Get ready for a truly unique walk through history at the Othello Tunnels, carved right through the solid granite of the Coquihalla Canyon. The main trail is a flat and easy 3.5-kilometer round trip, making it a perfect adventure for everyone, just a short stroll from the parking lot. You'll be amazed by the sheer cliffs and the powerful Coquihalla River rushing below as you pass through the series of historic train tunnels and over trestle bridges.
