We only had two and a half days to spend in Acadia, and this was the trail we chose to finish our trip with. It was a great hike with beautiful views, but knowing a few things first would have made our experience better.
1) Don't worry about the ladders. Trust me when I say that the ladders are quite easy to navigate. The reason that the trail is referred to as a non-technical climbing route is most likely because of the rock fields that have to be navigated, in which there is no trail. In these rock fields you must follow painted blazes, but you can choose whatever route you feel like.
2) If you don't like heights, find a different trail. There are several times when the trail goes along ledges where there is very little separating you from a very long drop. I never felt in danger, and you should be fine as long as you're careful, but its good to know.
3) Bring water and stop at the restroom. There is no water available on the trail except what you bring with you, and you will definitely get thirsty if you're hiking in the summer. Likewise, there are no restrooms, so do your business before hand.
4) Look for blueberries! We were in Acadia in early-August and there were ample amounts of wild blueberries to be had if you looked for them. They won't fill you up much, but they make a nice snack.
5) Don't come down the Precipice Trail. It may seem convenient, but then you will have to navigate those ladders and ledges and rock fields while going downhill. Instead, follow the East Ridge Trail down...I think that's what its called.
6) Do not take the Orange & Black Path. This was our biggest mistake. We were coming down the ridge trail when we saw the turnoff for this trail. It looked like a shortcut on the map, but it isn't. It makes the hike much more strenuous and quite possibly longer.
Overall the hike really was a great experience. It was a challenging hike with absolutely stunning views, especially compared to the fog we had had the day before, and you can get free blueberries. It probably isn't a great hike for families with small children, and it would be quite difficult for someone who was out of shape. But if you're on the fence, I say go for it.
