Warm desert escapes
Death Valley, Joshua Tree, Saguaro, and the Everglades are at their most comfortable in winter. They are busier on holiday weeks but pleasant on weekdays.
Snowy solitude
Mountain parks like Yellowstone and Rocky Mountain are very quiet in winter, with snowshoeing and wildlife in a hushed landscape, but most roads are closed to cars.
Plan for limited services
Winter means reduced hours, closed roads, and fewer open facilities. Carry cold-weather gear and confirm what is open before you commit.
