January in Grand Teton National Park is a shoulder month: highs around 26°F, lows around 6°F. Crowds: very quiet — #8 busiest of the park's 12 months. Deep winter — the park itself is snowbound; Jackson Hole's ski season is the draw, not the trails. The editorial best window here is July & September.
