John Muir National Historic Site
Astronomy Program
Join Rangers for the first Astronomy Program of the year! Please arrive at the John Muir National Historic Site parking lot at 4202 Alhambra Ave., Martinez, where staff will guide you to the historic vineyard.
Enjoy an evening of stargazing, telescope viewing, and a Ranger‑led conversation beneath the night sky. Feel free to bring blankets or chairs, water, and a flashlight—red light preferred to protect night vision.
