AT A GLANCE
Why go?
Horseshoe Falls is a broad cascade braiding down the Roaring River in Rocky Mountain National Park, Colorado, spilling across a jumbled field of boulders known as the Alluvial Fan near Horseshoe Park. Unlike most of the park's waterfalls, it asks almost nothing of its visitors: a short, flat, fully accessible path leads from a parking lot to a viewpoint framed by aspens, with the jagged Mummy Range rising behind. The falls owe their horseshoe curve—and the entire wild, stony landscape—to a 1982 disaster.↗↗
It is one of the easiest and most reliably rewarding stops in the park, ideal for families, casual visitors and anyone wanting mountain waterfalls without a strenuous hike. Park rangers single out autumn, when the aspens in nearby Endovalley turn gold around the falls.↗↗
A landscape born from a flood
Before the area became part of Rocky Mountain National Park, a small earthen dam was built above Lawn Lake to raise its level. On an otherwise ordinary summer day in 1982, nearly 100 feet of that dam gave way, sending a wall of water reportedly some 30 feet high thundering down the Roaring River canyon. The surge scoured away forest, carried boulders—some weighing over 400 tons—and finally spread out into the wide, sorted field of gravel, sand and rock now called the 42-acre Alluvial Fan. The river, re-cutting its path through that debris, took the sweeping horseshoe bend that names the falls. The flood claimed three lives and reached all the way into downtown Estes Park before being stopped at Lake Estes.
