Hiking in North Brother, Maine: trails, map and practical info

North Brother is a rugged mountain in Baxter State Park, located in Piscataquis County in the Maine Highlands. It sits within one of the most remote and wild corners of the northeastern United States, flanked to the northeast by Fort Mountain and to the southwest by South Brother — the two peaks together known as The Brothers. This is serious backcountry terrain, and the hike reflects that.

The Trail

The route to North Brother covers 15.4 km with 1,265 m of elevation gain, and most hikers should plan for around 6 hours and 15 minutes on the trail. It's rated moderate, though that rating deserves some context: the terrain in Baxter State Park is consistently demanding, and the remoteness of North Brother means you're committing to a full day in the wilderness with limited bailout options. Come prepared.

The mountain's drainage tells you a lot about its geography. The south and east slopes shed water into a low, swampy area known as The Klondike, which drains into Wassataquoik Stream, then into the East Branch of the Penobscot River, and eventually out to Penobscot Bay. The north and west sides drain into Little Nesowadnehunk Stream, Nesowadnehunk Stream, and the West Branch of the Penobscot River. That divide — right underfoot as you climb — is a reminder of just how deep into Maine's watershed you are.

The Setting

Baxter State Park is a place that operates on its own terms. There are no crowds, no cell service, and no shortcuts. North Brother sits roughly 8 km (5 miles) northwest of Mount Katahdin, the northern terminus of the Appalachian Trail — a 3,490 km National Scenic Trail stretching all the way to Georgia. Katahdin dominates the skyline from the upper reaches of North Brother, and on a clear day the views across the park are expansive and genuinely impressive.

The Klondike, visible from the upper trail, is one of the more striking features of this corner of the park — a broad, boggy wilderness basin that sees very little foot traffic and gives the landscape a raw, untouched feel. It's the kind of view that reminds you why people make the effort to get out here.

What to Expect on the Hike

The trail gains elevation steadily, with the upper sections becoming more exposed as you approach the summit. The footing can be rocky and uneven throughout, and wet conditions — common in the Maine Highlands — make traction a real consideration. Waterproof boots and trekking poles are worth bringing.

Wildlife is part of the experience in Baxter State Park. The area supports healthy populations of white-tailed deer, black bear, and moose, along with a wide range of bird species. Keep your eyes open, especially in the early morning hours.
