Woops! Yeah, route 16.
Anyway, my wife and I did a SOBO section through the Whites together (I was going NOBO on the AT, but flipped through the whites because of logistics). Anyway, here was our itinerary. We had planned 100 miles in 7.5 days, seems reasonable, right? We did 90, and it kicked our butts, and we hike/climb all the time.
Day 1, a half day: US 2 to Imp campsite, 8 miles. Nice little spot.
Day 2, Imp campsite to Pinkham notch, 13.1 miles, walked to visitor center, Joe Dodge was booked, walked 1/4 mile back north on AT, "stealth camped" about a hundred yards off trail, many sites, many other tents. The guy in the visitor center/store/restaurant (whatever you call it) told us about these sites.
Day 3, Pinkham to Perch shelter/camp, about 10 miles, pain in the butt because the Perch is a full mile off the trail and a bit of a drop, but nice camp spot, platforms, scenic, worth the side trip off trail. The hike up from the Osgood campsite to Mt. Madison is what I consider to be the toughest couple of miles on the entire AT. We had a nice break at the Madison hut.
Day 4, Perch camp to Mizpah hut, 10 miles, basically a tough but beautiful day along the high ridges and of course Mt. Washington. We stopped for a nice break at Lake of the Clouds. We had pre-booked the hut, expensive but worth it, as has been said, we were on vacation! If you join the AMC, the huts are cheaper, I forget the discount, but if you stay in 2 or more huts, the membership pays for itself, plus you get other discounts.
Day 5, Mizpah to Zealand Falls hut, 14.1 miles, there is actually a very easy 5 mile stretch along this section. We had planned on finding a stealth camp, but had such a fine stay at Mizpah, decided to stay at Zealand Falls hut, what turned out to be our favorite hut
Day 6, Zealand to Garfield Ridge campsite/shelter, 9.7 miles, can't remember much about this day, but it was clear we weren't going to make out 100 miles to Glancliff in our 7 nights/7.5 day time frame, but making it to Kinsman notch would work (90 miles).
Day 7, Zealand to Lonesome Lake hut, 10.3 miles, another fine hut, we practically owned it (one other party of two was staying).
Day 8, 13.4 miles to Kinsman notch where we had arranged a shuttle to Glencliff and our car.
So, 7.5 days we made it 90 miles for a 12.5 MPD average, and we can normally hike 18-20 MPD easily. Tough terrain! But gorgeous.
One thing to remember if you do choose to stay in a hut or two: you can bring much less food along. We hiked 7.5 days but only started with 4-4.5 days of food. You can replenish a few snacks at the huts, as well as eat dinner/breakfast if you're staying, of course.
So again, 3 huts, 1 shelter and 3 campsites, all of which were legal, except maybe that one across route 16 from Joe Dodge Lodge, where at least a dozen others were camping and there were many established sites? I honestly don't know that thuis was strictly legal or not, I'm sure the WB police will tell me if it wasn't.
