The Killarney Provincial Park Observatory is an astronomical observatory located at the George Lake Campground of Killarney Provincial Park (a 420 km drive north of Toronto or a 100 km drive southwest of Sudbury).The Observatory is operated by Ontario Parks and houses two observatory buildings. The original facility contains a 10" telescope with solar filter, ideal for nighttime as well as daytime viewing of the Sun. The newer facility (built in 2018) contains a 16" fully automated telescope with a 5" refractor and is ideal for research, astrophotography and public use. Both telescopes are available for Discovery programs (formally known as Natural Heritage Education (NHE) programs) as well as private sign-out (self-use) by interested visitors.
