The biggest benefit of visiting Rocky Mountain National Park in October is that the visitor numbers drop significantly from the previous months. In fact, they are less than half what they are in September—averaging around 300,000. A visit in October presents an opportunity to hike on trails that in the high season are incredibly crowded.

The biggest drawback of an October visit to Rocky Mountain National Park is potential road closures. Trail Ridge Road is typically closed beginning in mid-October starting at Many Parks Curve. Old Fall River Road closes in late September or early October. Depending on the weather and the date of your visit, it is important to keep this possibility in mind and plan accordingly. You can check the most current road conditions in the Park here.

Bicycling: Experience the wonders of Rocky Mountain National Park on two wheels! Biking options in Rocky Mountain National Park vary, so you can choose your own adventure. If you don’t have a bike, you can rent one in Estes Park.  Trail Ridge Road closes to vehicular traffic in mid-October, but it is open to bicycles until November 30th. Old Fall River Road may or may not be open so please check the current conditions. Trail Ridge Road gains over 4,000 feet in elevation over its 48 miles. Old Fall River Road is gravel, so you’ll need a mountain bike. Depending on your time constraints and fitness level, you’ll likely need a “shuttle”—another car to pick you up if you choose to bike either road only one way.

Hiking: Hitting the trails in October is one of the most highly recommended activities. The weather is pleasant and the foliage is phenomenal. In the next section, we highlight some of our favorite fall hikes in Rocky Mountain National Park.

Backpacking: If you’re looking for more than a day hike, Rocky Mountain National Park has plenty of spectacular routes for multi-day backpacking trips. The weather in October is ideal for backpacking but it is essential to pack warm layers for the chilly nights in higher elevations. Backpacking permits are required and can be purchased at the Wilderness Offices located at the Beaver Meadows Visitor Center or the Kawuneeche Visitor Center.

Take a Guided Tour: If you’re short on time for planning, let a guided tour show you the sights. Wildland Trekking has options for guided backpacking tours and guided day hikes through Rocky Mountain National Park.

Fishing: Trout fishing in the lakes and streams of Rocky Mountain National Park is the best in the fall months. Keep in mind that there are possession limits, catch and release regulations in some areas, and you need a Colorado fishing license for anyone 16 years of age and older. Before you head out read the full list of rules and regulations here.

October is beautiful for hiking the trails at Rocky Mountain National Park—lingering golden aspens color the landscape and the weather is quite cool. Below are a few suggested hikes for October:





1.  Twin Sisters Peak

  • Mileage: 7.0 miles round trip
  • Elevation Gain: 2475 feet
  • Trailhead: Lily Lake

The first three miles are a moderate climb, followed by switchbacks, and then another moderate climb through beautiful golden aspen and evergreens. At mile 3 you will exit the forest. The next half mile takes you through a rocky field and the views become ever-expansive and breathtaking. When you reach the saddle you’ll be standing in between the two peaks. Feel free to ascend either peak, or both. Each is only another 100 feet of elevation gain.

2. Sky Pond

  • Mileage: 9.0 miles round trip
  • Elevation Gain: 1780 feet
  • Trailhead: Glacier Gorge

Begin your hike at the Glacier Gorge trailhead in the Bear Lake area. Your first destination is the 30-foot plunging Alberta Falls, located within the first mile of this hike. Within the next mile, you’ll reach two trail junctions, North Longs Peak Trail (turn right) and Mills Junction (continue straight). Next, you’ll climb up switchbacks through a beautiful gorge till you reach the subalpine lake Loch Vale at 2.8 miles. At the foot of the lake, you’ll have spectacular views of Taylor Peak. After leaving Loch Vale, you’ll climb again for another 0.8 miles and take the trail junction to the left to continue on to Sky Pond. Climb the next half mile to reach the base of Timberline Falls. The next section of the trail runs along Timberline Falls where you’ll have to rock scramble up 100 feet. If you so choose, Glass Lake will be your reward. A rocky trail around the west side of the lake takes you 0.4 miles to Sky Pond at 10,900 feet with sheer cliffs of granite towering above you. It will be worth the effort to see this magnificent sight.

3. Cascade Falls 

  • Mileage: 6.8 miles round trip
  • Elevation Gain: 430 feet
  • Trailhead: North Inlet

Hiking in the Kawuneeche Valley in the fall is quite special. In the fall, there is plenty of brook trout in North Inlet Creek, so you can bring along your fishing rod. This hike runs along the North Inlet trail, which is part of the larger Continental Divide National Scenic Trail. Though this hike is almost seven miles, it has an easy elevation profile. It takes you through an open meadow with golden quaking aspens, lodgepole pines, and the occasional marmot.  An evergreen forest grows ever thicker up to the three-mile mark. Take the junction to the right to reach the 40-foot Cascade Falls which can be viewed from above or below. Be careful with the rock scramble up to the top if you choose to do so. A large meadow is just beyond the falls, a good place for a picnic lunch, but beware of wildlife as moose and elk are often spotted here.
