About Sunday Falls

Tucked into the towering evergreens of Mount Baker National Forest and managed by the U.S. Forest Service, Sunday Falls is a quiet, forested cascade that rewards hikers looking for a peaceful dose of Pacific Northwest scenery. The waterfall is most commonly reached via the USFS Glacier Basin Trail (Trail #719), and the approach threads through native-forest singletrack and mossy understory—an inviting spot for those who prefer less-crowded routes and a close-up of temperate-forest habitat. The hike to Sunday Falls is considered moderate: the full out-and-back route measures about 2.4 miles with roughly 350 feet of elevation gain. The USFS lists Glacier Basin Trail #719 (GIS length 0.48 miles on its maps) and records the trail as Class 3 with a natural (NAT) surface and typical grades between 12–20%, so you should expect some short, steeper pitches and uneven footing as you approach the falls. Bring good footwear and a steady pace to fully enjoy the tranquil setting managed by the USFS.

The Setting

Sunday Falls sits at 3,005 feet within Mt. Baker National Forest, fed by the South Fork Sultan River, in the mountains of Washington.

How we calculate this

This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.
