I've noticed that many trails are used in the morning and empty by afternoon.
Often because of the heat of the day. Nude, the heat doesn't bother me as much.
People tend to go less far, if they leave later in the day.
The trailheads are where most activity is.
The Forest Service isn't as concerned with disruptions of nudity if it is kept away from the trailhead where those people are. It is not likely that an authority will chase a naked walker any distance from the trailhead, or wait for hours for them to maybe come back to the trailhead dressed.
Sunday afternoon toward evening, people go walking after a long day, etc. Most people have left, however.
Sometimes, you know that the odds are that nobody is coming out.
Weekdays are significantly less busy.
The odds are approximately 97 to 3 that a person will object to nudity, or be offended out on the trail. Odds of trouble are even less.
CCTV, game cameras, people with binocs and telescopes, hunting hides, are stealth. There can be no claim for exhibitionism, if you are minding your own business and they sneak up on you. Nudity isn't illegal, being seen is illegal, if you are reckless about it, and then just a small area of the body, usually. There can be a claim for voyeurism, or spying on the others account. Nature isn't a public space like urban locations are. One has a certain expectation of privacy, especially when odds are that one will not encounter anyone else.
I gather that preserves, or reserves are smaller in Europe. Lookee was in Scotland, where there are bigger less touched, remote areas than south. I miss Milfmog's posts...and then, you over there, you don't have the legal inhibitions to free range action.
What do you do when you happen upon an off duty cop, or an authority in uniform out on a trail? Does he/she have a badge, ability to subdue, have backup, have a desire for hassle, have something better to do than enforce laws in the middle of nowhere.
Most cops don't even know the law well enough to know if they are in their jurisdiction, or not, in Federal lands.
The only arrest out on the trail, or say in the tooleys, has been frequented hot springs, or a beach that some hoohah wants to "clean up."
The other day, we backpacked two miles and camped in paradise. Sunday afternoon. I wore a kilt, she a short dress. Once we got into it, we didn't need cover, because it was remote and very few people were out there. A coupe of young guys walked by as we were pitching the tent and smirked. A dog walker and a birder the next day, neither had any issues with naked people and stopped to talk a bit. We took a mile walk from there, no backup clothing, no need, just act natural...but then, saw no one. Around the trailhead, there were encounters every few minutes. There were people with kids, teenagers, who knows what kind of kook's attitudes. Who needs the hassle?...I wasn't significantly uncomfortable in a kilt, unlike pants. The backpack and rocks in the trail were occupying my attentions. Still, it felt so much better to be nude in paradise. Nude belongs in nature.
