Lyon Mountain, at 3830 feet, is the highest point in Clinton County.  It is located in the northeastern part of Adirondack Park, west of Plattsburgh, NY.  There is the old 2.5 mile trail that leads to its summit and fire tower.  The old trail has an overall elevation gain of 1900 feet over the 2.5 miles and is very eroded in many places.  There is a lot of hiking on bowling ball size rocks.

There is a new trail that was created a couple of years ago that takes a more winding route up the mountain for a total of 3.4 miles.  Many hikers now take the new trail up and the old trail down for a overall hike of 5.9 miles.

You are rewarded with a 360 degree view from the fire tower.  Views all the way to Montreal to the north, the Green Mountains and Vermont to the East and the high peaks to the south.

Below are maps of the old trail and one map of the new trail (if anyone has the new trail gps'd, please e-mail the tracks to me). 

Directions:  To get to the trailhead from I-87 take Exit 38N, take NY 374 west 23.2 miles to Chazy Lake Road (County Route 8). Drive south 1.8 miles on Chazy Lake Road to an unnamed gravel road on the right (called Lowenburg Road at one time). At the beginning of the gravel road is a black and white sign indicating it is a seasonal, limited-use highway with no maintenance from Nov. 1 – May 1. Follow the gravel road about a mile to the parking area.
