The Mount Tom State Reservation has several parking areas. For a loop incorporating the T. Bagg, NET/M-M, and Keystone Trails, you would typically start from a parking area along Reservation Road. The T. Bagg Trail, for instance, starts directly from Reservation Road, providing an entry point to the interconnected trail system.
This loop is rated as difficult. It combines sections of the T. Bagg Trail (intermediate), the New England National Scenic Trail (NET)/Metacomet-Monadnock Trail (M-M) which is moderate to strenuous with significant elevation changes and rugged terrain, and the easier Keystone Trail. Hikers should be prepared for steep climbs, rocky sections, and considerable elevation gains and losses.
No, the "T. Bagg, NET/MM and Keystone Trail Loop" is not a single officially named or marked trail. Instead, it's a combined hiking experience that utilizes interconnected trails within the Mount Tom State Reservation. These trails, including the T. Bagg Trail, sections of the NET/M-M Trail, and the Keystone Trail, are well-documented and allow hikers to create their own loops.
You can expect diverse terrain. The T. Bagg Trail ascends over a rocky spine. The NET/M-M Trail section rides the skyline along steep west-facing basalt cliffs, offering rugged paths and significant elevation changes. The Keystone Trail, in contrast, features short climbs over loose rock and winds through wooded areas. During winter, sections of the NET/M-M can become icy and muddy.
This route offers several notable points of interest. You'll pass by Bray Lake, the Stone Crusher remains, and the Goat Peak observation tower, which provides panoramic views of the Connecticut River Valley. Along the NET, you can also find Dry Knoll with views of the Oxbow, and the ruins of the Eyrie House, a 19th-century mountaintop hotel, accessible via a short side hike.
Spring and fall are generally excellent for hiking this loop, offering pleasant temperatures and vibrant foliage. Mid-September is particularly special for hawk migration viewing at Mount Tom State Reservation. Winter hiking is possible but requires appropriate gear like ice spikes due to potentially icy and muddy conditions on the NET/M-M sections.
Yes, dogs are generally allowed on trails within the Mount Tom State Reservation. However, they must be kept on a leash at all times. Please remember to clean up after your pet to help keep the trails enjoyable for everyone.
As of current information, there are no specific permits required for hiking these trails. However, the Mount Tom State Reservation, where this loop is located, may have parking fees or other regulations. It's always best to check the official Massachusetts DCR website (mass.gov) for the most up-to-date information on park fees and regulations before your visit.
Yes, there is a spring-fed water fountain located at the historic CCC-built Visitor Center within the Mount Tom State Reservation, which is accessible from the NET. However, it's always recommended to carry sufficient water for your entire hike, especially on a difficult route like this.
For this difficult hike, sturdy hiking boots with good ankle support are essential. Bring plenty of water, snacks, a map, and navigation tools. If hiking during winter months, ice spikes are highly recommended for sections of the NET/M-M Trail due to potential ice and mud. Layered clothing is advisable year-round due to elevation changes and exposure.
Yes, this route extensively uses sections of other well-known paths. Approximately 46% of the route follows the Metacomet - Monadnock Trail and the New England National Scenic Trail. Additionally, about 29% is on the NET/M&M Trail (white), 28% on the T. Bagg Trail, and 23% on the Kay Bee Trail.
