Most direct route is the Pine Hill Trail which takes off from the Bicentennial Trail and features a granite step trail from bottom to the summit. On 28 NOV 25, route was initially dry, but a snow squall covered the trail and mountain with snow, making the descent a bit slippery in spots. However the beauty of this first snow of this winter made it wonderful.

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 foundations of belief on this property were based on Transcendentalist principles, but that social experiment failed in its first year of existence.
