Katahdin, Dudley - Knife Edge - Saddle is a 4 mile loop trail located near Millinocket, ME and is rated as difficult. The trail is primarily used for hiking and is accessible from June until August.
Stellar Views, rigorous workout You should plan on at least 2 hours to climb this 1.2 stretch of the Dudley trail. It is pretty steep and very rough, as is all of Katahdin. There are only 3 ways off of Pamola - the knife edge, Heelon Taylor to roaring brook or back down the Dudley trail. The Knife edge is very rugged in places - the chimney is almost a technical climb. The Baxter peak side of the knife edge is a boulder scramble. The saddle trail has a 1/2 mile section of scree and is also very steep. A tough hike that you should be in shape for. The most difficult and time consuming portions of the hike are exposed and above tree line.
This is the best hike in Maine. Also the best route from Chimney Pond in my opinion. The Knife Edge is narrow, but fear not, walk with confidence and it's easily passible. I was there on Sept 1, 2012 and the weather was perfect. I can't wait to book this year.
