When you receive your permit you get a tear-tag for each boat. I'm curious as to what stipulations there are on separation. Are you required to use the same campsite, or if someone so desired could they make their own camp at a seperate site? I just want to make sure I'm following the rules and not using poor etiquette. A group member is a primitive camper and would probably enjoy the seclusion. Just want to make sure I have my facts straight before I discuss the trip with him.

Every person on a permit has to share one campsite.

There are no primitive campsites available using a regular permit. There are PMA’s in the bwca, you must stop at USFs station to get approval to use those areas, probably more quizzing and more rules to follow.

But don't all those on a single permit still have to camp together?

Splitting off for a more "primitive" camping experience is understandable. PMA's aside, the BWCA is not primitive camping and there are lots of great places for that. In the BWCA campers must camp at the same site and no fires except in fire grates.
That said if you want to haul your bivy back into the woods and find a clearing (not make one) and spend the night alone I think the Forest Service would be ok. But not too far from the fiberglass throne, please. I have seen TP mine fields in primitive camping locations. Thankfully not in the BWCA.

Yes

The question was whether all parties had to camp together. Thank yall for the answer. I was sure that was the case but wanted to double check if there was the option in case he wanted to do his own thing.

Just to clarify, this is listed on the Forest Service rules and regulations page:

Q: Where must you camp in the BWCAW?
A: At a USFS designated campsite. How do you know it's a designated campsite? A campsite has a USFS fire grate and latrine. All group members listed on the permit must camp together.

Just to clarify the opposite, up to 9 people on up to 9 separate permits may camp together. You should see if your friend could get their own permit and then have the choice of camping with you or at a different campsite.

If that person gets a separate permit for the same EP, you could start and finish together (provided not >9 people 4 boats) and he could still have his solo nights.
If he gets a permit for another EP, you could start separately and map out a plan for intersecting routes, which could be fun and give you the best of both worlds, while still within the rules.
