The Wapack Trail is a 21-mile ridgeline route connecting Mount Watatic in Massachusetts to North Pack Monadnock in New Hampshire, and one of America's oldest interstate hiking paths, completed in 1923. It follows a chain of modest summits with views stretching from Boston to Vermont's Green Mountains. Despite the short length, the trail packs 4,500+ feet of elevation gain into constant ups and downs over rocky ledges, hardwood forests, and exposed ridgelines.
This trail suits backpackers looking for a quick overnight or winter training trip close to New England's population centers. The low mileage, proximity to civilization, and single legal camping area keep logistics straightforward, though you will need to reserve shelter space months ahead during peak season. The rules are stricter than on wilderness trails, but in exchange you get exceptional fall foliage, winter accessibility, and historic New England character.
No permits are required for hiking the Wapack Trail. However, Miller State Park charges a $4 day-use fee (paid at a trailside fee box) where the trail crosses the auto road to Pack Monadnock summit. Children under 12 pay $2.
Camping and campfires are prohibited everywhere except at Windblown Cross-Country Ski Area's four primitive shelters, located near the trail's midpoint in New Ipswich, NH. Much of the trail crosses private land under conservation easement, so this camping restriction is absolute. Violators risk losing the landowner cooperation that keeps the trail open. Windblown camping operates April through November (no winter use). Reserve shelters via email at alwindblown@gmail.com or phone (603) 878-2869. Rentals are private, one group per shelter. Fees are approximately $5 per person per night. Book early for fall weekends.
All dogs must be leashed on the entire trail, especially within Wapack National Wildlife Refuge, Miller State Park, Temple Mountain State Reservation, and Binney Pond Natural Area. Hunting, fishing, and trapping are prohibited within the wildlife refuge sections.
April through November has the most reliable conditions, though the trail stays open year-round. September and early October bring peak fall foliage and comfortable temperatures. This is the most popular window; expect crowds on weekends and book Windblown shelters months in advance.
Late May through early June has flowing water sources and spring wildflowers, but mud season lingers through late May and leaves the trails slippery and root-covered. Black flies peak during this period. Wait until late May for drier footing.
July and August bring the longest days and warmest weather, good for finishing the trail in a single push. Water becomes critically scarce, though: every stream may run dry except Binney Pond and its nearby spring. Afternoon thunderstorms build quickly, so plan to leave exposed ridges by early afternoon.
December through March turns the Wapack into a winter backpacking training ground. With low mileage and roads nearby, it works well for cold-weather beginners. After snowfall, expect to use microspikes or crampons on icy ledges, carry insulated water bottles, and navigate snow-covered ridges. Temperatures regularly drop below zero, and windchill adds another 10-20 degrees of cold on exposed summits. Snow can fall as late as May and as early as October.
Water is the Wapack's most serious logistical challenge, and seasonal reliability varies dramatically:
Northbound (MA to NH): Water is scarce for the first 10 miles. Small streams often run completely dry from July through fall. The first reliable source is the Binney Pond area (approximately 18 miles from the southern terminus), which has a nearby spring. All water requires filtration.
Southbound (NH to MA): The northern 10 miles have better water availability, but the southern sections dry up by summer. Again, Binney Pond is the most dependable source.
Windblown Shelters: Water is available for overnight guests, but the walk from the shelters to the source is roughly half a mile each way. Plan your arrival accordingly.
Summer/Fall Strategy: Carry capacity for long, dry stretches, potentially 10+ miles between sources. Check recent trip reports before starting, since even "reliable" sources may surprise you.
At 21 miles, the trail needs no traditional resupply, but the trailhead towns work for pre-hike provisioning:
Peterborough, NH (northern access, 15 minutes from Miller State Park): Full services, including Shaw's supermarket, Roy's Market, Nature's Green Grocer (natural foods), outdoor shops, and restaurants. The best option for stocking up.
Ashburnham, MA (southern terminus): Limited services, with a general store and restaurants. Smaller selection than Peterborough.
Temple, NH (mid-trail access): Minimal services. Do not rely on Temple for resupply.
The Wapack's modest elevation hides its physical demands. Constant elevation change totaling 4,500+ feet over 21 miles causes fatigue out of proportion to the distance. The rocky terrain requires vigilance; twisted ankles are common on root-covered descents and boulder scrambles, particularly on the steep northern section approaching North Pack Monadnock.
