Metacomet - Monadnock Trail

The Metacomet-Monadnock Trail is a 183 km (114-mile) point-to-point trail in the United States, running from the Massachusetts–Connecticut border north to the 965 m (3,165 ft) summit of Mount Monadnock, New Hampshire. It accumulates roughly 2,800 m of elevation gain over an estimated 7–10 hiking days. Rated moderate to challenging, it threads basalt ridgelines, river valleys, and upland forests across one of New England’s most geologically varied landscapes.

About the Metacomet - Monadnock Trail

The Metacomet-Monadnock Trail — popularly called the M&M Trail — is one of New England’s longest continuous footpaths, stretching 183 km (114 miles) from Rising Corner Road in Southwick, Massachusetts, through the Pioneer Valley and central Massachusetts uplands, to the bare granite summit of Mount Monadnock (965 m) in southern New Hampshire. The route links two distinct geological personalities: the southern 40-mile (64 km) section traverses the Metacomet Ridge, a volcanic trap-rock escarpment formed from ancient Mesozoic basalt flows, while the northern 66-mile (106 km) section follows an elevated metamorphic rock plateau averaging around 300 m above sea level.

The trail was conceived in the 1950s by Professor Walter M. Banfield, who designed it as a northern extension of Connecticut’s existing Metacomet Trail, stitching together newly blazed footpaths, abandoned farm roads, and established hiking routes into a single through-route. Today it is maintained by the Berkshire Chapter of the Appalachian Mountain Club (AMC), which coordinates volunteer trail work across Hampden, Hampshire, Franklin, and Worcester counties in Massachusetts, and Cheshire County in New Hampshire. The trail crosses a mix of public lands, conservation easements, and private property held open by landowner courtesy.

The terrain alternates dramatically along the route. Trap-rock ridgelines in the south offer sweeping views west into the Berkshires and east across the Pioneer Valley. Crossing the Connecticut River floodplain near Northfield, the trail drops to just 27 m above sea level before climbing again through hardwood forests toward the New Hampshire border. Communities along the route include Agawam, Westfield, Holyoke, Northampton, Amherst, and Northfield in Massachusetts, and Richmond, Fitzwilliam, Troy, and Jaffrey in New Hampshire — all offering resupply and accommodation options.

Route Overview & Stages

Most through-hikers complete the M&M Trail in 7–10 days, averaging 18–26 km per day. The trail is marked with blue rectangular blazes throughout, with white blazes where it coincides with other named routes. Westfield, Northampton, and Northfield are the three main resupply towns and naturally divide the route into manageable blocks. Below is a practical stage breakdown from south to north.

Highlights & Points of Interest

• Metacomet Ridge Bluffs (Southwick–Westfield): The trail opens on volcanic trap-rock escarpments created by Mesozoic lava flows, offering cliff-edge views across the Hampden County farmland below. The layered basalt columns — shared geologically with Connecticut’s Metacomet Trail directly to the south — are among the most distinctive rock formations in western Massachusetts.
• Mount Tom (367 m): The crown of Mount Tom State Reservation, this summit delivers some of the finest Connecticut River Valley panoramas on the entire route. The west face drops 330 m to the valley floor, creating the most dramatic single viewpoint of the southern section.
• Holyoke Range & Seven Sisters: A string of east–west trap-rock peaks crossing Holyoke Range State Park, the “Seven Sisters” ridgeline demands a series of short, sharp climbs between each saddle and rewards with expansive views toward the Pioneer Valley college towns of Amherst and Northampton.
• Skinner State Park & Summit House: Home to the historic Summit House (built 1821) atop Mount Holyoke, this park is one of the oldest mountaintop recreation areas in the United States. The landscape inspired Hudson River School painter Thomas Cole and remains a landmark of New England cultural history.
• Connecticut River Corridor (Northfield): At its lowest point — just 27 m above sea level — the trail crosses the Connecticut River near Northfield, offering flat, pastoral walking through river meadows and wetland floodplain before the long climb into the central uplands resumes.
• Royalston Falls: An 18 m (60 ft) plunge waterfall on the Tully River watershed, Royalston Falls is one of the most dramatic cascades in Massachusetts. The surrounding old-growth hemlocks and sandstone ravine make it the natural showpiece of the trail’s northern segment.
• Rhododendron State Park (Fitzwilliam, NH): Just before the final summit push, hikers pass through the largest natural stand of Rhododendron maximum in New England — a grove of shrubs 3–5 m tall that erupts in pink-white blooms in mid-July. The cathedral-like canopy creates a striking setting in every season.
• Mount Monadnock Summit (965 m): The trail’s northern terminus on this bare granite dome is the defining moment of the journey. One of the most-climbed mountains in the world, the summit commands 360-degree views reaching all six New England states on a clear day — the ultimate reward for 183 km of walking.

