There are at least two waterfalls worth noting along Glen Brook Falls. Both are located on the property of the Berkshire School, which welcomes visitors. The lower falls are the most photo-friendly, with several tiers of draping plunges over polished rock, all set in a pretty ravine. A warning though: the lower falls can dry up, due to the presence of a small dam upstream.  The upper falls are about 0.25 mile upstream of the lower falls, and are viewable head-on once you reach a dam at the end of the access trail. These falls are obstructed by trees, so high water conditions combined with an early spring visit will be the best time to visit. The upper falls sit in a very peaceful area.
