What sort of cell phone service coverage is there?
There is limited cell phone coverage in Yosemite, with the strongest signals in the populated areas of the park, including Yosemite Valley, Tuolumne Meadows, Wawona and Crane Flat. AT&T has a good signal in Yosemite Valley on Northside Drive for the full length of Yosemite Valley (Yosemite Village to Pohono Bridge) and up at Tunnel View and some locations on Route 120 with a line of sight view to Sentinel Dome, which is near where the cell tower is located. There is a weak signal in The Ahwahnee hotel (most likely due to the steel understructure) that can be improved by standing at a southwestern facing window, or outside the southwest side of the hotel behind the dining room. In the high country outside of Yosemite Valley, there is a sliver of a signal at the west end of the Olmsted Point parking lot, the Lembert Dome parking lot, and a strong signal at the Tuolumne Meadows Lodge. Verizon customers can often connect at Crane Flat and Wawona as well as most areas of Yosemite Valley.
