From the trailhead, follow the "big pine" trail markers. The trail follows a short downhill and cross a small brook. After a small climb, the trail reaches a junction. The trail to the left travels 0.25 miles to the shores of Cranberry Lake. The trail to the right reaches the Big Pine in 0.1 miles. The Big Pine is more than 4.5 feet in diameter, more than 140 feet tall, and is one of the largest virgin white pine trees in the Adirondack Park. 0.2 miles past the Big Pine, the trail ends at a floating bog with excellent wildlife viewing opportunities.
View the big pine from a distance as to not damage the roots or bark, which is estimated to be over 300 years old.
The Big Pine Trail is on land maintained by the New York State Department of Environmental Conservation as part of the Five Ponds Wilderness.
The Big Pine Trailhead can be tough to locate but is used frequently. This unmarked trailhead is located on the right side of South Shore Road just over 1.5 miles after the bridge over the Oswegatchie River. South Shore Road ends just past the trailhead and a small pull off on the right can be used as a landmark for finding the trail. In winter, look for snowshoe and ski tracks entering the woods on the right side of the road.
