What to wear and pack for Aspen

Cold mornings, strong sun and a town that dresses well but casually. What to bring, and what is easier to have waiting for you.

Aspen sits at 7,908 feet. In January, highs are about 32°F and lows near 10°F; in July, about 76°F by day and 48°F at night. Pack in layers, bring boots with grip for icy streets, and take sunscreen and sunglasses in every season. Skis and boots are easier to have fitted at the house than to fly with.

Temperatures are NOAA's 1991–2020 normals for Aspen; altitude guidance from the CDC and Aspen Valley Health. Checked September 2026.

IVEvery season

What people forget

Sun protection

At nearly 8,000 feet the sun is strong all year, and snow reflects it. Sunscreen, lip balm with SPF and good sunglasses.

Moisturizer and water

The air is very dry. A refillable bottle, lotion and saline spray help, especially the first two nights. The first 48 hours.

Medications

Bring prescriptions with you. If anyone has had altitude trouble before, speak to a doctor before the trip.

Grip

Slip-on traction cleats for town boots on icy evenings, especially for older guests.

VOur view

What not to pack

Your own skis, unless you love them

Rental delivery means nothing to carry through airports or into a car.

Formal wear

Aspen dresses well but casually. Unless there's a gala or a wedding, smart-casual covers every dinner.

Food and basics

Have the house stocked before you arrive instead. Grocery stocking.
