The area around Hadley mountain has had a history of forest fires. There were several in the early part of the twentieth century. The mountain is still slowly recovering.

One thing you'll notice on this hike is the many patches of bare rock that begin early in the climb. This is due to the thin soils left by all the fires.

The only trail begins from the trailhead parking area next to an Historic Marker and begins an immediate climb. The hiking register is reached within a couple of dozen yards of leaving the trailhead. A moderate climb following red trail markers leads through woodland on a mostly bedrock trail. Crossing back and forth over a small creek (dry in summer), the trail continues steeply past interesting boulders and cliffs to a level shoulder at about 1.0 mile. Following this brief gentle section the trail steepens and continues mostly on bedrock to the summit.

The fire tower is open, but good views can be had without climbing it. The Great Sacandaga Lake is the body of water to the South.

Very icy & glad we had on minispikes as others were slip sliding down the trail. Cloudy day so no views but still things to see on our way up & down. Going up was tough for us as way out of shape!

It started out too foggy to see anything off the mountain, but luckily it lifted in the afternoon. The view turned out to be amazing.

Nice hike with rocky summit. There is a fire tower and ranger cabin. The view from the fire tower is wonderful.

Great hike! Went 11/8/2015, great weather (much better than the freezing fog of my first time in 2004). Great views, a little steep but quite do-able.
