This yellow marked trail starts from the popular Blue Mountain trailhead off NY 28/NY 30 and runs three miles to the Northville-Placid Trail then another 0.3 miles to the Tirrell Pond Lean To.  Most visitors to this trailhead are heading up to the fire tower on Blue Mountain so odds are good that you might have this trail to yourself.

From the north end of the parking area, the trail starts off on an old logging road but soon veers right. There is a bit of a climb in the beginning of the hike.  At 0.5 miles reach an open area.  The trail follows the side of Blue Mountain and crosses a private gravel road at 1.4 miles.

In a level area at 1.8 miles you cross the Hudson River - St Lawrence River drainage divide at an elevation of 2361 feet.  There are partial views of Blue Mountain to the south here.  Soon you'll begin a 400+ foot descent toward the Northville-Placid Trail. 

At 3.0 miles reach the famous Northville-Placid Trail.  The Tirrell Pond Trail ends at this junction.  To the left the N-P goes 9.6 miles north to Long Lake.  Turn right here and head 0.3 miles south to the junction of a yellow marked trail that leads to the Tirrell Pond Lean To.

Tirrell Pond is a very scenic location, however for those looking to take a dip in the pond beware of the reports of the possibility of leeches.  The N-P Trail continues south along the west shore of the pond and just over 1.1 miles is the new O'Neil Flow Lean To for those looking to explore more.
