The ultimate backroad? The Alexander MacKenzie Heritage Trail is a top contender. Also known as the Nuxalk-Carrier Route, the Blackwater Trail, or simply the MacKenzie Trail. The trail is a 420 km long overland route between Quesnel and Bello Coola, British Columbia and is named after the explorer, you guessed it, Alexander Mackenzie. In the 18th century, MacKenzie embarked on his trek from Montreal to the Pacific Ocean. When he could not traverse via the Fraser River anymore, local First Nations guided him along what would become the overland MacKenzie Trail. He reached the Pacific Ocean on July 20, 1793. It was named an official heritage trail by the Heritage Conservation Act in 1987.
