootka Island, Flores Island, Spruce Bay Old‑Growth Trail near Port Alice, and White River Provincial Park. These remote rainforests often require more time, planning, and backcountry experience, but reward visitors with towering Sitka spruce, secluded beaches, and intact old‑growth valley bottoms.

Planning Your Old‑Growth Hike

Old‑growth hikes can range from short boardwalk walks to full‑day backcountry adventures. Keep the following in mind when planning your trip:

Check access and closures. Road conditions and trail access can change, especially around Port Renfrew and active logging areas. Some sites, such as Avatar Grove and Eden Grove, may have temporary closures or safety advisories.
Plan for driving time and fuel. Many big‑tree trailheads are reached via gravel forest service roads with limited services.
Be realistic about difficulty. Trails vary from flat and family‑friendly to steep, rough, and muddy. Research ahead of time and choose routes that fit your group’s experience and fitness.

Callout:
Avatar Grove and other sites may be closed or have limited access at times. Please check the latest updates before you go and respect any posted closures or safety directions.

Why Protecting These Trails Matters

Old‑growth forests now cover only a small fraction of British Columbia’s original forested landscape, and many of the big‑tree valleys popular with hikers remain unprotected. These ecosystems store vast amounts of carbon, provide habitat for species at risk, and hold deep cultural significance for Indigenous Peoples.

Across Vancouver Island, logging and road building continue to threaten old‑growth forests in areas like the Walbran Valley, Nahmint, Quatsino, and around Port Renfrew. The Ancient Forest Alliance works with Indigenous Nations, local communities, scientists, and supporters to secure lasting protection for these ancient ecosystems.

How to Visit Old‑Growth Forests Respectfully

Stay on established trails and boardwalks to protect tree roots, understory plants, and sensitive soils.
Follow Leave No Trace principles: pack out all garbage, avoid picking plants or fungi, and keep noise levels low.
Keep dogs leashed where required and give wildlife plenty of space.
Remember that many of these forests are in the territories of Indigenous Nations; respect local protocols, signage, and cultural sites.
