Anna Mountain sits in the southern Belknap Range at 1,670 feet, straddling the Gilmanton-Alton town line and largely within the Griswold Scout Reservation. The wooded summit offers no views of its own, but a short detour southwest along the Blue Trail reaches a ledgy outlook with pleasant south and west-facing perspectives.
The most direct approach follows the Red Trail departing north from Old Stage Road, climbing about 770 feet over a mile of at-times steep and rocky terrain to the summit in roughly an hour. For something more varied, the Precipice Path traverses the southwest flank of neighboring Straightback Mountain on its way to Anna, linking a cascading stream, a waterfall, and a cautious 300-yard walk across the top of a cliff face up to 90 feet high; care is essential in wet conditions. Anna is also commonly reached via longer loops that take in Straightback Mountain or descend to Round Pond.
The Belknap Range is hikeable year-round at these modest elevations, though ice and snow can make the rocky pitches and cliff traverse on the Precipice Path treacherous in winter. Spring mud season slows travel on the lower sections. The area is lightly traveled compared to the White Mountains, making it a good option when higher peaks are socked in.
