Formerly called the Vancouver Island Spine Trail (VISpine), the Vancouver Island Trail is planned to end up close to 800km long.

About 95% of the Trail has been located and is defined on the ground well enough to be followed/hiked.
However, much of the route north of Port Alberni is not officially open since gaining the permission and support of several Indigenous Communities is on-going and a number of administrative arrangements (land use agreements, Section 57 approvals etc.) have not yet been completed.
Where the Trail is located across private forest lands, detailed planning and location of the trail has been progressing following completion of a Memorandum of Understanding that reflects the co-operative working relationship between Vancouver Island Trail Association (VITA) and Mosaic Forest Management, the timberland manager for both TimberWest and Island Timberlands. …
Current Status of the Vancouver Island Trail
The southern section from Victoria to Port Alberni you can do right now. Brendan Sainsbury cycled it. I’ve cycled all of the southern section, as well — and would say it’s better cycling than hiking.
Alex and Sarah hiked the entire island summer 2021. For them it was 40 days of backcountry camping and nights in motels when they hit small towns.
Magpie and her partner hiked it summer 2020 putting together a LONG video trip report. Watch that here.
