About Fan Falls
Fan Falls is a quiet, picturesque cascade tucked inside Rocky Mountain National Park and managed by the National Park Service. The falls are a lesser-known gem for visitors who want a peaceful mountain setting: expect the gentle rush of water framed by subalpine forest and open meadow vistas rather than a crowded overlook. Because it sits inside the park boundaries, fan-shaped cascades and surrounding ridgelines feel protected and pristine under NPS stewardship. The hike to reach the falls is approachable for most hikers with some experience: the trail is a 3.0-mile out-and-back with about 500 feet of elevation gain and is rated moderate. The route threads through forested sections and open meadows with occasional rocky approaches, making for varied scenery and good viewpoints for photos. The nearest developed camping is at Arapaho National Recreation Area, roughly 15.0 km away, so plan accordingly if you intend to camp before or after your visit.
The Setting
Fan Falls sits at 11,099 feet within Rocky Mountain National Park, in the high alpine of Colorado.

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.
