The Niagara Glen is probably the most popular spot on the list so far, well-known to locals as a great nature spot and a great picnic area. The Glen today has been mapped and identified by three different sections: Wintergreen Flats are the uppermost area, Wilson Terrace is the middle section, and Foster Flats are the lowest area. This area is away from the big gift shop and other attractions at the entrance to Niagara Glen.

Getting down to Foster Flats is very easy. After parking in the main car park along the Niagara Parkway, you can walk to the stairs that can be seen in the above picture. At the top of these stairs is the trail map pictured. Each of these paths is great in any season, and they are all marked with coloured trail markers the entire way. It's a perfect area for day hikes and afternoon adventures in virtually any season

Fosters Flats and the Niagara Glen have some very interesting geological history. Niagara Glen was actually the location of the Niagara Falls around 6,000 years ago. The waters of Lake Iroquois (Lake Ontario nowadays) were approximately 42 meters higher than the present day. When the water flow of the inland lakes increased, it caused the old falls to erode the south of the valley and drop the water level to what we see nowadays. This is also the cause for some of the massive boulders that can be found scattered around Foster's Flats. Originally these boulders were at the top of the Wintergreen Flats waterfall, but they came tumbling down as the erosion occurred.
