In sticking with our "uniquely Acadia" theme, this hike offers great views of a glacially carved river valley that has wonderful cascades of water if it has been wet. Since the views are mostly tens of feet in front and around you, this hike is particularly good for overcast days and days when visibility is low.
Until you reach the intersection of the Trail and Giant Slide Road, it's just a flat walk in the woods. When you reach Giant Slide, the glacial remnants are all around you. In places, you are going under tunnels of glacial rock remnants. If it has been rainy, there are waterfalls and cascades everywhere. When you reach the first signpost, bear right. (If you go straight, there is a tunnel.) Follow along this trail until you reach a carriage road. Go left on the carriage road. When the carriage road crosses the Giant Slide Trail, take a left and return down the Giant Slide.
In a short distance, you've gotten a pretty good work out and a set of "Uniquely Acadia Views." On my "uniquely Acadia scale", I rate this hike a B+ to A-.
