I'm about to start constructing some singletrack trail. One of my main concerns is keeping it as singletrack. Many times I've seen new singletrack go in, only to see ATV'ers force their way in and widen it. I have zero experience in creating trail, so I thought I would ask here for some tips. Amongst the most obvious items are: Keep the entrance to the singletrack as concealed and as tight as possible. I think I have this one covered. Route the trail in between tree stumps, boulders, fallen trees etc, anything with a limited opening that is below handlebar width. The terrain in question is an area of mature hardwood, on very hilly Canadian shield. Another idea was to route trail across the face of hills. Off camber trail increases the effective width on an ATV, where as on a bike it has no effect. I don't know how viable this idea is-there might be some concerns with erosion. It would also be harder to ride, especially the first few times it is ridden! I would like to tap the collective wisdom of the club here. So feel free to chime in. Mike.
