Downtown to Orléans is a beautiful ride! I'm always a bit annoyed at the cars around Rockliffe Park, but the ride is much more bearable if you take the bike lane all the way until you're in the Ottawa River Pathway.

Soon after Rockliffe Park there's a bike path that's parallel to a gravel path, it's highly recommended to take the gravel even on road tires, the views by the river are gorgeous!

🐿️ Beware of little critters as you cruise through the woods. Bring a light after dusk!
