Camp Four has shared campsites and shared food lockers.
The map below has the campsite numbers, location of the restrooms, the trailhead for the Upper Yosemite Falls hike and the location of the largest boulder within the campground, Columbia Boulder, (or Big Columbia), which has the “world’s most famous boulder problem” – the route named “Midnight Lightning.”

(As of fall 2017: “the (Camp Four) parking lot is being expanded, bringing the capacity to 130 vehicles . . . A new comfort station is also being constructed in which showers will be included. This will be the first park campground that will provide shower facilities for people staying in the campground.”) As of the start of 2019 it looked mostly completed. When the shower house is finished you will find it off of this map to the lower right.
Camp 4 is first-come, first served. Camp 4 (Camp Four) “is extremely popular; it’s very difficult to get a spot.” Some times of the year you register with a person at the kiosk shown on the map, some times of the year you self-register.
Official details on how to register once you get to this first-come, first served campground are at:
(From the park website: “Within Yosemite National Park, you may not sleep in your car or RV except in a campsite that you’re registered to stay in (except at Camp 4, where sleeping in cars is not allowed because it’s a walk-in campground). Sleeping in your car along the side of the road is also not allowed.”)

The resident Ravens will take any food you leave unattended on a picnic table. Keeping food within arm’s reach is a wise idea at each of the hotels and campgrounds. The park warns: “If your food is stored improperly, you will be cited for improper food storage (fine of up to $5,000).” See also an index to over a dozen park webpages with park laws, rules, regulations and policies.
