What to Wear to a National Park
Choosing the right clothing for a national park visit depends on the park's climate, your planned activities, and how long you'll be on the trail. Here's a practical guide to dressing for America's most-visited parks.
The Layering System
Most experienced hikers use a three-layer approach:
- Base layer — soft cotton or moisture-wicking tee for mild conditions
- Mid layer — fleece pullover, hoodie, or crewneck sweatshirt for temperature swings
- Outer layer — windproof or rain shell for exposed ridges and alpine parks
What to Wear by Park Type
Desert Parks — Arches, Zion, Joshua Tree, Death Valley, Grand Canyon, Bryce Canyon
Light, breathable fabrics are essential. A wide-brim bucket hat provides critical sun protection on exposed canyon trails. Avoid dark colors in peak summer heat.

- Joshua Tree National Park Apparel
- Death Valley National Park Apparel
- Grand Canyon National Park Apparel
Mountain Parks — Rocky Mountain, Grand Teton, Glacier, Rainier, North Cascades, Lassen
Temperatures drop quickly above treeline. A mid-layer fleece or hoodie is essential even in summer. Pack a beanie for summit hikes and early morning starts.

- Grand Teton National Park Apparel
- Rocky Mountain National Park Apparel
- Mount Rainier National Park Apparel
- Lassen Volcanic National Park Apparel
Forest & Rainforest Parks — Olympic, Redwood, Great Smoky Mountains
Moisture-resistant layers and a hoodie handle the cool, damp air in temperate rainforest parks. Layer up for the Hoh Rain Forest and Smoky Mountain ridgelines.
Coastal Parks — Acadia, Olympic Coast, Everglades
Wind and salt spray make layering important even in warm weather. A light hoodie or long sleeve is useful on coastal cliffs and beaches.
Stargazing & Night Sky Visits
Standing still after dark feels dramatically colder than hiking in the same conditions. Desert parks in particular can drop 30 or 40 degrees after sunset. A warm mid layer and a beanie make the difference between staying out for hours and heading back to the car early. See our guide to the best national parks for stargazing for where to go and when.
Headwear for Every Park

Frequently Asked Questions
What should I wear hiking in a national park?
A moisture-wicking base layer, mid-layer fleece or hoodie, sturdy hiking shoes, and a hat for sun or warmth. Dress in layers — temperatures change fast on the trail.
Can I wear jeans to a national park?
For casual sightseeing, yes. For day hikes, lightweight pants or shorts plus a comfortable tee work better — jeans are heavy and slow-drying if they get wet.
