Paradise Ice Caves is a cave in Pierce County, Washington. It lies in or next to Mount Rainier National Park, so park hours, fees and rules apply. The nearest town is Crocker, about 41 km (26 mi) away (Paradise Ice Caves lies SE of town).
The Paradise Ice Caves (also known as the Paradise Glacier Caves) were a system of interconnected glacier caves located within Mount Rainier's Paradise Glacier in the United States. These glacier caves were visited and documented at least as early as 1908. They have a varied natural history, as their size and even existence has changed over time, from a maximum surveyed length of 13.25 kilometers in 1978, to not existing at all during both the 1940s and 1990s due to glacial recession. In 1978 they were the longest mapped system of glacier caves in the world.From the Wikipedia article “Paradise Ice Caves”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Caves are lit artificially — show caves have fixed lighting, so a fast lens and high ISO beat flash, which flattens formations.

Local time (America/Los Angeles), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Paradise Ice Caves, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.3 hours on a moonless night), and the core peaks around 14° 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 ≈ 21.36 mag/arcsec². Aurora needs roughly Kp 5.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 29% average cloud cover) and January as the cloudiest (75%). August 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 cave
- Many show caves restrict tripods on tours; ask in advance or bring a small beanbag.
- Use manual focus with focus peaking in low light.
- Never touch formations — skin oils stop their growth.
- Follow White-nose Syndrome decontamination rules where posted to protect bats.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Cave interiors stay at a constant temperature year-round; summer tours fill up, so book ahead.
Suggested gear: Fast lens (f/1.8–f/2.8), High-ISO camera, Small beanbag. 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.
