The Boulder Loop Trail is located within the White Mountain National Forest. While there isn't a specific permit for this trail, a recreation pass may be required for parking at some trailheads within the National Forest. It's advisable to check the latest regulations on the White Mountain National Forest website or at local ranger stations before your visit.
The terrain is diverse and moderately challenging. It starts with a gradual incline, becoming steeper as it winds through ledges and boulder fields. You'll encounter rocky sections with roots, short switchbacks, and some stone steps, especially on the descent. Supportive footwear is recommended due to the varied surfaces.
This trail is notable for its numerous massive glacial erratics, or boulders, which give it its name and create a unique landscape. It also offers spectacular panoramic views of the Swift River Valley and surrounding mountains like Mount Chocorua and Mount Passaconaway from several ledge viewpoints. The loop format ensures constantly changing scenery, and it's accessed after crossing the historic Albany Covered Bridge.
The trail offers scenic views throughout the year. Spring and fall provide pleasant temperatures and vibrant foliage, making them ideal. Summer is also popular, but be prepared for warmer weather. Winter jogging is possible, but conditions can be challenging with snow and ice, requiring appropriate gear.
Yes, the trail is generally dog-friendly. However, as it's located within the White Mountain National Forest, dogs must be kept on a leash at all times to protect wildlife and ensure the safety of other trail users. Please remember to pack out all waste.
Absolutely! The trail features several ledge viewpoints offering panoramic vistas of the Swift River Valley and prominent peaks like Mount Chocorua and Mount Passaconaway. You'll also encounter impressive glacial erratics, which are giant boulders scattered along the path, some showing drill marks from quarrying. The trail itself, known as the Boulder Loop Trail, is a highlight in itself.
While rated moderate, the trail has sections with significant elevation gain and rocky terrain, which might be challenging for absolute beginner runners. However, its unique boulders and potential for 'caves' make it a fun and engaging experience for families and children who enjoy exploring rocks. It's a good workout with excellent views for the effort.
Yes, the route primarily follows the Boulder Loop Trail for its entirety. There is also a very small section that intersects with West M N F Road.
Given the varied and often rocky terrain, supportive footwear such as trail running shoes or light hiking boots is highly recommended. Dress in layers suitable for the weather, and bring water, especially on warmer days. A map or GPS device is also useful, though the loop is generally well-marked.
Some sources suggest going left onto the west fork (often referred to as the 'blue route') for the ascent, as it climbs alongside an enormous cliff with short switchbacks. The descent on the other side (the 'orange route' or Boulder route) often includes a series of stone steps. This can offer a more challenging climb and a gentler, though still rocky, descent.
