Grafton Notch State Park

Nestled within the rugged beauty of Maine’s Grafton Notch State Park, the Grafton Loop Trail (GLT) weaves through pristine wilderness, offering hikers a challenging yet rewarding experience. The beginning of this loop can be traced back to the collaborative efforts of various organizations, individuals, and entities.

The vision for this trail started with a collective aspiration to elevate Maine’s status as a premier hiking destination while conserving its natural landscapes. Historically, the Appalachian Trail served as the backbone of the region’s trekking paths. Emerging from this iconic trail is the Grafton Loop Trail, whose development began earnestly in the late 1990s.

The Maine Appalachian Trail Club, known for its stewardship of the Appalachian Trail in Maine, played a pivotal role in orchestrating the creation of the Loop. Their efforts were bolstered by the Appalachian Mountain Club, which recognized the trail’s potential to enhance the Appalachian range’s network of paths.

The conception and realization of the trail were also heavily influenced by the conservation initiative from the state’s Maine Outdoor Heritage Fund. They, along with the Maine Conservation Corps and the Maine Natural Areas Program, were instrumental in ensuring that the Grafton Loop Trail would not only serve adventurers but also protect and monitor the ecological integrity of the region. The conservation work within the designated Maine State Ecological Reserves was a cornerstone of this process.

Key agreements with several timber management companies, the contributions of other private landowners, and financial assistance from various private donors acted as an aggregate force that gave life to the trail.

In the early 2000s, the Appalachian Mountain Club (AMC), in partnership with the Maine Appalachian Trail Club (MATC) and the Appalachian Trail Conservancy (ATC), envisioned expanding the trail network in the region. Recognizing the potential for a spectacular loop, the idea for the Grafton Loop Trail was born.

In 2003, the Maine Outdoor Heritage Fund backed by the Maine Conservation Corps, injected crucial funding into the project. This financial boost, combined with support from private donors, enabled the acquisition of lands from private landowners and the realization of the trail’s development. This marked the fruition of a concerted effort spanning several years and involving a coalition of devoted nature advocates and organizations.

Over the years, the Maine State Ecological Reserves, the Appalachian Trail Conservancy, the Grafton Loop Trail Coalition, and the Maine Natural Areas Program’s involvement ensured that the trail’s construction and maintenance adhered to strict environmental standards. Timber management companies and private landowners played a pivotal role, allowing the trail to traverse through their lands and providing access to diverse ecosystems.

The Grafton Loop Trail officially opened in 2007, a testament to the collaborative spirit that brought it to life. Since then, it has become a haven for outdoor enthusiasts, attracting hikers eager to explore the splendors of the Maine wilderness.

Seasonal Considerations: Best Times to Hike and Weather Conditions

Grafton Notch State Park

The Grafton Loop Trail is best hiked during late spring, summer, and early fall (May to October). During this time, the trail offers ample water sources, comfortable temperatures, and moderate weather conditions. However, hikers should still be prepared for changing weather at higher elevations.

Here’s what to expect in each season:

Spring (March-May)

Spring on the Grafton Loop Trail ushers in milder temperatures that average from -1°C to 18°C (30°F to 65°F) as the snow begins to melt at the southern trailhead and along the lower elevations. This season is characterized by frequent rainfall and rapidly changing conditions.

The trails, notably around East Baldpate and the western part, can be wet and muddy. When heading south towards the parking lot at Miles Notch or the northern end, hikers should be prepared for lingering snow patches and icy conditions, especially at higher elevations such as Bald Mountain and the Sunday River White Cap.

Summer (June-August)

Summer at Grafton Notch State Park offers warm and comfortable hiking weather, with average temperatures ranging from 10°C to 27°C (50°F to 80°F). During these months, hikers can enjoy the full splendor of the trail, with open ledges offering expansive views and wildflowers in bloom.

When starting from the southern trailhead and covering the short distance to Stowe Mountain or West Peak, the lush green canopy provides respite from the sun. Hikers should note, however, that the weather can be unpredictable and afternoon thunderstorms are common, prompting the need for caution on exposed ridgelines like those around Sunday River Whitecap and East Baldpate.

Fall (September-November)

Autumn is a celebrated time for hiking the Grafton Loop Trail, with average temperatures ranging between -1°C and 21°C (30°F to 70°F). The changing foliage provides a spectacular backdrop for the trail, especially in the western part around Old Speck or the descent to the northern end of Grafton Notch State Park.

The southern trailhead and Sunday River Whitecap, however, experience mild daytime temperatures of 10°C to 20°C (50°F to 68°F), while higher elevations like Stowe Mountain in the western part may see cooler weather.

With clear skies, the weather generally remains stable, but temperatures can drop sharply after sunset. The Sunday River ski area, a short distance away, begins to prepare for the upcoming season, while campsites like those near the private land along the trail welcome fewer visitors.

