Climbing the Mount Redfield and Cliff Mountain via Calamity Brook Trail
From the Upper Works trailhead near Tahawus, New York, Cliff is trailless, reached via a herd path from the Flowed Lands and Uphill Brook area. True to its name, the route has steep, wet rock steps and short scrambles that are slick and awkward, especially descending. It is usually combined with Redfield deep in the interior, and the wooded summit has limited views. Remote with quick weather. Plan a very long day of 16-plus miles, start before dawn, and carry a map and headlamp.
