Questions & Answers
For outdoor adventures, it's good to come prepared in Jackson year-round for any adventure. It has famously snowed on Independence Day in Jackson Hole during the fireworks. Pack layers, as it can be hot and cold in the same day during the summer.
Around town, almost anything goes. Even the millionaires in Jackson tend to dress down for their time on the town. Denim pants or athletic wear are commonly seen, as is high-end Western chic apparel. Very few restauarants have a dress code, and even fewer enforce one. Even the most high-end restauarants call for "Jackson casual" or "dressy casual" wear, with the former translatable to nearly anything you want to wear.
Jackson Hole boasts year-round outdoor activities, but the options really open up in summer, fall, and winter.
In summer, visitors love the hiking, whitewater rafting, wildlife viewing, and access to the Tetons and Yellowstone.
In fall, you'll find that the crowds have died down and chill morning air is balanced by a radiant sun that still allows for deep access to the mountains. Wildlife is also in peak form going into fall, leading to numerous viewing opportunities.
Winter offers skiers, snowboarders, snowmobilers and other winter enthusiasts to play to their hearts' content. Jackson Hole Mountain Resort, Grand Targhee Resort and Snow King Mountain offern plenty of skiing options close to town.
Spring tends to be the quietest time of year in Jackson, largely because of iffy weather that can swing between bluebird spring days and dead-of-winter storms - sometimes in the same day. Spring skiing both at the resorts and in the backcountry can continue to be phenomenal, though avalanche danger can be high.
