Deerfield Ridge Trail from Haystack to Mount Snow is a 10.6 mile out and back trail located near Wilmington, Vermont that offers the chance to see wildlife. The trail is rated as difficult and primarily used for hiking and trail running.
Kbo Leth's review is perfect. We tried this about a month later and the rains of June made the bog at 0.3 miles before the Mount Snow complex insane. I was two small children and the bog was dangerous. It was like most mountain bogs I have seen we stuck towards the far left and hit tree roots. I missed one and sunk to my waist. The bog appeared to be about 200 to 300 yds long. We turned back this trail I have heard of people taking to ski on but that bog was not safe to travel. Will revisit it later in the year to make see if this is just seasonal due to the rain fall. There are no views and the scrub is horrible, the trail is barely used. The trail would be great if it was maintained, it is a great difficulty and the ridge portion is enough to make it worth the effort but no one uses it and so it is 20 times more difficult than it should be and a large section has been turned into a bog.
After the initial ascent, this is a relatively flat trail that has only one view and in May there were swarms of black flies and horseflies, making for a very lovely experience. As for the trail itself; The ascent up to Haystack peak is a very nice moderate climb and the reward is a fabulous view east across Vermont to New Hampshire. As you descend back down from the peak, at 0.3 miles, take a right at junction and continue northward, in approx 1 mile from Haystack peak you arrive at the top of The Hermitage ski area. This was uneventful except for a small bog which was easily diverted by sticking close to the boulders on the right side of the trail. The view from the top of the Hermitage ski area was much the same as from the peak of Haystack. Then the next 2.5 miles, from Haystack ski area to Mt. Snow was just a boring hike, with no views, on a path that was both unblazed and unmaintained, as there were several downed trees we had to make are way around. Although it was easy to follow where the path was leading, it was evident Deerfield Ridge Trail is rarely used past Hermitage. At approximately 0.3 miles before coming to the Big Dipper slope at the Sunbrook area of Mt. Snow we came upon a rather large bog that we both at times sank up to our knees. Stay clear of the middle and go way around into the area where there are tree roots to step on to keep you afloat. Not fun by any means. With wet feet and muddy legs we made it out to the slopes of Mt. Snow. As we were unsure if the main lift was running to take us down, we chose to hike across and then down the mountain as we had left a vehicle by the Summit hotel. The total mileage starting at Chimney Hill, up to the Haystack peak, then across the ridge and down to the Mt Snow base area, totaled out at 9.3 miles, 1511 ft ascent and 1667 ft descent.