Exposed Ridgelines: Multiple open summits and ledges have wide views and zero protection from weather. Afternoon thunderstorms arrive quickly; watch conditions and descend from ridges by early afternoon during summer. In winter, windchill on exposed peaks drops temperatures 10-20 degrees below valley readings. Temperature decreases 3-5 degrees per 1,000 feet of elevation gain.
Navigation: Trail blazing is generally good, but winter conditions bury markers under snow. Routefinding skills and a map are essential for snow-covered ridge traverses.
Wildlife: The trail passes through Wapack National Wildlife Refuge, home to black bears, moose, white-tailed deer, coyotes, bobcats, and fishers. Practice proper food storage at the Windblown shelters. Black flies peak in late May and early June. No venomous snakes are documented on this trail; the milk snakes, garter snakes, and ribbon snakes you may see are harmless.
Limited Camping: The single legal camping location creates a logistical chokepoint. If Windblown is full or closed, you cannot legally backpack the trail overnight. Always have a backup plan.
There are no significant river crossings on the Wapack Trail.
Northern Terminus (North Pack Monadnock - Greenfield, NH): From Route 31, take Russell Station Road (2.8 miles south of Route 136 in Greenfield center, or 8.1 miles north of Route 101 in Wilton). After 0.8 miles, turn right onto Mountain Road. The large parking area appears on the left in 1.9 miles. A short spur trail connects to the Wapack's northern terminus. Parking is free and open sunrise to sunset. No facilities.
Southern Terminus (Mount Watatic - Ashburnham, MA): Parking is off MA-119 in Ashburnham at the designated parking area (GPS: 42.696796, -71.904521). The limited spaces fill early on weekends; arrive before 9am or risk parking enforcement along MA-119, where roadside parking is strictly prohibited. Some overflow parking may be available across the street, but regulations change.
Mid-Trail Access (Miller State Park - Temple, NH): Parking is available off Route 101 at Miller State Park and Temple Mountain Reservation. Miller State Park charges day-use fees ($4 adults, $2 children) and has restrooms. Parking is limited on nice weekends and holidays; reservations are possible, with walk-in spaces available first-come, first-served. From the Route 101 parking area to Pack Monadnock summit via the Wapack Trail is 1.4 miles.
Nearest Airport: Manchester-Boston Regional Airport (MHT) is the closest major airport, approximately 45 minutes to the trailheads. Boston Logan International (BOS) is 90 minutes south.
Shuttle Services: No dedicated shuttle service exists for the Wapack Trail. You must arrange your own car shuttle between the termini or stash a bicycle at the endpoint. Some hikers coordinate vehicle swaps with other backpackers. The lack of commercial shuttles is the trail's biggest logistical frustration.
Most experienced hikers recommend hiking south to north (Ashburnham, MA to Greenfield, NH). This saves the trail's most scenic and demanding terrain, Pack Monadnock and North Pack Monadnock, for the second day, when you are warmed up and the morning light hits the northern summits.
Windblown has four shelters and two huts. The Warming Hut is particularly nice, with queen-sized bunks, a wood-burning stove, and a kitchen. Specify your preferred shelter when booking. Bring firewood if you want to use the stove, since gathering on-site may be restricted.
Do not skip the Joeanne Bass Bross Memorial Scenic Overlook spur trail near Pack Monadnock summit, or the Summit Loop viewpoints. At the top of Barrett Mountain, small ups and downs lead across the New Ipswich Mountains with open ridge scrambling across slab rock, some of the trail's best terrain.
In winter, this trail is a good introduction to cold-weather backpacking. Roads are always close by, which helps psychologically, and the 21-mile distance remains achievable even with winter's slower pace and heavier packs. Start with the Warming Hut's wood stove for confidence before attempting colder trips.
Water scarcity in summer cannot be overstated. Carry 3+ liters between sources and check recent trip reports on hiking forums before starting. A dry Binney Pond spring could force you to change plans entirely. The Pack Monadnock snack bar (currently closed seasonally) has a water spout that park staff test weekly. It can be a lifesaver if open, but do not count on it.
If you are day hiking sections rather than backpacking, the northern section from Miller State Park to North Pack Monadnock is the most scenic and demanding, while the southern section from Mount Watatic to Barrett Mountain has easier terrain with excellent early views of Mount Monadnock.
