"Summitted via the north chute, an unofficial and messy extension of the Abineau trail. I started the morning at 3,400ft and ended up at 12,635ft. Brought about a nasty case of altitude sickness but that is my fault for rushing into this one and not taking time to acclimate. Top notch views though!" — MikeERodriguez • Sep 10, 2024
"Hiked Humphreys Peak again, this time in perfect conditions, it seemed now moderate with some hard stretches.
As always, be prepared, listen to your body and know your limits, when hiking this and in general. " — alexandra-melaniecastellano • Aug 12, 2024

Ice & hard packed snow on first part of hike, that is when you are in the 🌲 forest, below tree line.
Poles were very helpful, for balance, lots of focus needed for finding right steps, not to slip. I had YakTrax but didn't need to put on.
💨 Once on saddle, wind picked up lots....we put on more layers and decided to head to peak. Extreme winds, increasing, we had to literally crawl, get down on ground, lay flat, wait...take a few more steps, must have been up to 70mph.😳
On way back, the ice turned into slush, so lots of sinking in, slipping, muddy ......all made for a long day !!
Also, keep in mind, altitude of start of hike and the gain of another 3,400 feet, your lungs will feel it. Train for it, we arrived night before. That part would not have been that bothersome, except higher up, with the crazy wind rushing into your mouth and lungs, made it very hard to breathe. Little stops, catch breath, slow down.....
🙌🏼 Huge shout out to our hiking friend (experienced on Humphreys) for taking me up there and not giving up either!

"The trail is a road to the lookout tower. It seemed to just keep going up and up without any plateaus. Nice challenge for an early morning. Very few people on the trail while we were there." — brandydanielson • May 6, 2024
"It was a challenge as by late morning it was snowing rather heavily with winds of 50+ MPH, and 70+ at the summit. The weather conditions made for a true adventure. The new snow and drifts made route finding pretty difficult. Above the treeline, there are white wooden poles along the trail, which are helpful, but they are usually spaced too far apart. With the snowfall, I would HIGHLY recommend crampons. I had mini-spikes which worked well on the compacted snow in the early morning, but were virtually useless when several inches of new snow fell. Further, my hard shell rain jacket (Columbia) and pants were true lifesavers. They worked spectacularly to keep me dry and block the wind." — MichaelV • Dec 22, 2023
