Killarney Provincial Park, Provincial park in Sudbury District, Canada

Killarney Provincial Park is a wilderness provincial park about 90 km southwest of Sudbury, straddling the La Cloche range of large rounded white quartzite hills on the north shore of Georgian Bay. Its white peaks and cliffs contrast with pine and hardwood forest and boggy lowlands around many lakes. The photograph shows a low rocky point of tan and grey slabs topped by tall conifers, with small snow patches, projecting into the water.

The Ontario government designated the area as a park in 1964 after artists and conservationists had campaigned for its protection for years. The designation preserved a landscape that had appeared in Canadian paintings since the 1920s.

The park's existence stems from artists: A.Y. Jackson of the Group of Seven petitioned the province to save Trout Lake from logging, and it was renamed O.S.A. Lake after the Ontario Society of Artists took it into trust. Franklin Carmichael, Arthur Lismer and A.J. Casson also painted here, and a lake was named for Jackson on his 90th birthday.

George Lake Campground offers access to beaches and walking routes near the main entrance. Year-round yurts provide shelter for visitors who prefer not to pitch tents.

An astronomical observatory from 2010 makes this the first park in Ontario with public stargazing facilities. Visitors can join evening programs that take advantage of the dark skies over the La Cloche Mountains.