Best Time to Hike the Metacomet - Monadnock Trail

The M&M Trail is hikeable from late April through October, but the window from mid-May to mid-October offers the best combination of passable conditions, reliable water sources, and clear summit views. As of 2026, trail conditions reports from the AMC Berkshire Chapter confirm that snowpack typically clears from the lower sections by late April, though Mount Monadnock can hold icy patches into early May.

May and June offer excellent hiking: daytime temperatures range from 12–22 °C, streams run full from spring snowmelt, and the hardwood canopy is just leafing out, keeping ridge sightlines open. This is peak season for wildflowers in the Royalston Falls ravine and native azaleas on lower slopes.

July and August are popular but demand early starts. Temperatures on open ridgelines reach 28–32 °C by midday, and the exposed summit of Mount Monadnock is particularly vulnerable to fast-moving afternoon thunderstorms. Beginning the summit section before 07:00 is strongly advisable in high summer.

September is the single best month to hike the Metacomet-Monadnock Trail. Temperatures cool to 10–20 °C, tick populations thin significantly after the first frosts, and autumn foliage peaks in the third week of September across the central Massachusetts uplands. Summit visibility from Mount Monadnock is typically at its annual best, and trail towns are easier to book than in peak summer.

October remains viable for experienced hikers, though nights can drop below freezing above 600 m and some water sources may run low in the northern sections.

Practical Information

Accommodation

The M&M Trail has no network of purpose-built hiker huts. Most thru-hikers combine dispersed camping on state forest land with occasional stays in trail towns at three natural resupply stops.

• Primitive camping (Massachusetts state forests): Free to approximately €5/night on most state forest land with a free MassParks dispersed camping permit, registered online before departure.
• Mount Monadnock State Park Campground (Jaffrey, NH): The main campground near the northern terminus charges approximately €21 (US $23) per tent site per night. Flush toilets and water are provided on-site. Advance reservations are recommended from July through September.
• Northampton / Amherst area (Stage 3 resupply): Budget rooms in Northampton run €40–65/night; the Five College area offers seasonal hostel-style accommodation at approximately €32–45/night.
• Northfield B&Bs (Stage 4 rest stop): Several small B&Bs in Northfield charge €70–110/night and sit within 3 km of the trail, making them ideal for a mid-hike rest day before the northern upland push.

Getting There & Back

Southern trailhead (Southwick, MA): Bradley International Airport (BDL) in Windsor Locks, Connecticut, is approximately 40 km (25 miles) south — about 35 minutes by car. Amtrak’s Lake Shore Limited stops at Springfield, MA, 14 km northeast of Southwick; a rideshare covers the remaining distance. Pioneer Valley Transit Authority (PVTA) buses connect Springfield to Agawam, within 5 km of the trailhead on Rising Corner Road.

Northern trailhead (Mount Monadnock, NH): The trail finishes at the Monadnock State Park trailhead in Jaffrey, NH. Manchester-Boston Regional Airport (MHT) is 80 km (50 miles) northeast — approximately 1 hour by car. Boston Logan International Airport (BOS) is 145 km (90 miles) east, roughly 1 hour 45 minutes in normal traffic. No regular public transport serves Jaffrey directly; book a shuttle through a Keene, NH outfitter or arrange a private transfer.

For a full point-to-point thru-hike, leaving a vehicle at each terminus or booking a commercial hiker shuttle between Southwick and Jaffrey is the most practical arrangement. Several Northampton-area outfitters coordinate M&M Trail shuttles; ask locally for current providers.

Permits & Fees

No single end-to-end permit is required for the Metacomet-Monadnock Trail. Key fees and registrations to plan for:

• Massachusetts state forest camping: A free dispersed camping permit is required for overnight stays on state forest land; register through the MassParks online portal before your trip.
• Mount Monadnock State Park day-use fee: Approximately €7 (US $8) per adult is charged at the Monadnock State Park visitor centre in Jaffrey for access to the state park section at the northern terminus. Children aged 11 and under are free; New Hampshire residents pay a reduced rate.
• Private land sections: Roughly 10–15% of the trail crosses private property through courtesy agreements. Stay strictly on the blue-blazed route; camping off-trail on private land without explicit landowner consent is not permitted and risks jeopardising access for all future hikers.

