To give a complete idea of how I think things ought to be, I would have to wander off into the never-neverland of how I think society should be organized, principles of individual rights, property rights, etc. Simply taking the world as it is, and trying to say what principles I think should govern trail use on public land, this is my thinking.
First, I wouldn’t think that the goal would be to adhere to a principle of minimal impact, because the logical conclusion of that is simply to close the trail to everyone.
The more sensible question is to ask what is the trail designed for, and what uses are compatible with that. There is no shortage of trails, so it’s not a question of sharing out a scarce resource. There’s nothing wrong with saying that this trail will be for this, and that trail will be for that. There’s room for everyone, and we don’t have to be on top of one another.
The National Scenic Trails are designed for long-distance, let’s say ‘overland travel’ so as not to prejudice the matter. Obviously, they’re not for cars. Are they for bicycles? No, bicylce touring is done on highways. Governments have started adding special bike lanes to make that easier and safer.
For mountain bikes? No, that’s pretty much a day sport. The idea, as I understand it, is to go very fast downhill, not to travel long distances.
ATVs? No, again that’s a day sport.
Horses? Well, this is a bit trickier. For most people, horseback riding is probably a day sport, but it is possible to do long treks on horseback and/or with a pack animal. I don’t know if anyone has ever done an entire trail that way. It seems like it’s a rather dangerous thing from the perspective of the animals–keeping them fed, watered and healthy, protecting them from predators. Still, week-long horseback treks are probably not that uncommon. In my mind, the jury is out on that one. I don’t know what alternatives exist for long-distance horseback riding, or how much use the scenic trails are to them.
Hikers… obviously, these are the people that the long-distance trails were designed for. Any other use of the trail should be consistent with them actually being able to use the trail. (In other words, they shouldn’t be in danger of being run down by a hurtling mountain bike.)
So I think that the scenic trails ought to be reserved primarily for hiking, but that there may be a place for horses on the trail too–not sure. If people want to tear up the woods on an ATV, or tear up themselves on a mountain bike, there are other places to do it.
