Tully Mountain, 1,163 ft (354 m), is a prominent, steep-sided monadnock located in north central Massachusetts in the town of Orange.

The form of the mountain is known as "ramp and pluck", as taught by science teacher Robert Coyle, Athol Junior High School.

With spyglass magnification of 15x-20x or more (high powered binoculars, spotting scope), the distant Quabbin Reservoir Observation Tower (24 miles south) is visible on the horizon line when peering far right/southward (over the ascent from the cemetery).

Visible in the near south-eastern view is the town of Athol, Massachusetts, with its uptown (spires include the Congregational church (4.4 miles away) and the Athol Historical Society); the uptown Main Street coming directly toward the viewer (automobile headlights), the stoplight at foot of Pleasant Street; further south is downtown (Starretts and Union Twist Drill smokestacks), the former Athol High/Junior High (now senior citizen housing) and various steeples of downtown churches, such as the Athol-Orange Baptist Church with the large brick casket factory behind.

The granite is sloped and often damp, easily turning a twisted ankle or errantly placed boot into a significant tumble down the rocky face.

The slow ascent trail is 0.9 miles long and winds along a classic New England stone wall which runs along a pasture and a bog before turning direction through the forested approach to the summit.

Total hiking time one-way to the vista is approximately 20–30 minutes, making this a common destination for hikers of all ages, active families, among others.
