Staying Connected

When it comes to modern telecommunications, Yellowstone and Grand Teton national parks have extremely limited infrastructure: Lack of connectivity is the rule, not the exception. These are not the best destinations for those who need to check e-mail every minute -- or even every day. The lodgings in the park typically lack Internet connections and even room phones are not the norm, but cell service continues to expand.

Cellphones

The parks have several cell towers in developed areas. Cell service is widely available on the floor of Jackson Hole throughout Grand Teton National Park; in Yellowstone, it is available in Canyon, Grant, Mammoth Hot Springs, and Old Faithful villages but largely unavailable on the roads and in wilderness areas. Cell service is available in all of the gateway cities.

Internet & E-Mail

Wi-Fi is prohibited at Lake Yellowstone Hotel, Roosevelt Lodge, Old Faithful Inn, Old Faithful Lodge, Lake Lodge, and Mammoth Hot Springs Hotel, but the concessionaires are permitted to offer it at other lodgings and general stores. However, as of this writing, it was not available. In Grand Teton National Park, Wi-Fi is available in public areas at Jenny Lake Lodge, Jackson Lake Lodge, Signal Mountain, and Colter Bay Village. Internet access is widely available in all of the gateways, but notably slow in Gardiner and West Yellowstone.
