Hotels in Yellowstone National Park, United States

Yellowstone National Park, spanning Wyoming, Montana, and Idaho, is famous for its geothermal wonders like Old Faithful and the Grand Prismatic Spring. Summers bring temperatures around 70°F (21°C), ideal for hiking the Grand Canyon of the Yellowstone trail, while winters drop to 10°F (-12°C), perfect for snowmobiling past frozen waterfalls and spotting wolves in Lamar Valley. During the summer peak, you can watch bison in Hayden Valley, but visiting in September offers cooler weather and fewer crowds.
