Much of the mountain is located within Miller State Park. A seasonal automobile road ascends from the south to a picnic area at the summit. The summit also has a staffed air-pollution monitoring station.

The east side of the mountain drains into the Souhegan River watershed, thence into the Merrimack River and Atlantic Ocean; the west side drains into the Contoocook River, thence into the Merrimack River.

The mountain is the home of the Pack Monadnock Raptor Migration Observatory, where birdwatchers from around the region gather for the annual hawk migration. During the peak migration season in September, birdwatchers search the sky for kettles of hundreds of hawks swarming above rising thermals as they migrate south.

The mountain's summit at Peterborough is also home to the transmitter of two Manchester-market radio stations: NOAA Weather Radio station WNG575 and 92.1 WDER-FM, which airs a Christian talk and preaching format.
