Logan Pass Star Party


Glacier National Park may or may not be offering Logan Pass Star Parties during 2022. Please check at a visitor center or ranger station for more information.

Join Park Rangers and members of the Big Sky Astronomy Club as they take advantage of Glacier's unusually dark skies, gazing through telescopes exploring the depths of the universe.

Admission by ticket only: Get yours from a bookstore at the Apgar or St. Mary Visitor Centers.

A donation of five dollars to Glacier National Park Conservancy will be gratefully accepted to fund future programs.

In case of inclement weather, programs will be held the following night. Check at visitor centers or park's social media accounts for information.

Nightly Astronomy Program


Half the park happens after dark! Glacier is a great place to observe the night sky and you can get the most out of that experience by joining our astronomers for one of our nightly astronomy programs. These programs are only offered during the summer and tickets and reservations are not required. Please see the Ranger-led Activity Schedule for specific days and times. However, programs are usually offered during July and August and begin at dusk and last until midnight.

Nightly astronomy programs take place in Apgar, on the west side of the park, and in St. Mary, on the east side. In St. Mary, astronomers use the park's Dusty Star Observatory at the St. Mary Visitor Center to help explore the cosmos. This observatory features a 20-inch telescope and astronomy camera to share views of the night sky with visitors watching on exterior television monitors. Traditional telescope viewing is available at both locations.

If you plan on attending an astronomy program it is important to come prepared. Wear warm clothing and come prepared for wind in St. Mary. Bring a headlamp or flashlight so you can safely move around in the dark. Seating is not provided at the Dusty Star Observatory so bring a chair for a more comfortable viewing experience.
