Yosemite National Park Cellular Coverage
Yosemite National Park has more cellular coverage within park boundaries than most other parks in the National Park Service. Verizon, AT&T and T-Mobile serve several areas of the park.  There is also a new site approved in adjacent Sequoia National Park. See the updated map of cell sites in that area, below.  Also, See Notes.

Notes About Wireless Coverage in Yosemite National Park:
  • There are several cellular sites located within Yosemite Park boundaries and some just outside the park.  There is usable coverage in most of Yosemite Valley however it is not available in all locations including The Ahwahnee lodge. These sites serve developed areas of the park and their signals may be accessible from points far away from these locations, but that coverage can be variable and unreliable.

  • Variations in topography and elevation affect cellular coverage in the park significantly.  In developed areas, wi-fi is also available but it is provided by private concessionaires and not by the Park Service.

  • The coverage area shown is approximate but after field checks we found the coverage can be available well beyond what is shown on the maps.
