22 miles, Full day
The Presidential Traverse is an excellent and well traveled hike of some of New England's highest peaks - almost all at maximum exposure. At roughly 22 miles & nearly 9,000' of elevation gain this trip is not for the faint of heart or mind to be attempted in just one day - but it can be done with the right preparation. An official Presidential Traverse begins at Madison to Adams to Jefferson to Washington and then on to Monroe to Eisenhower to Pierce & finally Jackson.
My recommendation is to plant one car on 302 at the end of the Webster-Jackson trail and then drive a 2nd car to the beginning of the traverse off route 2(Presidential Highway) in Randolph NH at the Appalchia Trailhead.

What to bring? Here are the must haves!
AMC White Mountain Trail Map - Presidential Range
I recommend a 3L Camelbak & (2) 32oz Nalgene bottles filled with Gatorade or Smart Water for electrolytes
4 packages of Clif Shot Bloks
4 Clif Gel Shots
in addition to whatever foods you pack
Gotta bring a 1st aid kit
I mean - all these things are pretty basic for hiking but don't go w/o adequate food/water/first aid & orienteering supplies.
