Katahdin is closed for winter — and with it the A.T. finish
As of 13 October, Baxter State Park in Maine has closed all trails on Katahdin and on Traveler Ridge for the season. The park says it does so to protect alpine ecosystems and the trails themselves. The date each year depends on the weather.
The Chimney Pond Trail to Chimney Pond Campground stayed open for campers only until 15 October. Katahdin Stream, Daicey Pond and Kidney Pond campgrounds close on 22 October. From 15 October the park again takes applications for winter camping and hiking.
Among the closed routes is the Hunt Trail — the Appalachian Trail’s climb to the summit. The Appalachian Trail Conservancy had already written in September that the A.T. up Katahdin would close with the arrival of snow, and that this year’s date was 13 October. The park each year has urged thru-hikers to summit by 15 October.

Context
Baxter Peak on Katahdin is the northern terminus of the Appalachian Trail: since Myron Avery fixed it there in 1933, about 2,190 miles of trail run up from Georgia to this summit. Most thru-hikers walk north and end their season here, usually in September.
So the autumn closure of Katahdin is not just “one mountain in a park.” While the Hunt Trail is shut, a classic northern finish is impossible until spring: anyone who missed it has either already flipped and walks south, or waits for next season. The rest of the A.T. in Maine and farther south stays hikeable; what closes is the finish summit. Winter in Baxter is a separate permit regime, not the ordinary thru-hike finish.
