Niagara Glen

Niagara Glen. The 82.5-acre Niagara Glen nature reserve has 4 km (2.5 miles) of hiking trails through forested paths that pass giant boulders left behind as the falls eroded the land away thousands of years ago. Some trails are steep and rough, and the Glen has an elevation change of more than 200 feet. Niagara Falls, ON. www.niagaraparks.com/nature-trails.
