Astronomy Program

Join NPS Park Rangers and an expert volunteer for a free stellar viewing of stars, planets, and galaxies! More information can be found here.

Bask in the night sky and all its wonders, questions, and curiosities at the heart of a historic vineyard. Observe the stars through telescopes and enjoy conversations with rangers.

Please bring warm clothing, blankets or chairs, water or warm drinks, and a flashlight (with a red light if possible).

Visitors should meet at John Muir NHS parking lot. We will guide you to the vineyard. Additional parking is available across the street on Walnut Ave. If it rains heavily, the program will be canceled.
