THE WEST SIDE OF ROCKY MOUNTAIN NATIONAL PARK

Check Rocky Mountain National Park’s current reservation requirements and make your reservation at Recreation.gov.

If you have never been to Rocky Mountain National Park, you’re in for an extraordinary experience. This national park hasn't changed much over the years. With its rolling tundra, stoic mountain peaks, glacier-carved valleys and abundant wildlife, the same things that made this place special in 1915 when it was declared a national park continue to make it special today. But with the park's staggering 416 square miles, it can seem a little daunting to know where to start. Get a beginner’s guide to Rocky Mountain National Park below.

The Lay of the Land

Rocky Mountain National Park has two distinct halves, which are connected by the highest continuously paved road in North America: Trail Ridge Road. No trip to the park is complete without driving the 48-mile road in its entirety. However, it is important to note that the road is closed in winter due to snowpack.

The eastern slope of the park includes notable attractions like Longs Peak, Moraine Park, Bear Lake, Wild Basin and Sprague Lake, and as a result, it is the more heavily trafficked side of the park.

The western slope of the park features Colorado's largest natural lake (Grand Lake), an expansive valley abundant with moose and elk (Kawuneeche Valley), the headwaters of the Colorado River, and more than a dozen backcountry valleys perfect for horseback riding and hiking excursions.

Know Before You Go

Public lands are the heart and soul of Colorado, providing a stunning natural backdrop for outdoor recreation and a haven for wildlife. They are measured in more than just acres — they are the memories we make, the moments we cherish and the natural wonders we protect.

So as you explore Rocky Mountain National Park, be sure to follow Care for Colorado Leave No Trace Principles to ensure its beauty remains unspoiled for future generations.

Follow the “rule of thumb”. If you can cover the animal with your thumb, you're at a safe distance. Store food, trash and scented items in bear-proof containers to avoid unwanted interactions.
Stay on designated trails, even in less-than-ideal conditions. It protects wildlife, prevents erosion and ensures you remain on the safest terrain. If you're camping, choose a designated campsite.
Ensure campfires are permitted in your area. Once lit, keep them small and monitored, and extinguish fully when finished. Be careful when smoking, discarded butts are common causes of wildfires.
Always pack out your trash, including peels and cores. No restroom? Be ready with a disposable WAG bag or bury your business 8 inches deep, at least 70 steps from all water sources and trails.
Never take plants, rocks or cultural items you find while exploring. Keep gear clean to prevent the spread of invasive species and preserve the landscape. Even minor damage can have a lasting impact.
Respect fellow adventurers in Grand County. Be mindful of noise and yield to uphill hikers and bikers who need the momentum. Always give priority to wheelchair users and equestrians on the trail.
Grand County weather is as varied as our activity options. Be prepared with warm layers, sun protection and a reusable water bottle to stay hydrated. Explore lesser-traveled sites to avoid the crowds.

Where to Stay

The park's two main gateway towns — Grand Lake and Estes Park — are not short on hotels, motels, inns, bed-and-breakfasts and vacation rentals. As a result, either works as a great basecamp for your first adventure.

Grand Lake's accommodations offer the added bonus of access to such outside-the-park attractions as Shadow Mountain Lake, Lake Granby, the Indian Peaks Wilderness, Winter Park, Fraser and Hot Sulphur Springs. Nearby, Granby and Kremmling also offer a variety of authentic Colorado lodging options, and they are only a short drive from the park.

If you are looking to camp, the park offers five campgrounds of various sizes, with all but the Longs Peak Campground accommodating RVs. The Timber Creek Campground on the west side of the park lies in the heart of the Kawuneeche Valley, and its spacious 98 camp sites are peaceful and scenic.

When to Visit

Rocky Mountain National Park offers plenty of contrast from one season to the next. Summer (generally Memorial Day to Labor Day) is peak visitor season for good reason — trails are snow-free, the park's wildlife is active, and the wildflowers are in full bloom.

But ask a local or frequent visitor to the park, and they will tell you that autumn (generally Labor Day to mid-October) is their favorite time of year. While you may see an early snowstorm during this season, you are more likely to see the aspen trees and tundra grasses turning their vibrant shades of gold and red, and you are also likely to hear elk bugling during their annual rut season. Trails often remain accessible, and most campgrounds remain open during this time as well. Check out our top five places for fall colors for even more itinerary ideas.

In winter, Trail Ridge Road (which connects the eastern and western halves of the park) closes due to snowfall, and the park sees little visitation. But for outdoor enthusiasts looking to cross-country ski or snowshoe, the park's valleys and trails are a sublime winter wonderland where you can see fresh animal tracks, frozen waterfalls and snow-covered peaks.
