Operating Hours & Seasons
In general, the Appalachian Trail is open year-round. The northern terminus at Mount Katahdin in Maine is within Baxter State Park, which may be closed in winter months, depending on weather conditions. Particular sections of the Trail, and less-developed roads accessing the Trail, may be closed temporarily for a number of reasons, but otherwise the trail is open.

The A.T. is marked with two inch by six inch vertical white paint blazes. A double blaze, one above the other, is placed before turns, junctions, or other areas that require hikers to be alert. There are approximately 165,000 blazes along the Appalachian Trail.