Gear & Packing List

The M&M Trail’s 183 km over 7–10 days demands a capable multi-day pack — large enough for food carries of 3–4 days between resupply towns, yet light enough for the trap-rock ridgeline scrambles and the steep Mount Tom and Monadnock ascents. Before heading out, read our guide on how many calories you need hiking a full day to plan your food load accurately for a multi-day carry.

• Pack (40–55 L): An ultralight frameless or semi-frameless pack suits thru-hikers keeping base weight under 5 kg. The Hyperlite Mountain Gear 2400 Windrider (40 L, 510 g) is ideal for minimal-weight setups. For higher food volumes on the longer carries, the Zpacks Arc Haul Ultra 50L adds capacity without sacrificing much weight. Hikers preferring a traditional frame for shoulder-season cold-weather loads will find the Osprey Aether 65 handles heavy carries comfortably. Full comparisons are in our best ultralight backpacks 2026 round-up.
• Footwear: Lightweight trail runners handle the southern sections and valley stages well. Stiffer boots with ankle support are preferred on the rocky trap-rock bluffs of the Metacomet Ridge and the Mount Monadnock summit scramble, particularly in wet conditions.
• Tick protection: Deer ticks carrying Lyme disease are a significant hazard across all low-elevation sections from April through October. Treat clothing and gear with permethrin before your trip and conduct daily full-body skin checks throughout — this is not optional on the M&M Trail.
• Water treatment: Water sources are generally reliable but can run low in late August in the Stage 5 northern uplands. Carry a filter or UV treatment device; never rely on untreated water in the deer-populated forests of western Massachusetts.
• Rain gear and insulation: Mount Monadnock (965 m) experiences rapid weather changes in all seasons. A 3-layer waterproof shell and an insulating mid-layer are non-negotiable for the summit approach regardless of the forecast.
• Navigation: Download offline maps (Gaia GPS covers the full route with the blue-blazed M&M overlay) and carry a waterproof paper backup. Mobile coverage is poor through the Stage 4–5 central uplands.

Frequently Asked Questions

When is the best time to hike the Metacomet-Monadnock Trail?

September is the best single month to hike the M&M Trail. Temperatures are comfortable (10–20 °C), autumn foliage peaks across central Massachusetts, tick populations are lower than in summer, and summit views from Mount Monadnock are typically at their clearest. The trail is hikeable from late April through October, but summer hikers should begin each day early to avoid afternoon thunderstorms on the exposed ridgelines and summit.

How difficult is the Metacomet-Monadnock Trail?

The trail rates overall moderate to challenging. The southern Metacomet Ridge sections involve short, steep scrambles on basalt bluffs with no sustained technical climbing. The central valley stages are relatively flat and straightforward. The final approach to Mount Monadnock (965 m) is the most demanding segment — the summit cone is rocky and exposed, treacherous in rain or ice. Allow extra time and take care on the Monadnock section.

How many kilometres should I plan per day?

Most hikers cover 18–26 km (11–16 miles) per day over 7–10 days. A comfortable pace for fit backpackers is around 22 km per day, allowing adequate time for rocky ridgeline sections. Budget a shorter day for Stage 6 to the Mount Monadnock summit. The three main resupply towns — Westfield, Northampton, and Northfield — naturally divide the route into manageable blocks.

Where do hikers sleep along the route?

Accommodation is a mix of dispersed camping on Massachusetts state forest land (free with a MassParks permit), the Mount Monadnock State Park campground (approximately €21/night) near the northern terminus, and budget lodging in trail towns. Northampton and Northfield both have B&Bs and inns within a few kilometres of the trail. There are no purpose-built hiker huts on the M&M Trail; carry a tent or tarp for all forest sections.

Do I need a permit to hike the Metacomet-Monadnock Trail?

No through-hiking permit covers the entire route. Day visitors to Mount Monadnock State Park pay approximately €7 (US $8) per adult. If you plan to camp on Massachusetts state forest land, register for a free dispersed camping permit via the MassParks online portal before your trip. Stay strictly on the blue-blazed trail where it crosses private land — access depends on courtesy agreements, and straying off-route can jeopardise access for future hikers.
