...but we take a wrong turn just 200m down the track, by not following to the letter the instructions on the sign.
Turns out there are TWO railbeds leading out of the Lake Cowichan community, the northern one an old abandoned CP railbed, and the southern one the TCT (goes through a park, with trestles, etc).
The forest is lovely and green, no traffic, and NO ATVs! Yay! The trail is muddy and this makes for interest for the kids, you can't just put it on autopilot. We finally end up in North Cowichan, at Sherman Road, quite near HWY 1, after a 3.5 hour ride. Consensus: more fun than yesterday!
And, bonus, we still have the "real" TCT to explore for another day!
