Experienced hiking enthusiasts will want to stop at the Niagara Glen Nature Centre. The facility will educate you on the flora, fauna and geology of the Niagara Glen Nature Reserve. Then, lace up your best shoes before selecting among the nine available trails ranging from moderate to difficult. You will weave along rugged paths through the Carolinian forest, inspect fossils in 400-million-year-old cliffs and marvel at the water rushing through the Niagara Whirlpool and Gorge. Guided tours are available during the tourist season.
