For years I’d heard it was possible.
For years I’d heard those roads were blocked. And there are signs on the roads heading west from Horne Lakes Caves saying there is NO through road to Alberni.
Happily, on the gravel road I bumped into a cyclist coming the opposite direction who had just ridden from Port Alberni. He told me it was pretty easy on a bike. The roads are blocked for motor vehicles.
This is logging country. Seems to me the wood left behind is an extreme fire hazard.
I’d originally been headed up trying to find hiking trails near Cherry Creek.
Instead, I decided to wild camp at a lovely spot beside Lacy Lake.
I had trouble keeping my eyes open ’til dark.
Up early with the sun. Enjoyed several mugs of coffee.
This trip was a gear test for longer BikePacking trips. And my system was NOT perfect.
There are many ways to get to Port Alberni. The advice I got was to go as direct as possible. I took this rough trail.
That worked. But it would have been better on a mountain bike than my hybrid.
I came out close to the Motocross Track.
From there on to the lovely Log Train Trail into town.
After a stop at Tim Horton’s I decided to cycle the highway back to my parent’s place in Parksville. It’s busy. Many trucks. But there is a fairly wide shoulder.
The highlight was a stop at Cathedral Grove.

Hi Rick, this looks like a great trip you had!
My wife and I are bikepacking a south island explorer loop leaving from our home in Victoria and hesding to Port Alberni through Carmanah Walbran and are hoping to avoid riding the Alberni highway to get back to the east side of the island if possible.
I’d love to chat a bit about this route if you’re open to sharing some intel with a fellow cyclist.
Cheers, Jesse
Sure. I’ve cycled Port Alberni to Horne Lake a few times in recent years. Each time I used the free Maps.me offline map. Each time going slightly different ways. Landmarks I’d recommend, however, are “Lookout” (a walk up hill off trail), Lacey Lake, coming out near the campground at Horne Lake.
From Port Alberni, I’d start from Coombs Country Candy Store rather than the Motocross Park which is hike-a-bike. … https://www.trailforks.com/route/port-alberni-to-horne-lake/
Depending on the day, it can be MUDDY in places.
As an alternative, you could ride Port Alberni to Comox, instead. Much better logging roads.
Again there are many variations. BUT you’d look for the logging road called “Comox Main”. https://rickmccharles.com/2020/05/10/cycling-great-central-comox-lakes/
Awesome, thanks for the landmarks and the maps it’s much appreciated
I’m quite looking forward to exploring the area by bike rather than by car this time around.