Winter (December-February)

Winter on the trail brings a blanket of snow and a profound silence. Average temperatures can fluctuate from -5°C to -15°C (23°F to 5°F). The southern trailhead, near the Sunday River Ski Resort, signals the start of a winter wonderland, with thick snow often covering the trail up to West Peak and Miles Notch.

The trail, particularly in the eastern section towards East Baldpate, requires special winter gear to navigate safely. Higher elevations, including Bald Mountain, see more severe cold, providing a snowy haven for winter enthusiasts.

Hikers should be wary of harsh conditions, such as blizzards and freezing temperatures, when planning their trip and consider the daylight hours necessary to account for slower progress through the snow.

It is essential for hikers to check current weather conditions and forecasts from government sources, such as the National Weather Service, before setting out on their adventure.

Essential Gear and Equipment

  • Footwear: Opt for hiking boots or trail runners, depending on the season, ensuring comfort throughout the journey.
  • Clothing: Adopt the layering approach to deal with fluctuating temperatures. Start with moisture-wicking base layers, add insulating mid-layers such as fleece, and top it off with a waterproof and windproof shell jacket and pants.
  • Navigation: Though the Grafton Loop Trail is well-marked, a reliable map and compass are indispensable. In the digital age, a GPS device is also highly recommendable, and one should always ensure that devices are fully charged for optimal battery life. Backpack: Choose a backpack that suits the length of your hike. For day hikers, a smaller pack may suffice, but overnight treks will require a larger pack with compartments for food, water, and gear.
  • Shelter and Sleeping: For multi-day hikers, a lightweight tent or hammock, a sleeping bag rated for the lowest temperatures expected, and an insulated sleeping pad are crucial for restful nights in the wilderness.
  • Food and Water: Always carry an ample supply of water and remember to stay hydrated throughout the trek. Plan for nutritious, high-energy meals, such as trail mix and energy bars, to keep you fueled.
  • Emergency Supplies: In case of any unforeseen circumstances, bring a first-aid kit, a signaling device like a whistle or mirror, and an emergency shelter like an emergency blanket.
  • Bear Box: When camping, use bear boxes provided at designated campsites to store food securely.
  • Other Essentials: Other items that should not be forgotten include a headlamp or flashlight with extra batteries, sun protection like sunglasses and sunscreen, and trekking poles for added stability and support.

Remember to break in new gear before the hike and pack light to reduce strain on your body. For more tips on choosing the right gear for your next hiking trip, check out Silverlight’s hiking gear and hiking tips blog posts for expert advice and recommendations.

Itinerary: 2 Days along the Grafton Loop Trail

Grafton Notch State Park

Day 1: Puzzle Mountain to Stewart Campsite via East Peaks (21.1 miles, strenuous)

Kick off your trek at the southern trailhead, setting out early to conquer the formidable Puzzle Mountain. As you ascend, you will notice panoramic views of the Bear River Valley. Before reaching the mountain’s summit, take the right fork onto the Woodsum Spur trail for a scenic detour.

Continue to Stewart Campsite, navigating through the rolling terrain of Long Mountain and beside the tranquil waters of Chase Hill Brook. The path becomes increasingly rugged as it traces the border between Andover and Newry, discovering the path less traveled through private land. Your resolve is rewarded with a midday rest at Wight Brook.

With two campsites nestled approximately 1.3 miles (2.1 km) apart in this region, settle in for the night at either one after a thrilling segment of the journey. Set up your shelter under the East Peak of Baldpate and recharge for the next leg, where you’ll join the Appalachian Trail for a while before a smooth return to ME Route 26.

Select from the five designated campsites and revel in the seclusion they offer.

Day 2: A.T. Junction to Bear River via West Peaks (17.5 miles, strenuous)

After a restorative night, start west of ME Route 26 for a less traveled but equally exhilarating hike. Immediately delve along the A.T., with Cascade Brook. Climbing Old Speck unveils the rich forestry and wildlife, showcasing a dramatic view of Grafton Notch.

As you diverge from the A.T., the Grafton Loop heads south, where you’ll find a welcoming campsite approximately 2 miles (3.2 km) beyond Old Speck’s summit. Post-summit, your path spirals downward through Slide Mountain, leading to the serene Miles Notch. Climbing once more, the ascent to the Sunday River Whitecap infuses fresh energy into weary limbs.

From the heights of Whitecap, you will gradually descend to a campsite framed by the formidable Sargent Mountain, then sweep past Bald Mountain.

Finally, a carefully placed sequence of rock steps leads to a campsite before greeting the Bear River, marking the trail’s end a mere half mile south of the southern trailhead. Enjoy the last of the four permissible campsites on this leg of your journey, respecting the ban on fires to protect this pristine wilderness.
