My family and I hiked this trail on September 6th, 2005. By the end of it I learned that it's very important to pace yourself at the beginning of a hike, to avoid tiring out before reaching the top. The trail starts out with a gradual steepness, and there are really no places that are completely level. Towards the end there are a few portions that are very steep and mostly composed of rock, and those who don't pace themselves properly and/or aren't is a good shape as they thought they were will have to take several breaks ;-)
I don't recall many interesting sites along the way - there was a small stream at one point, of to the side of the trail. The view at the top is wonderful though. There's a great view of the ocean, which included many small boats tied up, at the time of year we were there. Most of the view is forestland - including Mount Battie, a smaller "mountain" nearby. There are a few buildings and roads visible as well.
