This trail is 2.7 miles along a beautiful stream. The full trail is 5.2 miles long, between Round Pond and the East Mill Flow trailheads. This is west of Round Pound with gentle changes in elevation, many footbridges, and wonderful views of Schroon Brook alongside most of the trail. Midway it crosses East Mill Brook.
Hikers using the East Mill Flow Trailhead are required to pay a day use fee when the campground is open. See the trailhead location with this Google map link. There's also the Round Pond trailhead on Ensign Road.
