Hiking Mt Major
A brief post about my hike to Mt Major in May 2025.
For my trip to Mt Monadnock last year, we had initially set our sights on Mt Major, only to switch to Monadnock given its more favorable weather. This time, my friends and I found a weekend when we were all free, and decided to finally try out Mt Major.
Just like Monadnock, there was a network of trails around Mt Major, but overall they were mostly a notch easier than their Monadnock counterparts, involving less elevation gain, which would be perfect for my buddies that, in their words, “not been the most in-shape recently”.
So on the morning of May 18, we reached the parking lot for Mt Major at 10:35am, and pulled into the last “compact” spot. The journey there was especially memorable for the tranquil drive stretching between Hooksett and Alton, where New Hampshire’s verdant countryside unfurled before us like a pastoral canvas, offering a serene prelude to our mountain excursion.
Here’s GPS tracking of the hike:
We choose to head up Mt Major along the Boulder Loop Trail (orange blazed). The trail started out as a casual walk in the woods, before gradually transforming into rocky terrain (p3-5 below), as its name suggested. The “boulder” section wasn’t technical, I would rate that as somewhere around YDS class 1.5. There were a few muddy spots (p6), but the condition was overall favorable.

On our way up, we encountered a few scattered raindrops (chances of rain were in the forecast), but luckily they ceased once we reached the top of Mount Major, where a magnificent panorama of Lake Winnipesaukee unfurled in front of us. The shape of Lake Winnipesaukee offered a vista of more than 180-degree of it from Mt Major, a view so broad to confine in one frame: it’s almost as if the lake was encompassing the mountain. The few islands dotting its surface resembled delicate ornaments on a ribbon of water, donned by the majestic backdrop of misty White Mountains.

From Mt Major, I launched my drone for an aerial tour of both Mt Major and Lake Winnipesaukee that complemented the views. Here’s a video:

It was a windy day, as my drone flew against the headwind back from Lake Winnipesaukee. For a moment, it gave me warnings that it may not make it back due to the headwind (despite that was in my consideration and I left it ample reserve battery). It turned out to be a false alarm, and it returned with some juice to spare.
After that, we decided to start our descent, for which we had two options, the more direct Mt Major Trail (blue) to the north, and the slightly longer Brook Trail (yellow) to the west. At that moment, my friend was feeling tired and hence looking for the fastest way off the mountain, which to him meant the direct Mt Major Trail, despite it would be steeper and rockier.
It turned out that the top of Mt Major Trail came with an encore of the views of Lake Winnipesaukee. However, the pleasing views soon gave way to a section of trail made of wet rocks, requiring meticulous navigation.
There I was overwhelmed by a swarm of bugs. It being the month of May, I anticipated their presence, for which I armed myself with a “shower” of DEET before leaving the parking area. My aromatic armament had kept the them mostly somewhat at bay, but was eventually outmatched by their sheer multitude here, relegating me to frantically waving my arms all over my head to disperse them, knowing full well that any pause would invite their immediate return. This aerial defense, however necessary, diverted my attention from the crucial task of finding secure footing on the slippery terrain.
Fortunately, I noticed a different path to the right/east, which turned out to be the “Ledge Detour” as marked on maps. It’s as steep, but provided better traction while I was busy fending off an insect invasion.
After leaving the insect-infested area, I found myself—being something of an AI enthusiast—formulating what I call the “soft-max bug attractiveness theorem.” This theory proposes that each person possesses a certain “attractiveness” to insects, where the distribution of bugs follows a soft-max function of everyone’s relative appeal within a certain proximity. I developed this hypothesis upon noticing that with my jacket off, my companions, who applied less DEET repellent than I, were more attractive to the bugs, but with my jacket on obscuring the repellent, I became their target.
Upon sharing this observation with my colleagues in AI research, they contributed several nuanced refinements. They suggested that individual insects should be assigned “temperature” parameters to differentiate between the single-minded pursuers and their more casually wandering counterparts. The theory soon evolved into a more sophisticated model where both humans and insects would possess vector embeddings, elegantly accounting for the asymmetrical nature of this peculiar form of “attention.”

Apart from the bugs, the descent wasn’t remarkable. We got back to the parking lot at 1:20pm, by which time it was a lot emptier. After that, we drove back home and concluded the day.
