Hiking Trails in Ontario
Ontario is a beautiful place. The province is blessed with unique geological features, diverse wildlife, and an abundance of hiking trails for people of all experience levels to enjoy. We absolutely love hiking. It gives us an opportunity to disconnect from our electronic devices and experience all the beauty and wonders nature has to offer. Whether it is a stroll through a city park or hitting up parts of the Bruce Trail or hiking trails at one of Ontario’s many provincial parks and conservation areas, we love being outdoors. We are constantly looking for new places to visit and discover and sharing our experience with others in hopes of encouraging them to try hiking for themselves. We have compiled a list of hiking trails in Ontario using information obtained from Ontario Trails, All Trails, and other sources online. You can search for trails by name, by the nearest city, and by region. We are still working on making it sortable by trail length. We hope you find this useful. If there is a trail you think we should add, please leave a comment below and we will do our best to include it. Happy trails!
