Located in Mariposa County, California, Emerald Pool is a lake at about 1,543 m (5,062 ft) above sea level. It lies in or next to Yosemite National Park, so park hours, fees and rules apply. It sits roughly 3.5 km (2.2 mi) ESE of Yosemite Valley.

Golden hour & blue hour by month
Lakes reflect best in calm air — usually the first hour after sunrise, before breezes ripple the surface.

Milky Way & night sky
From Emerald Pool, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.3 hours on a moonless night), and the core peaks around 23° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.65 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 15% average cloud cover) and December as the cloudiest (54%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lake
- Expose for the brighter sky; reflections are typically half a stop to a stop darker.
- After sunset, long exposures smooth wind ripples into glass.
- For mirror reflections, get low and close to the water; the reflection grows with a lower camera.
- A polarizer can remove reflections to show the lakebed — or keep them, depending on rotation.
- Scout in daylight if you plan to shoot at night or before sunrise.
Season: Autumn mornings bring mist and fall color; high-elevation lakes are usually ice-free only from early summer to mid-autumn.
Suggested gear: Tripod, Circular polarizer, Wide-angle lens, Waterproof boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
