#34 Seymour Mountain

#34 Seymour Mountain - Pure Adirondacks

Also part of the Seward Range, though not often climbed in conjunction with the other three mountains in the range, Seymour is a trail-less peak (doesn't have a maintained trail) that stands alone, separated by the other three in the range by a large valley. In terms of elevation, it ranks #34 among the Adirondack High Peaks. Despite its remote location and distance from the other Sewards, Seymour is a worthwhile climb, with many great views on the way to the top. The other peaks in the Seward Mountain Range (Seward | Donaldson | Emmons) are often hiked in one combined trip.

Trail Stats:
  • Distance: 14 miles round-trip
  • Elevation: 4,120 feet
  • Ascent: 2,355 feet

Given its remote location, one must begin hiking at the Corey’s Road Trailhead and hike on gradual terrain for about 5 miles to the Ward Brook Lean-To. Many choose to camp here and use it as a basecamp for summiting all four Sewards of the course of a couple days.

Once you reach the Ward Brook Lean-To, you will continue on approximately 500 feet to a brook where you will also see the herd path marked by a rock cairn heading up to your right. Continue along the herd path for about 0.5 miles until you come to an old slide. As you climb the slide be careful with loose rocks and pause to take in the views from the slide.

Be cautious as this route gets continuously steeper and getting your footing can be difficult, especially in slippery conditions (be extra careful on the descent). Soon the slide becomes too steep to continue along and the herd path will begin again off to your right. Continue along the herd path and soon the trail will come to a Y – if you follow it to the right, in 50 feet it will open up on a rock ledge with views of Upper Saranac Lake and Azure Mountain. If you take the Y to the left, you will continue on 100 feet to the summit of Seymour, which is in the trees.


Beginning in Saranac Lake, follow Route 3 towards Tupper Lake. Continue for around 13 miles to the turnoff for Corey’s Road on your left. Follow Corey’s Road for 5.5 miles until you reach the trailhead on your right.

Keep it PURE

Remember to Leave No Trace! Buy a physical map, read it, plan, and prepare. Think about the NYS Rangers and medical personnel that exhaust themselves for a rescue that could have been avoided. Pack out your trash. Use a bear canister when primitive camping and cook away from where you’re sleeping. Do the rock walk to help reduce the impact on fragile alpine vegetation. Camp at designated campsites and never camp on or near summits.

ADK Winter 46er Journey: Sam Perkins

I have learned so much over the years, and I continue to learn each time I go for a hike. I could go on and on about gear, trails, mountains, clothing, etc. A lot of it has been trial and error. I have spent a lot of time reading, looking at maps, learning more about weather, researching different gear… the list goes on.
