Wildfires create smoky chaos in Rock Mountain National Parkdrawbacks of visiting in august

One of the biggest drawbacks to an August visit is the potential for wildfires. The hot and dry conditions in the American West are the perfect breeding ground for wildfire activity by late summer. With that being said, August is still an extremely popular month to visit Rocky Mountain National Park due to summer vacation and good weather— if it isn’t smoky. Always check the most current conditions before you head out on the trail. If you choose to brave the crowds for a visit in August, here are some tips for navigating the busy Park:

Ride the shuttle bus: On the east side of the Park, there is a free shuttle bus that takes you to the many popular trailheads in this area. It’ll guarantee more time on the trails and less time trying to find a parking space at the busy trailheads.

Use the Grand Lake entrance: Over eighty percent of visitors enter Rocky Mountain National Park through the east side entrances (Estes Park, Beaver Meadows, Fall River, and Wild Basin). The west side of the Park is stunning— including lots of hiking trails and wildlife sightings.

Be an early bird: Get a head start on your day and watch the sunrise over the Continental Divide. Hitting the more popular trails before most people are even awake certainly has its perks.

Hike a less popular trail: with 355 trails in Rocky Mountain National Park, there are truly plenty of options for less crowded trails.

There is certainly no shortage of activities in August at Rocky Mountain National Park. From scenic drives to fishing or rock climbing, there is something for everyone in the summer. Below are a variety of options for things to do in August:





Take a Scenic Drive:

  • Old Fall River Road: Old Fall River Road (pictured left) is a gravel road that first opened in 1920, its purpose was to allow motorists up to the high country. Each year, it is open from July – October. It is a one-way, narrow 11-mile-long road with sharp curves that makes a steady climb. It also has no guard rails, thus the speed limit is 15 mph, for good reason! Old Fall River Road begins at Horseshoe Park, near the Fall River Entrance, where it climbs up steadily to Fall River Pass at 11,796 feet. It ends at the Alpine Visitor Center, where you can take Trail Ridge Road back to either Estes Park or Grand Lake.
  • Trail Ridge Road: Take a once-in-a-lifetime drive along the 48-mile “highway to the sky” — the highest continuous paved road in the nation. Travel up through montane meadows, subalpine forests, up to Milner Pass on the Continental Divide, and finally above the treeline. At its highest point, Trail Ridge Road reaches above 12,000 feet to breathtaking alpine vistas. Make sure to pack the right gear as it can be windy at the top and twenty to thirty degrees colder!

Rocky Mountain Half Marathon & 5K: This race is held annually and is widely considered one of the most scenic races in the country. You can get more information here.

Ranger Activities: Sign up for a bird-watching program, wildflower hike, guided tour along Trail Ridge Road, and interactive ranger-led wildlife talks at any of the Park’s visitor centers. Check out the programs here.

Stay at Shadowcliff Mountain: Finding economical lodging during the peak season is incredibly difficult. Shadowcliff Mountain, located in Grand Lake is a non-profit lodge and retreat center that offers affordable cabins, and a hostel. Relax at these peaceful accommodations after a busy summer day in the Park.

Fishing: Trout fishing in the lakes and streams of Rocky Mountain National Park is one of the most popular activities in the summer 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.

Horseback Riding: Horses have long been a traditional part of Rocky Mountain National Park. In fact, 260 miles of trails are open to horse use. There are two stables located within the park: Glacier Creek Stables and Moraine Park Stables which are open for private and commercial horse use. Plan your route and check the trail conditions if you plan to travel this way.

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.

Rock Climbing: Whether it be bouldering, big wall climbing, or mountaineering, Rocky Mountain National Park is a popular location for climbing. Longs Peak is a desirable climb for many. There are several rules and regulations for climbing within the Park boundaries, and it is always imperative to follow leave no trace principles when entering the backcountry.

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 August 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.

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.  All paved roads are open to cyclists, but bear in mind that there will be a large number of cards on the roads in the summer, so be careful. In August, you can bike on Trail Ridge Road and Old Fall River Road for a nice challenge. Keep in mind that Trail Ridge Road gains over 4,000 feet over elevation over its 48 miles and 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.
