Hiking trails have been developed in the Carmanah valley, but visitors are discouraged from entering the Walbran section until ecological assessments are performed to determine possible negative impacts on sensitive habitat. Access is by gravel logging road from Port Alberni, Lake Cowichan, or Port Renfrew.

Ecology

This area lies within the coastal western hemlock (CWH) biogeoclimatic zone. Biogeoclimatic zones can be further divided into subzones, of which this park contains three. Immediately adjacent to the ocean lies the CWH Southern Very Wet Hypermaritime subzone, which is intimately shaped by the forces of the sea. This subzone is often referred to as the "spruce fringe forest" and is characterized by the dominance of sitka spruce, which is specially adapted to withstand the magnesium salts of sea spray. Other characteristic species include leatherleaf polypody fern and evergreen huckleberry.

Just inland is the CWH Submontane Very Wet Maritime subzone, which comprises the majority of the area of Carmanah Walbran park. The dominant coniferous trees here are western hemlock
