Although Big Creek Park is located only 100 km south-west of Williams Lake as the crow flies, there is no road access to the park boundary. Two routes link to trails into the park. They follow logging roads, so watch for industrial traffic and use headlights. Roads become very slippery when wet: four-wheel drive, shovel and tire chains are recommended.
