The trail begins at 1770 feet and ends at the junction of Greenleaf Trail and the Greenleaf Hut, 2.9 miles and 2430 feet above the starting point. The Old Bridle Path steadily climbs the western flank of Mt. Lafayette through a beautiful northern hardwood forest. At 1.9 miles, there are spectacular views east to Mt. Lafayette, Franconia Ridge, and Walker Ravine. (The cascading water heard from these ledges is Walker Brook.) As the Path ascends Agony Ridge, it passes through a spruce-fir forest. Sections of the trail are steep, rocky, and slippery when wet. To reach the summit of Mt. Lafayette, follow the Greenleaf Trail for 1.1 miles above the hut. Most of the Greenleaf Trail is above treeline as it ascends the cone of Mt. Lafayette.

There is no reliable water source between the trailhead and Greenleaf Hut.

Old Bridle Path served as a pony trail from the notch to the Old Summit House that once provided shelter for early climbers. Only the house's foundation remains.

Old Bridle Path has also provided a route up Mt. Lafayette for over a century. Mt. Lafayette, once known as Great Haystack, is the highest peak in the Franconia Range at 5260 feet. The peak is named after the French statesman and American Revolutionary War hero Marquis de Lafayette.

The Path ends at the Greenleaf Hut, operated by the Appalachian Mountain Club under a Special Use Permit issued by the USDA Forest Service. This backcountry facility offers meals and lodging to the public.
