Flat: into Zealand Notch from the Zealand Trail, then across on the Ethan Pond Trail to Thoreau Falls. In the notch, you end up in an open area at the foot of Whitewall with great views.
Climbing: into Zealand Notch from the Zealand Trail then up the Twinway past the hut to the Zeacliff lookout. From the cliffs you have the full panorama of Zealand Notch all the way to Carrigain and the Bonds.
Easy climbing: the Welch-Dickey loop never fails to impress with extensive open ledges with wide views. The foliage was already turning to some magnificent reds and yellows this past weekend.
So many more possibilities, but those pop into my mind first.
One note: Zealand Notch has a lot of birches, and tends to be golden. The area around Welch-Dickey has a lot of maples and there were many bright reds. You may want to take foliage species into consideration.
