Some of the world's most beautiful scenery is found at high altitudes: California's Sierra Nevada Mountains, for example, where the altitude on major highways can top 10,000 feet. If you're planning a trip to high places, this checklist will help you keep comfortable and safe.
Learn About Altitude Sickness
Altitude sickness is a result of the body's inability to adjust to abrupt changes in altitude, which can result in breathing problems and fluid accumulation. It can occur as low as 6,500 feet and symptoms can start any time within the first three days. This is a potentially fatal problem, and you should know its symptoms and what to do if you feel affected.
Combat the Dryness
You'll find the air much drier in the mountains than at sea level. Take these along to stay comfortable:
Saline Nasal Spray: Dry nasal membranes are not only uncomfortable, but they can also cause nose bleeds. A few spritzes of this over-the-counter remedy can help a lot.
Extra-Strength Moisturizers Your skin will soak up moisturizers like a sponge. Bring lots of your regular stuff, or get something extra-strength and don't forget your lips.
Artificial Tears: Get individual packets of artificial tears and tuck a few in your bag.
Water Bottle Carrier: Buy the water once you get there, but a carrier helps.
Protect Against the Sun
High SPF Sunscreen: The sun will be bright in the desert, and at higher elevations there's less air to absorb it. Whatever you normally use, buy something stronger.
Hat with a Wide Brim: A baseball cap will shade your face, but not your neck. You'll be better off in a hat with a brim all around so it protects your neck, too.
Sunglasses: It's easy to leave them in the car, so find a way to remember them or pack a spare pair.
Motion Sickness
If you're driving to high elevations, you'll probably be going on winding roads. If you're susceptible to motion sickness, taking the wheel will likely solve the problem. However, if you can't do that, you may want to stock up on your favorite remedies to take along.
Driving in Winter
Under some conditions, tire chains (also called "tire traction devices") are required. You're most likely to need them on I-5 north of Redding, I-80 over between Sacramento and Reno, and US Hwy 50 between Lake Tahoe and Sacramento. They're also sometimes required on Hwy 58 between Bakersfield and Mojave, I-15 between Victorville and San Bernardino and I-5 between Los Angeles and Bakersfield.
