Jul 5, 2025 — The Seward group is a cluster of four 46ers set farther west from the other Adirondack High Peaks. They offer less in terms of views, and the somewhat long, boring approach to their base makes them a less appealing objective than many others. Seward Mountain is the gem of this group, both the tallest and most prominent. Donaldson Mountain and Mount Emmons are just two lumps along the ridgeline, unranked peaks feel like questionable additions to the Adirondack 46ers list. Seymour Mountain sits on its own and is often hiked separately from its Seward Range siblings, but I wasn’t about to do the long approach twice, so I just grouped them all together.

I chose a clockwise route so I could get the long, flat old-road walk out of the way first, starting with Seymour Mountain. I began along the Blueberry Trail from the parking area, which was essentially an old road repurposed as a hiking trail. There’s also an equestrian-designated trail paralleling it to the south, clearly marked with signs to keep hikers on track. Past its junction with the equestrian trail, the Blueberry Trail becomes the Ward Brook Truck Trail, which is a long, flat stretch of old road walking. It stayed mostly level for several miles, making for an easy warm-up but not a particularly thrilling one, as it headed toward the northern base of the peaks.

I passed the herd path junction for the Mount Seward Trail, first continuing farther to tackle Seymour Mountain since it’s an out-and-back. Seymour is a typical Adirondack peak hike, complete with boulders everywhere, roots plotting ankle traps, and a couple of scrambles to keep things interesting. Slabs appeared here and there, the kind that look harmless but turn into slides when wet. Higher up, the scenery grew more lush, with moss carpeting the rocks. Seymour’s summit itself wasn’t memorable, so I didn’t linger before heading back down.

Back at the Seward Mountain Trail, the route soon paralleled a creek, with little cascades here and there. The trail mixed in bouldery sections, a few scrambles, and some messy downed trees covering muddy ground. Near the summit, a short cliff forced a detour along its base before a hairpin turn brought me up.

From the top of Seward, I could see the remaining two 46ers along the ridge. The descent was steep, and the trail veered well off the ridge crest, adding unnecessary vertical gain, and I wondered why it wasn’t built to just stick to the crest. The high-elevation forest here was beautiful, so a little extra effort didn’t hurt.

I reached the junction with the Calkins Brook Trail, but first, I needed to tag the other two peaks. A short spur brought me up a few scrambles to Donaldson Mountain, an unremarkable summit. Next, there’s a short descent into a col before the climb up to Mount Emmons, where a series of infamous mud pits began. Mount Emmons feels like the unnecessary side quest of the 46ers: lost in mud and trees, almost invisible on the map, and offering virtually no views. Plus, its low prominence keeps it far from meeting my personal peakbagging rules, placing it near the bottom of my 46er favorites list. I guess it was a quick enough out-and-back, though.

I retraced my steps over Donaldson and picked up the Calkins Brook Trail for my descent, which would allow me to complete the loop. This route down was notably less steep than the ascent to Seward and far less rocky, mostly just forest walking with a few creek crossings. The afternoon light was lovely and I really enjoyed the long walk back. Eventually, the trail crossed Calkins Brook and widened into old doubletrack, meeting the Calkins Brook Truck Trail. It climbed a few hundred feet over a pass (err… “col”, I guess, since this is the northeast) before dropping me back onto the Blueberry Trail, closing out a full day of classic Adirondack shenanigans.
