Tips for Stargazing in the Eastern Sierra

December 19, 2025

The dark night sky in the Eastern Sierra is what makes the region so spectacular for stargazing.

The Eastern Sierra, with its vast open spaces, high elevations, and minimal light pollution, is a stargazers paradise. This region offers some of the most unreal views of the night sky in California. Whether you're a seasoned astronomer or a first-time stargazer, here are some tips to make the best of your stargazing adventure in the Eastern Sierra.

When to Go Stargazing in Mammoth Lakes

While there is little light pollution in the Eastern Sierra, the darkest sky is when the moon is in its crescent or new moon phase. This reduces moonlight interference and allows for clearer views of the night sky. While a full moon is equally as spectacular in the Eastern Sierra, the bright light outshines even the brightest of the stars.

5 Top Tips for Stargazing in Mammoth Lakes

Check the Weather

The Eastern Sierra can experience rapid weather changes. Keep an eye on the forecast and be prepared for temperature drops, even in the summer. Clear skies are essential for stargazing, so plan accordingly. Find helpful tool kits to prepare you for your trip in our Summer and Fall Ready Guide as well as our Winter Ready Guide.

Pick the Right Spot

The best star viewing is in an area with no obstruction from buildings or trees. Even steep canyons or valleys limit the amount of night sky you will see. Find an open meadow, or a mountain pass for your stargazing destination. Minaret Vista is a local favorite for stargazing in Mammoth Lakes.

Avoid Light Pollution

When stargazing you are going to want to avoid artificial light. Whether you are camping or just stargazing, save the campfire for another night. The glow of the fire will diminish the brightness of the stars.

What to Wear and Bring

Nights in the Eastern Sierra, even in the summer, can be cold. Dress warmly and bring extra layers, including a warm jacket, beanie and gloves. A headlamp or flashlight is also helpful since you'll be seeking out darker areas to stargaze. Bring a chair for lounging or a blanket to throw on the ground. A sleeping bag is also a good addition for the colder nights.

Identify Stars and Constellations

Most of us can find the Milky Way and the Big Dipper, but if you want to identify the less familiar stars and constellations bring an astronomy guidebook or star chart along. Alternatively you can use your smartphone. With a number of free apps, understanding the night sky has never been easier or more accessible.
