Visiting the Hawk Watch

Plan Your Visit

Visitors are most welcome at the Pack Monadnock Raptor Observatory! Here’s what you need to know to plan your trip:

Dates & Timing

Weather permitting, the Observatory is staffed every day from Sept. 1 through Nov. 15. Peak hawk migration runs from mid-September through mid-October, but raptors move through in the early- and late-season as well. The migration is most pronounced on northwest winds, especially on the several days following the passage of a cold front.

Location & Parking

The Pack Monadnock Raptor Observatory is located within Miller State Park, near the summit of Pack Monadnock Mountain in Peterborough, NH. Access is via Miller Park Road, off Route 101. The closest parking is the small lot at the summit of Pack Monadnock (0.2 miles from the Observatory platform), though this lot often fills early on weekends in September and October. Visitors can also park in the large lot at the base of the mountain, and hike to the summit via the Auto Road (1.3 miles one-way), the Marion Davis Trail (1.4 miles one-way), or the Wapack Trail (approx. 1.6 miles one-way).


There is no fee to visit the Observatory, but there is a fee to enter Miller State Park: $4 per adult and $2 for children age 6 to 11. Children age 5 and under, and NH residents 65 and older, are free. For more information on entrance fees, trails, and other park details, visit the Miller State Park website.


The observation area and 0.2-mile trail from the summit parking area to the Observatory are both ADA-accessible.


The Observatory is open to the public, but reservations are required for large groups. If you’d like to bring a group to the Hawk Watch, please contact Miller State Park (603-924-3672) in advance to avoid scheduling conflicts. The earlier, the better!
