Short bike and walk to a place where I was young and innocent. Spent decades out here on four wheelers and hiking.

The northern section of the Air Line Trail is particularly captivating, featuring an old bridge and the intriguing "Hermit Cave," and culminating at the tri-point marker where Connecticut, Massachusetts, and Rhode Island meet. This boundary is identified by a 4-foot granite monument (with an additional 5 feet underground) situated in a small hilltop clearing. The marker, 14 inches square with a 6-inch pyramidal top, is inscribed with "MASS 1883" on the north side, "R.I. 1883" on the south, and "CONN" on the west—Connecticut's side lacks a date due to disagreements over the boundary. This monument was installed by a commission from Massachusetts and Rhode Island in late 1883.

The Quaddick Reservoir, spanning over 400 acres, is a man-made body of water that was once frequented by the Nipmuck Indians for fishing. It was formed by damming the Five Mile River. During the fall, this area becomes stunning as the trees change colors.

As you make your way across the bridge you will see Grosvenordale Mills located on the banks of the French River. It's a nice place for a stop!

At Cargill Falls, you'll find a dam and cascades right in the heart of the city. From the Pomfret Bridge on US-44, you can see the wide dam and several flowing channels clearly. An island splits the Quinebaug River and the dam, creating a beautiful display of cascades below as the river rushes to reconnect.
