What to Wear at the Grand Canyon: 7,000-Foot Sunrise Layers, Grippy Trail Shoes & Sun Gear

First-time visitors driving up to the Grand Canyon from 40°C (104°F) Las Vegas or Phoenix in shorts and tank tops are often shocked when they step out of their car at the South Rim for sunrise or sunset and start shivering! Because the South Rim sits on a high pine plateau at 2,134 metres (7,000 feet) elevation with bone-dry 15% humidity, daily temperatures swing by 16°C to 20°C (30°F to 35°F) between dawn and mid-afternoon!

Five Essential Packing Rules for the Grand Canyon

1. Dress in Peelable Layers for Sunrise & Sunset (Fleece / Packable Puffer + Windbreaker): in spring and autumn (April, May, September, October), sunrise at Mather Point is routinely 0°C to 5°C (32°F–41°F) before warming to a sunny 22°C by 13:00 PM! Even in July and August, bring a warm fleece or light down jacket and long pants for sunrise, sunset and night stargazing, layered over a breathable moisture-wicking t-shirt and hiking shorts/pants for midday!
2. Trail Runners or Hiking Boots with Deep Lugged Tread (Never Smooth Sneakers or Sandals Below the Rim!): the switchbacks of the South Kaibab and Bright Angel Trails are covered in a fine layer of loose red sand, limestone gravel and mule dust over steep rock steps—smooth-soled fashion sneakers (like Converse or Vans) and sandals slide like marbles on the downhill steps! Wear broken-in trail runners or boots with real lugged grip (and bring collapsible trekking poles to save your knees!).

3. A Wide-Brimmed Sunhat (With a Chin Strap!), Polarized Sunglasses & Lip Balm: at 7,000 feet elevation, UV radiation is noticeably stronger than at sea level, canyon wind will blow a loose baseball cap straight over the cliff edge, and the dry desert air chaps lips and skin within hours—pack SPF lip balm, saline nasal drops and high-SPF sunscreen!
4. A 2-Litre Hydration Pack or Two Wide-Mouth Water Bottles + Salty Snacks: carry at least 2 litres of water per person even for a 2-hour morning hike to Ooh Aah Point or the 1.5-Mile Resthouse!
5. Visiting Between November and Early April? Pack 'Microspikes / Ice Cleats'! Because the upper 500 metres of the Bright Angel and South Kaibab trails face north in winter shadow, packed snow and solid ice linger on the top switchbacks from November through March—a pair of slip-on rubber-chain microspikes (also sold at Canyon Village Market!) is mandatory to hike below the rim in winter! Check seasonal weather.
