Lumpy's Epic is a 9-kilometre loop trail on the southern edge of Pemberton, BC, easily accessed from One Mile Lake.

Originally built as a dedicated mountain bike trail, it has become popular with hikers and trail runners seeking access to the top of Signal Hill Mountain.

The route climbs through forested terrain with a moderate elevation gain, passing several scenic viewpoints overlooking the Pemberton Valley and surrounding mountains. The trail is considered moderate and suitable for a range of skill levels.

It finishes along the eastern shore of One Mile Lake, where a lakeside beach offers a natural rest stop. Note that as of 2026, the One Mile Lake Boardwalk section is temporarily inaccessible.
