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 stone dam from the early 19th century provides a picturesque view of the Five Mile River and carries a rich history, once serving as part of a textile mill. This bridge point offers an excellent spot to appreciate the beauty of the surroundings.

The area is home to one of the earliest textile mills in Connecticut. Unfortunately, in 1861, the mill burned down, and it was never reconstructed. Numerous remnants of the mill, including a stone house situated on the corner, can still be found at the site.
