The Mahoosuc Notch area is commonly known as the "hardest mile on the AT". The Appalachian Trail traverses many miles, many mountains, and many states, but this rocky section of the trail in Maine has been crowned the most difficult. The Mahoosuc Arm section stretches another mile or so up to that high point and includes a pretty rough section of trail, itself. Don't expect to move very quick for this stint of the Appalachian Trail!

The trail moving through Step Falls Preserve follows Wight Brook the entire time, which is lined with different cascades and small waterfalls, falls just outside the boundaries of Grafton Notch State Park. The trail is more primitive than the waterfall trails within the park, but it also offers more solitude.

Moose Cave in Grafton State Park is named after the moose that fell down into the cave years ago. The trail leading to the cave overlook winds through rock gardens and boulder fields before arriving at the halfway steps. This isn't a super smooth trail, but it's pretty short and offers a submersion into the forest of Grafton State Park.

The path to Mother Walker Falls is super short and super smooth. The waterfall is pretty popular since it's so easy to get to. The water, itself, is a collection of rapids and cascades along the Bear River and is one of the main attractions in Grafton Notch State Park.
