Kepler Cascades

Overview

Kepler Cascades is a fast, rewarding stop: a multi‑tiered waterfall on the Firehole River dropping roughly 150 feet in total, with the tallest single step about 50 feet. It sits about 2–2.5 miles south of Old Faithful along the Old Faithful–West Thumb road, and you view it from a sturdy overlook above a narrow gorge.

What You'll See

From the boardwalk platform you look down into a tight canyon as the river stair‑steps over several ledges—loud, photogenic, and easy to appreciate in just a few minutes. The vantage is from above, and there’s no safe access to the base.

Getting There

It’s a simple roadside pullout with a very short walk to the viewing platform—perfect when you’re traveling between Old Faithful and West Thumb or heading toward Grand Teton. If you want to turn a quick stop into a mini‑adventure, the nearby area also serves as access for the Lone Star Geyser trail.

History & Geology

The cascades were noted by the 1870 Washburn–Langford–Doane expedition and officially named in 1881 by Superintendent Philetus Norris for Kepler Hoyt, the territorial governor’s son. The Firehole River has carved a gorge through trachyte lava here, creating the stepped profile you see from the overlook.

Best Time to Visit

Light is kinder in the morning or late in the day, which helps with shadows in the steep gorge. Mid‑day is the busiest window and the small lot can fill, so aim early or later for an easy pull‑in and better photos. Plan 5–10 minutes unless you’re lingering for shots.

Practicalities

There are no facilities at the pullout—no restrooms or food—so plan your stops accordingly. Stay behind the rails; drop‑offs are significant. Expect to do all your viewing from the platform.
