From the Globe and Mail:
Not far from one of Ontario’s most famous sights – Niagara Falls, attracting 14 million visitors a year – is one of the province’s best-kept secrets: a hidden playground of large rock formations spread throughout the wooded trails of the Niagara Glen Nature Reserve, just above the rapid, cool water of the Niagara River.
The Glen is known as a relaxing hideaway from the touristy crowds. What many people don’t know: It’s also the best outdoor bouldering spot Southern Ontario has to offer.
If you haven’t heard of bouldering, it’s like rock climbing but without a rope. You climb up four or five metres instead of 20. You need a lot of body strength to do it, but it also picks your brain.
