Packing for Aspen means preparing for mountain weather that can shift from sunny and warm to snowy and cold in the space of an afternoon. The 8,000-foot elevation means cooler temperatures than Denver, intense high-altitude sun, and dramatic temperature swings between day and night. This packing guide breaks down exactly what to bring for Aspen by season, from ski gear to summer hiking layers, so you arrive prepared without overpacking.

- Warm gloves or mittens (bring backup pair)
