The historic Arrowsmith CPR Regional Trail was built in 1912 by the Canadian Pacific Railway to service guests at its Cameron Lake Resort. The trail winds uphill from Highway 4 through private forest lands to the Alberni-Clayoquot Regional District's park, which was previously a ski hill.
It takes about four hours to get to the old ski hill, and about halfway up there is a fantastic view of the lush land below. The entire trail is about 10 km with an elevation gain of 1,000 meters.
Park at the Cameron Lake day-use area and cross the highway to access the trailhead.
