Sulphide Creek Falls is a waterfall in Whatcom County, Washington. It lies in or next to North Cascades National Park, so park hours, fees and rules apply. It sits roughly 45 km (28 mi) ESE of Peaceful Valley.
Sulphide Creek Falls is a tall, moderately large volume waterfall within North Cascades National Park in Washington state that is one of the tallest waterfalls in North America. The falls drop from Sulphide Lake (elevation 3,800 ft (1,200 m)) on the southeast side of Mount Shuksan down a narrow flume-like canyon to a broad basin below. Because of the narrow, twisting shape of the canyon the waterfall is exceptionally difficult to see from ground-level perspectives. The total vertical drop of the waterfall is in the range of 2,100 feet (640 m) to 2,200 feet (670 m) feet, but it has not yet been accurately measured. Foot access to the bottom of the waterfall involves 2.5 miles (4.0 km) of off-trail travel in extremely brushy terrain and several potentially dangerous fords of a large stream.From the Wikipedia article “Sulphide Creek Falls”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Waterfalls photograph best in soft, even light: overcast days, deep shade, or the hour after sunrise before direct sun hits the water. Bright sun on white water blows highlights and adds harsh contrast.

Milky Way & night sky
From Sulphide Creek Falls, the Milky Way core is visible in a dark sky from May through July. June gives the longest window (about 2.7 hours on a moonless night), and the core peaks around 12° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.72 mag/arcsec². Aurora needs roughly Kp 4.0+ 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 42% average cloud cover) and November as the cloudiest (76%). 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 waterfall
- Keep a microfiber cloth handy — spray drifts onto the lens, especially at the plunge pool.
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- A 3-stop ND filter lets you use slow shutter speeds even when the light is bright.
- Shoot a vertical and a horizontal frame; tall falls often work better in portrait orientation.
- Scout in daylight if you plan to shoot at night or before sunrise.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. 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.
