Northwest of Vancouver and northeast of Campbell River, the north end of Quadra Island has mile of old, decommissioned logging roads open to ATV riding. These roads are serviced by several trailheads, and the options seem endless. These old routes are vary challenging and a winch (and the experience of how to use one) is highly recommended.
To get started, head north on the island toward the Walcan Fish Plant, and then select a loging road in the area. The local gas stations on the island have trail maps.
Note: the locals may not be too friendly to ATV riders.
Note: As of August 2008, the Ministry of Forests Regulations require all ATV drivers to be at least 16 years of age and have a valid drivers license to ride on Forest Service Roads. In addition, the ATV must have valid third-party liability insurance, which is typically around $120 per year. The Conservation Officers will issue a $600 ticket if you do not have proof of insurance.
Overall, Quadra Island is the 33rd most popular ATV riding trail of all 61 ATV trails in British Columbia.
