From the Willowbrae Trailhead, the Halfmoon Bay branch starts about 1.3 km into the route. The full walk is 1.8 km each way and rated moderate. Expect an 80 cm boardwalk section, muddy stretches, and long flights of stairs down to the beach. The stairs are the main commitment, so this is a poor fit if you can't comfortably manage them.
Willowbrae Road turns off Highway 4 about 2 km south of the Ucluelet–Tofino junction, then runs about 250 m over gravel to the trailhead. The trailhead isn't signed from the highway and park visitor parking is very limited. Nearby spaces serve Wya Point Resort, so don't count on them. The trailhead lot has a composting outhouse; no beach-side facilities are listed.
