Parks I've been to have done things like this. Spoiler Not warpus's pictures : The point to these is only partly to make it easier on the visitor. And in some places, it's about safety. But in a lot of these places it's about preserving the environment against excessive wear and erosion caused by the human traffic. Because what happens over time is that in even moderate traffic areas, that traffic damages things too much. Where trails aren't improved at all, that's commonly where they are far enough out in the boonies that there is not enough human traffic to be damaging. So this trail is odd, at least by my experience, in that you can see that it's getting quite a bit of traffic, as there's enough traffic to damage the ground, and you can see how many people warpus encountered. Yet it's not protected against that, and it's not marked enough to keep people on the trail in places, and it hasn't got anything for safety in the most unsafe places. Now different country, different standards. So they certainly don't have to do things the same. I'm just saying the difference is noteworthy.
