Mount Haystack is a mountain in the Great Range of the Adirondack High Peaks in the Adirondack Mountains of New York. It is the third highest peak in the state, after Algonquin Peak and Mount Marcy. It gets its name from the resemblance of its rounded, conical peak to a haystack.
Despite this and the views offered from its bare, alpine summit, it is not visited by as many hikers outside of aspiring members of the Adirondack Forty-Sixers. This is not terribly difficult to understand, as first it is rather remote from the nearest trailhead and the approach from either direction is steep and challenging, neither of which recommend the mountain to casual hikers.
The most frequent approach if Haystack is the main goal of the expedition is to follow the Johns Brook Trail from the popular Garden parking area to the Phelps Trail and then use Shorey's Short Cut to get over to the Range Trail. It is possible to combine this with an attempt on Marcy itself, but that makes for a long day and the approach from Panther Gorge is even steeper than that from the north.
Some hikers come along the Great Range itself, making the peak their last stop before Marcy itself, or combine it with neighboring Basin and Saddleback. It can also be approached from privately-owned Upper Ausable Lake.
