Where the Forest and Cosmos Meet

Step away from the city’s glow and into the ancient dark. Nestled in Calaveras Big Trees State Park, our Optical Astronomy Night series offers a stellar stargazing experience under the skies in the Sierra Nevada.

Our knowledgeable docent-volunteer astronomers set up powerful telescopes and guide you through the night sky — from the craters of the Moon to star clusters and deep-sky objects. Whether you’re a seasoned stargazer or picking up a telescope eyepiece for the very first time, this is a family-friendly program you won’t want to miss.

Bring a chair, a warm blanket, and your curiosity. We’ll show you the universe.
