Nothing spoils a good walk in the great outdoors like someone who simply doesn't know, or doesn't care, about the rules of the trail.

They're not hard to learn. They're not overly cumbersome. Most of them aren't even rules as much as they are fervent suggestions.

Still, when you're hiking, whether it's a short day trip on a mile loop in the closest state park or a thru-hike on the Pacific Crest Trail, you have to know them. You have to know that, for example, blasting Skrillex from a wireless Bluetooth speaker strapped to your backpack is not cool. And it's not because it's Skrillex. It's you.

"That's a pretty big pet peeve of mine," says longtime hiker Whitney "Allgood" LaRuffa of Portland, Oregon. "That one is bad. I generally try to stop and educate others about that."

The basics of hiking etiquette are almost a given. The Leave No Trace Center for Outdoor Ethics — see, it's about ethics, not law — spells them out in seven steps:

  1. Plan ahead and prepare
  2. Travel and camp on durable surfaces
  3. Dispose of waste properly
  4. Leave what you find
  5. Minimize campfire impacts
  6. Respect wildlife
  7. Be considerate of other visitors

You don't have to be Johnny Backpack to see that many people don't know the basics, though. Go out on a day trip. Head out on an overnighter. Too often there are too many people mucking it up for others.

Noise, like the guy with Skrillex, is one problem that crops up from time to time. But keeping the wilderness clean is a constant challenge, especially for the part-timers out there.

"So many people think that throwing sunflower seeds on the side of the trail, they think, 'Oh, it'll go away,'" says Christy "Rockin" Rosander, a hiker from Tehachapi, California.

“Even the little corner of a protein bar [wrapper]. That one corner," says Trinity Ludwig, a hiker from Boulder, Colorado. "I find so many corners."

The problem, of course, is what to do about it. What if you see people littering? What if you see them drop that corner, even accidentally?

Is it OK to bust them on it?

"I pick it up and bring it to them. I don't want to be mean or condescending to anyone in the wilderness. They have just as much right to be there as I have. I'm not special because I have more experience," Ludwig says. "So I always bring it and say, 'Hey, I noticed that you dropped this […] I just wanted to make sure this didn't end up out here in the wilderness.' You want to kill them with kindness.

"I feel like if you attack people and you're like, 'Dude, you just littered that, and that is sooooo bad for the environment,' then they're going to be like, ‘Wow, she's a bitch. It's just a bottle.'"

Says Rosander: "You tell them that's not part of how nature is out here, so you should haul those out. Instead of saying. 'Pick 'em up!' Some people don't listen, and they do get mad. I've had that, too."

That's a big key to etiquette on the trail: Making sure everyone knows that the outdoors are out there for everybody, not just the guy flicking his cigarette butt or the woman going to the bathroom too close to the stream — and then covering it, toilet paper and all, with a rock.

Again. None of that is cool. So speaking up is important, but it needs to be done the right way.

"The overwhelming response I get has been very positive. People don't even realize it," LaRuffa says. "It doesn't even register with them that it would be unacceptable."

Some basic etiquette — the American Hiking Society has a list — most people know, or should. Like:

  • If you're headed downhill, give way to uphill climbers (they're usually hard at work, with their heads down).
  • Give way to horses (they're bigger).
  • Stay on the trail. Don't cut through switchbacks. If there's a mud puddle in the middle of the trail, go through it. Don't make the trail wider.
  • Be aware. Listening to music — with headphones or earbuds — is fine. But don't listen at such levels that you can't hear other people (or a bear) coming up on you.
  • Say hi to other hikers. Be encouraging. Be positive. Lend help if they need it.

Other etiquette falls in the Leave No Trace realm. Like being considerate, which includes being quiet (especially when it's quiet on the trail) and not hogging up that great viewpoint by taking a half-hour worth of selfies.

"I'm probably a bit of a curmudgeon in some ways, but I also don't like a whole lot of electronics in the backcountry. People taking a picture from a mountain and posting a John Muir quote on it," LaRuffa says. "Dude, John Muir would roll in his grave if he saw you doing that. If the whole reason you're in the mountains is to take a picture of yourself on top of the summit that says 'The mountains are calling,' it’s like you missed the point of the mountains calling. The mountains are calling you to turn off, unplug and immerse yourself in nature."

Many hikers see modern technology in the wilderness as a kind of cop-out, but many view it as a critical tool. A device that has GPS and maps and helps you to stay connected while deep in the woods is something many just won't give up.

But, yeah … yakking on a cellphone while others are within earshot?

"I don't sit on top of Mount Whitney and talk to my kids aloud, because that is annoying," Rosander says. "But I do text."

In the end, hiking etiquette is mostly common sense about respecting both the environment and your fellow hikers. And on the occasion you need to enforce a rule — or, maybe, just point out a little etiquette faux pas — that's OK. Most hikers, rookies and long-timers alike, are good with a little well-delivered tip now and then.

"If you’re really nice about it, they might ask for more information, or they may give you space to give you more information," Ludwig says, "and then you're doing the wilderness good."
