Heat / Sun Protection, Death Valley National Park
Should you find yourself visiting Death Valley in the midst of a 120 pluis degree heat wave, be prepared with lightweight clothing, sunscreen, a hat and lots of water. Those opting for the more moderate temperatures in October through May should keep in mind that nights can get pretty chilly. In late November, evening temperatures dropped into the 40s (f). Daytime highs during this time of year rarely break 70, although there can be an occasional 80 degree day. Even if its not sweltering, sunscreen is always a must, as are comfortable walking shoes.
Last but not least, if you'd care to indulge in the fine dining experience of the Furnace Creek Inn, bring something other than a pair of shorts. Jeans are permitted, but only after 8:30. I don't know the reason for the change in dress code, but I read that last part in the guest services book.
Toiletries and Medical Supplies: Keep in mind that services are scarse in Death Valley. Furnace Creek has a general store and Stovepipe Wells has a convenience store. But its advisable to bring along any medical supplies or specialty products you think you will need as its unlikely that you'll find them here.
I wore a Teva sandal and did fine for the most part except for one hike at Golden Canyon where there was quite a bit of rock scrambling near the end. If you plan to hike a lot I'd get proper hiking shoes.
Toiletries and Medical Supplies: Water, water, water. Pack your lunch too. There are few places where you can buy food, and often, there's little there (nasty prepacked sandwiches) and the lines are long. Sunscreen.
Photo Equipment: You'll want a camera for this place.
Miscellaneous: There's probably more to worry about in the summer time. Check out the official website for what they suggest.
Sturdy shoes (the road is hot!).
Light, comfortable clothes.
Sun hat, sunglasses.
Toiletries and Medical Supplies: Sunscreen.
Cream for your lips.
Miscellaneous: Take lots of water with you and drink it.
Read the paper you get at the entrance. It has lots of tips and a good map on the back.
Light clothing, while covering the body. Remember, you are in a desert. Clothing helps keep humidity in and avoid burning. Sandles are out of the question.
Photo Equipment: Lots of film and a tripod for still night shots under the moon.
Miscellaneous: WATER, WATER, WATER and a full tank of gas.
Clothing/Shoes/Weather Gear: Tank Top or nothing for man. I said this is because I love sun tan and I always enjoy sunshine wherever I go. So you need Sun Tan Lotion.
Films that are appropriate for a lot of (sun)light
Miscellaneous: Sunglasses are necessary and best to also have a baseballcap or hat against the burning sun.
