The following is a series of etiquette oriented questions that arise around toproped climbing at popular cragging destinations. The answers to these questions should be adhered to at North American Climbing destinations. Locations outside of North America may have different etiquette issues.
Gear and equipment should not be placed directly under the wall. It's good to set-up a "safe" area away from the wall where you can relax without a helmet on and eat lunch. This will also keep the base of the wall from being crowded with gear and packs.
It's a good idea to consolodate your group's gear. Avoid allowing equipment and packs to be scattered around.
2) What if I have a large group and want to "take-over" a crag for the day?
It is not appropriate for a group to "take-over" a crag. Climbing areas are public areas that are open to everyone. As such, it is incredibly rude for a group to hold an entire area -- or even a few routes -- hostage for the day.
If you have a large group, you have a large impact on both other users as well as the area. The best thing that you can to mitigate that impact is to keep a low profile, allow others to work in on the wall that you're using. Never leave a rope up that is not being used to "hold" a route.
If you do have a lot of ropes up and other users wish to climb routes that you have ropes on, it is okay to allow people to use your ropes if they look like they know what they're doing. If they don't appear knowlegable and they are climbing on your gear, you could become legally liable if something happens to one of the climbers that aren't with your group.
If you've got moves, then offer to have a dance-off for the climb. Seriously, joking with people will often loosen them up. In most cases, people that have had a good laugh will be more polite and more open to allowing people to climb.
If the large group is very rude and refuses to give up a climb, then politely find another place to go. It's not worth lecturing an ignorant climber about crag ettiquete. More often than not, a lecture will just reinforce negative behavior.
4) Is it okay to use the same anchor bolts as the person on an adjacent route?
Yes and no. Will this cause the person next door problems? If so, they were there first. If not, then be sure to ask them before clipping in next to their carabiners. If they say yes, then clip the bolts, but be sure not to do anything that changes their set-up in any way.
5) Where should I go to the bathroom when I'm cragging?
If there is an outhouse nearby, always use that first. Avoid urinating at the base of the wall and always avoid urinating in cracks on a wall as this causes the smell to linger.
If you have to defecate, know the rules of the area. Some areas require the use of WAG Bags, while other areas require you to dig a cat hole and pack out your toilet paper. Never go to the bathroom on the ground, stack the toilet paper on it and then put a rock on top.
6) When should I say something to a person who is doing something dangerous?
This is up to you. I usually don't say anything unless there is real and iminent danger. If there is mild danger, I will usually chat with the people for awhile in a non-threatening way before providing any unsolicieted beta.
7) Is it okay to toprope the first pitch of a multi-pitch climb?
More often than not, the answer is no. This is a more complex issue than the others and it does depend on the route and the route's history. People who are doing multi-pitch climbs always have the right of way over those who will TR a climb.
Some climbs are multi-pitch climbs, but nobody does anything but the first pitch. In this case, all the other ettiquete rules apply. Other climbs are commonly climbed as multi-pitch routes and are seldom done as single pitch routes. Such climbs should not be toproped.
8) Is it okay to yell beta at people who didn't ask for it that I don't know?
No, many climbers like figure out the moves on their own.
Climbers who keep these concepts of etiquette in mind will almost universally have a much better time with a lot less conflict at the crags. And climbing isn't about conflict. It's about having fun...!
