Summer Celestial Calendar


The Haliburton Highlands’ unspoiled darkness creates a perfect setting for both dedicated astronomers and casual stargazers. Within this peaceful landscape, the stars shine brilliantly, offering a deep sense of connection to the vast universe.

Whether you’re seeking profound cosmic insights or simply enjoying the breathtaking celestial display, this dark sky area offers an unforgettable experience under the night sky.

Did you know that the best time to observe stars and celestial objects is during a New Moon? At this time, the moon is situated between the Earth and the Sun, eliminating its bright light from the night sky and providing ideal stargazing conditions.
