About The Big Falls
The Big Falls is a scenic waterfall in Kentucky prized for its wooded setting and peaceful cascade. The approach rewards hikers with close-up views of the falls and a quiet atmosphere that makes it popular with weekend hikers and nature lovers. The site sits within the Fort Knox land unit — a military (MIL) property owned by DESG and managed by the U.S. Department of Defense — so plan ahead and confirm access before you go. The hike to the falls is a moderate out-and-back route of about 2.0 miles round-trip with roughly 300 feet of elevation gain. The trail threads through forested terrain with dirt and rocky tread that can get muddy or slippery after rain; it’s generally well-marked and offers pleasant viewpoints on your way to the waterfall, which is the highlight of the outing.
The Setting
The Big Falls sits at 499 feet within Fort Knox, fed by the Pond Creek, in the coastal lowlands of Kentucky.
Trail & Hike Details

Trail Description
Distance: 2.0 miles (out-and-back). Elevation gain: ~300 feet. Difficulty: moderate. The trail surface alternates between dirt and rocky sections and is well-marked for most of the route. Expect a steady, moderate grade as you climb toward the falls; the tread can become muddy and slippery after wet weather, so sturdy footwear with good traction is recommended.

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.

Weather Forecast
The Terrain, Seen by LiDAR
Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.
The bare-earth surface loses about 43 feet through the falls, but gradually, the profile of a cascade rather than a plunge. The ground at the falls is roughly 499 feet above sea level.
The ground changes about 45 feet in the 500 feet above the falls and 104 feet in the 500 feet below. The falls face southeast and catch soft morning light.
