Cascade Falls - 6.8 Miles Round-Trip

Cascade Falls is located 3.4 miles from North Inlet Trailhead on the west side of Rocky Mountain National Park. This voluminous, multi-tier fall pours over large granite boulders along a wide section of North Inlet Creek.

While Cascade Falls is the main attraction, the creek itself and large meadows along its path are equally compelling. Fishing is notably good on the North Inlet, and moose and elk sightings are fairly common.

The North Inlet Trail continues east with access to Lake Nokoni, Lake Nanita and Flattop Mountain on the Continental Divide.

While these destinations are typically tackled as an overnight, there are several features along North Inlet that can be reached comfortably in a day for those with more time to explore.

The Big Pool (9,080') is located 1.4 miles past Cascade Falls, a point where the powerful North Inlet is funneled through a narrow chute and slows into a large swirling pool. Ptarmigan Creek (9,345') is 3.25 miles from the falls, a major tributary of the North Inlet that can be traced via social trails and some moderate bushwhacking to Wardance Falls and its source at Bench Lake (10,120'):

The trail begins on a level dirt road across private property to the edge of Summerland Park (1.2 miles : 8,530’). It narrows onto single track and arcs NE around large meadows partially veiled by thin bands of timber - ideal habitat for seeing wildlife.

The trail undulates mildly into a lodgepole forest badly marred by pine beetles, though the herbaceous layer and creek corridor remain healthy and verdant.

It rises nominally to Twinberry Backcountry Campsite (2.93 miles : 8,740’), then high along the north valley wall before leveling back to the creek and a spur for Cascade Falls (3.4 miles : 8,845’).

Social trails branch down to viewing areas of the voluminous cascade; exercise caution when scrambling about this oft-slick area. Continue a few hundred yards past the falls into a large, luxuriant meadow fed by three major tributaries. This is an ideal place to find wildlife and solitude.

"We went up yesterday, I came from Los Angeles the day before, I am 63, hiked with 80 y.o. Father. Beautiful day, started at the main trailhead, overflow parking, so 3.5 miles each way, another mile or so if starting from lowe, on Grand Lake. We did the round trip in 3:10, plus 10 min at waterfalls, and I stopped too often to stretch back, or sit for 2 min...that is included in hiking time...families with kids 5-8 y.o. were passing us. The sign for NO DOGS was very hard to see, so several groups were turned around early because they started with a dog. Spectacular, easy hike."

"My boyfriend and I loved this hike! While the hardest part for us was making sure to keep slow so our bodies could handle the elevation (we come from St. Paul were the elevation is 702ft), the scenery is gorgeous! The first part of the hike has relatively minimal elevation gain, winding through an open meadow and into the forest. Once in the forest, the hike gains most of the elevation climbing to the falls! And Cascade Falls are amazing! We brought some snacks and enjoyed a break sitting near the falls. I would recommend this hike to all! Be sure to listen to your body if you are out of state and not used to the elevation change. And the trail is busier than a few other hikes we completed, so be sure to arrive early to find parking in the lot."
