There are three branches of Trout Brook. The North Branch simply flows between Warrens Pond and Big Marsh; the Hoffman Notch Trail follows much of its length. The trailhead is located along County Highway 2b (the Boreas or Blue Ridge Road).
The east and west branch meet farther south and flow along Trout Brook Road, just west of the town of Schroon Lake. Check for access along the length of Trout Brook Road. The state is scheduled to stock 1,300 yearling brook trout in the stream as it flows through the town of Minerva.
Access via Hoffman Notch Trail.
