Camping with no car is totally allowed. All you need is your Centeroo Ticket and your stuff, and you are welcome to walk in and join a friends camping accommodations or head to the tent only Sputnik area to set up your own campsite at no extra cost.
You are also welcome to be dropped off at the edge of the campgrounds. Note that we do not have special lines or drop-off zones for this - we dedicate our car lanes to help the vast majority of traffic that is here to camp.
