Grassholme Observatory sighting

Private Hire – Stargazing Events

A haven for stargazers and explorers.

The Grassholme Observatory is a purpose-built visitor attraction in Teesdale.

It is home to an array of sophisticated telescopes and instruments installed to help you explore the night sky and the universe around us. Situated on the banks of the Grassholme Reservoir in County Durham, it occupies a truly iconic location with stunning scenery and big dark skies free from any light pollution.

Our facilities have a 20-seater heated classroom and a purpose-built observatory housing an array of powerful telescopes, which allow visitors and budding astronomers to see deep into the night sky. Grassholme Observatory is an International Dark Sky Reserve, and we are committed to ensuring the nocturnal environment is safeguarded and protected for scientific, educational and public enjoyment.

Our humble beginning

Our founder Gary Fildes, who ran Kielder Observatory for over 17-year’s has an enthusiasm for all things involving the night sky, planets, and galaxies beyond our solar system. This passion for astronomy is something we all share here at Grassholme. We see the night sky as a magical experience we want to share with everyone who visits us.

Since Grassholme first opened, a lot has changed! We have high-tech state-of-the-art equipment that novice astronomers to passionate stargazers can use when visiting. Our equipment investment allows our visitors to see the wonders the universe has to offer. Each of our sessions and events is led by top astronomers, meaning you get the best people in the industry when you come to Grassholme!

At Grassholme Observatory, we strive to run a centre that caters to all our guests and their interests. We run introductory sessions and stargazing events for families and schools to educate people on the subject of astronomy. Whatever your astronomical preferences, we aim to satisfy them – take a look at our events page for more information. Our private observatory hire is the perfect birthday surprise or corporate night out under the stars. Whatever the celebration, the Grassholme Observatory is ready and waiting for your group.

Demand for events is high, so please book early to ensure your private observatory event is reserved. For more information, contact us or get in touch with us on social media.
