I just spent the last 4 days in Acadia National Park with several youth group students. Acadia is probably the most naturally beautiful area in all of New England. The park doesn't have the same "wow" factor as other parks like Yosemite or Yellowstone, but the combination of the mountains and the Atlantic Ocean make it a really unique place. I made the kids hike Cadillac Mountain. Reluctantly, we all made it to the top. I wish my kids liked hiking as much as I do.
