Yosemite National Park has 13 popular campgrounds, each in a wonderful setting with sweeping views or forest canopies and plenty of room to relax. Seven of the campgrounds are on a reservation system. From April through September, reservations are essential and even the first-come, first-served campgrounds often fill by noon from May through September.
Reservations are required March 15 through November for Yosemite Valley’s car campgrounds and summer through fall for Hodgdon Meadow, Wawona, and half of Crane Flat and Tuolumne Meadows. Campground reservations are available in blocks of one month at a time, up to five months in advance, on the 15th of each month at 7 am Pacific time. Be aware that nearly all reservations for the months of May through September and for some other weekends are filled the first day they become available (often within minutes after 7 am)!
