Chasm Falls Off Old Fall River Road In Rocky Mountain National Park

Chasm Falls On Old Fall River Road in Rocky Mountain National Park

With one jaw-dropping scenic overlook after another, Trail Ridge Road, the highest elevation continuous road in the United States, gets all the attention in Rocky Mountain National Park. But Trail Ridge Road wasn’t the first road through the national park. That distinction belongs to Old Fall River Road, which opened in 1920.

Fall River Road, an 11 mile, steep, narrow, one way, 15 mph, dirt/gravel road, was the first road in Rocky Mountain National Park offering access to the park’s high country and alpine tundra.

Along the drive from Horseshoe Park and the Alluvial Fan to the Alpine Visitor Center in Fall River Pass, Old Fall River Road passes a gorgeous waterfall that you can access from the bottom or the top.

Visiting Chasm Falls

Sitting at 9,068 feet elevation, Chasm Falls is a 25 foot plunging waterfall about 100 yards off Old Fall River Road in Rocky Mountain National Park.

As you travel up Old Fall River Road, the first access point for Chasm Falls is nothing more than a wide spot on a hairpin turn that fits maybe three vehicles. From this roadside pullout below the falls, a short and rough trail travels uphill over and around rocks and boulders to the edge of Fall River and a distant upstream view of the waterfall.

The view from the bottom is mostly of Fall River tumbling downhill over rocks. But the view from the scenic overlook a bit farther up Old Fall River Road offers the perfect view of the plunging, 25 foot, Rocky Mountain National Park waterfall.

At the top of Chasm Falls, there is a parking area alongside the road for about 10 vehicles. This is also the trailhead for a 0.1 mile, out and back trail to an observation platform. The trail travels downhill and down some natural stairs to the observation platform near the base of the waterfall.

It’s a short and beautiful walk for all ages and totally worth the stop.

From here you can:

  • See Fall River flowing toward Horseshoe Park downstream
  • See Chasm Falls upstream as it bursts through a granite chasm in Fall River, funneling its waters into a narrow gorge

On the trail, if you look closely at the waterfall’s gorge, you’ll find a hole-in-the-rock. It was created by water rushing under the rock and causing rocks to swirl in a whirlpool and carved and smoothed this hole. Uplift later tilted this rock on its side.

After seeing this beautiful waterfall and Adams Falls, we were excited to have time to check out Alberta Falls and Copeland Falls too! I just wish we had even more time to see the rest of Rocky Mountain National Park’s waterfalls!
