Yes, it was me trying to dispell this October 15th drop dead date that everyone bandies around. As of October 16th every year (you can still spend 10/15 in the park), there is no more overnight camping in the park (until winter season with considerably more rules believe it or not). The road remains open, as with everything else, weather permitting. They can have a Class IV day in July, but those are more common in approaching fall.
The AT takes you 10 miles from Abol Bridge (outside park boundaries on the Golden Rd/logging road) into Katahdin Stream, where the real climb begins. Then it’s 5.2 to the summit, the sign. It is feasable, although unlikely and not a lot of fun, to do this as a 30 mile (RT) day hike if you can’t drive into Katahdin Stream. If you can still drive into K.S. then this could be a 20 miler, 10 in, 5 up and 5 down.
But both sections could be broken up into two day hikes. (1) Abol to Katahdin Stream, exit park to Millinocket or wherever, spend the night and (2) back into Katahdin Stream and climb Katahdin.
What changed is that they used to bend the rules for thru-hikers and allow them to camp in the park after 10/15. I don’t know this for a fact, but as mentioned above, most likely there were problems and they discontinued that practice.
Hope this helps.
