Yesterday, I hiked back to Dexter Lake, Spectacle Lake and Water Millspond in Ferris Lake Wild Forest, off of Hall Road and Seeley Road (which is off of Piseco-Powley Road). I could have driven Hall Road, it's not rough and there was plenty of parking as I was the only one there, but I often prefer to walk remote mountain roads to look at wildlife without having to worry about tripping on rocks.
It was about 15 miles round trip, via Hall Road - Dexter Lake Trail - Burnt Vly Trail - Water Millpond Loop, but it was well worth it as it was remote wilderness with many scenic views, including North Creek Falls which is rarely visited. I didn't see a single other person hiking for 5 hours.
