If the goal is Zealand, then the easiest way to approach it is from the Zealand Hut side. You can get their via either N. or S. Twin, but those peaks have much steeper/rougher sections than the portion of trail passing thru the beautiful birch forest. Also - if approaching Zealand from the Twins - that section of trail just after turning left near Guyot - is very rough for about 1/3 mile. It's flat more or less, but a jumble of small boulders to navigate - not that big a deal but am always glad to get thru it. So if doing it from the Twins remember you'll have to navigate it twice.
Also - from Zeacliff over to Zealand is 1.6 as Ivy said. There are at least 3 puds along the way, so it seems longer (at least to me). There are 3 steep bits, and one of them has a ladder. They're quickly passed, and if you have any qualms, slide on your butt when descending. Not hard on the knees, though. Not as tough as they look, either.
