Everything You Need to Know about Hiking Mount Katahdin

Mount Katahdin is the tallest mountain in Maine, sitting at 5,269 feet located in Baxter State Park near Millinocket, Maine. It is also the Northern most point of the Appalachian Trail and is one of Maine’s most iconic sites.

Mount Katahdin is a severely underestimated mountain resulting in many injuries and even death. No matter what route you take to the summit, you are looking at 4,000 feet of elevation gain and a full day hike (most people spend between 8 to 12 hours on the mountain).

The park is open from 6:00 am to 10:00 pm. Unless you have a campsite reservation inside the park, you are unable to access trailheads until the gate opens at 6:00 am.

Camping in Baxter State Park

One of the easier ways to guarantee a chance to climb Mount Katahdin is by camping out in the park the night before. Most campgrounds are open from May 15 to October 15. Except for Chimney Pond which opens on June 1, Nesowadnehunk which opens on the Friday prior to Memorial Day, Loon-Dependent Wass Lake Island opens on August 15, and Cabin 12 at Chimeny Pond opens on August 1. Kidney, Daicey, and Katahdin Stream are open until October 22.

Personal Trail Recommendations for Mount Katahdin 

If you’re looking to hike Knife’s Edge, here is my personal recommendation for the best route to take to the summit. 

Start by parking at Roaring Brook Campground and hike Chimney Pond Trail or Helon Taylor. If you take the Chimeny Pond trail, once there, take Dudley to Pamola Peak. Once you reach Pamola peak you can access the summit by taking Knife’s edge. Once you summit, take Saddle Trail down until you reach Chimney Pond and take Chimeny Pond trail back to the parking lot!
