About Giant Falls
Giant Falls is a scenic waterfall tucked inside Mount Rainier National Park and managed by the National Park Service. The cascade sits amid the park’s forested slopes and alpine backdrop that surround Mount Rainier, the stratovolcano protected by the park; viewpoints near the creek reveal the falls’ energetic flow framed by towering trees and mossy rock. Access to Giant Falls is a classic Mount Rainier day hike — a moderately rated out-and-back that rewards effort with a relatively secluded waterfall setting. The route covers roughly 4.0 miles with about 800 feet of elevation gain; trails and the surrounding landscape are managed by the NPS, so plan visits with park conditions and regulations in mind.
The Setting
Giant Falls sits at 4,531 feet within Mount Rainier National Park, fed by the Puyallup 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.
