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.

This granite monument marks the border of Connecticut, Massachusetts and Rhode Island. It was set over 130 years ago. The mountain bike trails in the area are great too.

There is a great view here from the King Phillip's Trail toward Goat Hill and down onto the Rice City Pond section of the Blackstone River. There are a bunch of trails over on Goat Hill that offer a different perspective of the water and valley.
