The park was established in 1959, as Wilderness Provincial Park, to preserve the natural beauty and wilderness character of the area. In 1965, it was renamed after the Honourable Norman Willmore who, as Minister of Lands and Forests, did much to influence its establishment. Willmore offers spectacular mountain peaks, waterfalls, wildlife, diverse flora and fauna and a vast expanse of wilderness. Approximately 750 km of hiking trails provide access to all the major eastern valleys and form connections between valleys via high mountain passes.
Fewer trails exist in the western part of the park due to the more rugged terrain.
Jarvis Creek connects five lakes within the park. For water enthusiasts there is fishing, canoeing and water skiing. There are challenging trails for hikers and mountain bikers. Campgrounds offer a range of sites, from secluded and more rustic sites along Jarvis Creek to more modern sites at Gregg Lake. Visit the park office and borrow one of the family adventures packs, with five different packs of fun activities to enable you and your family to discover and explore the park's natural features.
