Tagged a few 14ers but ready to go higher? Jessica R Hamel headed to the top to Orizaba and came back with these insights.

Earlier in March, I found myself playing Tetris with a new backpack, a large duffel bag, and a pile of gear. In just a few days, I would be joining three other women to climb the tallest mountain I had ever been on, Pico De Orizaba (18,491′), to raise money for Big City Mountaineers.
I’ve summited plenty of 14ers in Colorado and, heck, I’ve even run 100 miles over a day through the mountains. But this trip welcomed me to a whole new world of high-altitude mountaineering. Something was telling me it wouldn’t be like any experience I’d had in the mountains. I was right.
Thinking of climbing to new heights? I learned a few lessons during the trip that might help make your trek a little more enjoyable.
Author’s note: Deuter, La Sportiva, and Nemo sponsored the trip in support of Big City Mountaineers. If you’re Interested in learning more about Big City Mountaineers, find details here.
Tip 1: Get Cozy
Much of your time spent on a high-altitude mountaineering expedition will be resting. Well, what I mean by resting is lying around while altitude wreaks havoc on your body.
This is the acclimatization process. You need the rest. I made the mistake of trying to jog 40 feet for a cute picture and was kindly met with a pounding headache. So bring relaxation essentials.
For me, that was a solid, cold-rated sleeping bag, a big warm puffy, playing cards, and tea. I used the NEMO Sonic 0-degree as my bag and the La Sportiva Tara 2.0 for my jacket.
Most of my day and night was spent cozy in the bag. It was warm enough for the cold nights in the hut and its venting “Thermo Gills” cooled down the bag when things warmed up during the day. The “gills” are zippable vents in the middle of the bag that let more air flow to the core when unzipped.
When I needed to escape my cocoon to play cards or attempt an acclimatization hike, a warm jacket was key. The La Sportiva Tara 2.0 kept me comfortable. Packed with 700-fill European goose down, it has a wind and water resistant finish and is a versatile puffy.
I planned this as my heavy jacket for summit day, but it also worked for resting. We had a pretty warm summit, but with a layer or two underneath I would’ve been prepared for most temps. My favorite part of the jacket: deep pockets — perfect for plenty of snacks.
Tip 2: Plan For Poor Appetite
Eating right is essential to enduring altitude. Unfortunately, your body will tell you otherwise. At altitude, the body burns a lot more calories, but the brain doesn’t send hunger signals to compensate. It’s quite the conundrum.
