on-site camping, no vehicle - lining up?

I’m flying into Denver tomorrow and catching an airport shuttle out to Lyons with a bagful of gear to set up camp.

I know there’s the vehicle line for onsite camping, but what’s the procedure if you don’t have a vehicle? Is there some sort of no-vehicle line/entrance?

Sorry, only been once a couple years ago and had vehicle camping onsite, so not sure how it will work this way.

Thanks for any help.
