Fourth Connecticut Lake Trail

The trail begins with a notably steep and rocky section along the U.S./Canada border, often referred to as the 'swath'. This part can be muddy throughout the year, though bog bridges are in place in the wettest areas. After about 0.6 miles of climbing, the path enters the woods and eventually descends to the lake. The forest around the lake is dense with balsam fir, red spruce, and birch, and the forest floor features various native plants. Sturdy hiking shoes are recommended due to potentially wet and slippery conditions.

This trail offers several unique features. It leads to the true source of the Connecticut River, Fourth Connecticut Lake, where the river begins as a small brook. A distinctive aspect is that the trail follows and sometimes crisscrosses the U.S./Canada border, allowing you to literally straddle two countries and two watersheds. The lake itself features a fascinating floating bog mat, home to insectivorous plants like pitcher plants and sundew.

The area is rich in wildlife, with opportunities to spot moose, beaver, spruce grouse, and northern three-toed woodpeckers. The forest around Fourth Connecticut Lake is characterized by balsam fir, red spruce, paper birch, and mountain ash. The forest floor is home to northern wood sorrel, creeping snowberry, bluebead lily, and goldthread, with wildflowers abundant at the southern end of the lake. The floating bog mat also hosts unique insectivorous plants.

The trail is generally accessible from late spring through fall. Wildflowers are abundant at the southern end of the lake during warmer months. Hikers should be prepared for potentially wet and muddy conditions throughout the year, especially in spring. Winter hiking is possible but requires appropriate gear and experience due to snow and ice.

Parking is available at the trailhead for the Fourth Connecticut Lake Trail. Specific details regarding the parking area can often be found on local forest service or park websites. It's advisable to check for any current advisories before your visit.

The Fourth Connecticut Lake Preserve is managed by The Nature Conservancy. While there are typically no entrance fees for day hiking, it's always a good idea to check the official Nature Conservancy website for the Connecticut Lakes Headwaters Natural Area (nature.org) for the most current information on permits, regulations, or any seasonal restrictions before your visit.

Generally, trails in preserves managed by The Nature Conservancy allow dogs, often on a leash. However, specific rules can vary. It's best to confirm the current pet policy directly with The Nature Conservancy for the Connecticut Lakes Headwaters Natural Area before bringing your dog.

The Fourth Connecticut Lake Trail is primarily an out-and-back trail, approximately 2.1 miles to the lake and back. However, there is a 0.5-mile loop around Fourth Connecticut Lake itself, allowing for a circular exploration of the lake area before returning on the main trail.

The primary point of interest is Fourth Connecticut Lake, which is the official source of the Connecticut River. Along the way, you'll also experience hiking directly on or alongside the U.S./Canada border, offering unique views of the Boundary Mountains. The lake's floating bog mat with its unique flora is another highlight.

Yes, the route also passes through sections of the 4th Connecticut Lake Trail, the Cohos Trail, and the 4th Connecticut Lake Hike. Smaller portions of the route also overlap with Lauz Altitude and Sophie's Lane.

Be prepared for the initial steep and rocky ascent along the border swath. This section can be quite muddy, so wearing sturdy, waterproof hiking shoes is highly recommended. While the overall hike is considered easy to moderate, the challenging start requires some effort. Keep an eye out for wildlife, especially moose and various bird species, as the area is quite pristine.
