You can carry loaded in your campsite. However, if it is private as others have stated, then they could conceivably have a no-firearms rule, in which case they could ask you to leave or "refuse service" and have trespass law on their side as a means of enforcement.
You can take your firearm with you on a hike. You just can't have it loaded, but you can have loaded magazines handy. And of course you can't conceal it (unless you have it in a locked container or happen to qualify for the 12027 fishing exemption).
