When is the best time to visit Rocky Mountain National Park?

Rocky Mountain National Park is open all year round, but the best time of year to visit depends on what you want to do! The park is busiest from June to August, so if you’re looking for fewer crowds, winter is the best time to visit. 

If you want to see the fall colors, October is definitely the best time of year for you. Summer is a great time to enjoy the outdoors, but everyone is on summer break, and the park is swarmed by tourists. Spring is a good time to go to see flowers, but the weather can change easily. 

My personal recommendation? Winter is the best time to visit Rocky Mountain National Park. Though the weather can be cold, you’ll basically have the trails to yourself, and it’s so easy to get parking.

Best time to go to Rocky Mountain National Park by type:

• Fewest crowds: The best time to visit Rocky Mountain National Park to experience fewest crowds is in the winter.
• Best for hiking: Hikers should visit Rocky Mountain National Park in the spring or summer months for hiking, but be sure to start early in the day before timed entry passes are needed.
• For camping: The greatest time of year to visit Rocky Mountain National Park for camping is in the summertime. The weather is basically perfect but be warned that the park can get quite crowded during this time.
• Best weather: The best weather (that’s a bit more reliable) at RMNP is in the fall!

Visiting Rocky Mountain National Park by the Season

What time of year should you visit Rocky Mountain? Here’s a breakdown by season.

Spring in Rocky Mountain

Rocky Mountain National Park is a beautiful place to visit in the springtime. The weather is mild, and the landscape is covered in a beautiful blanket of wildflowers. There are also plenty of outdoor activities to enjoy, such as hiking, biking, and fishing.

The temperature fluctuates throughout the year, and can be drastically different than Denver, which is only 1.5 hours away! Spring temperatures can reach as high as 50° but lows of 23° at night. It’s also not always sunny; we’ve visited and gotten a snowstorm in spring.

Pros & Cons of Visiting Rocky Mountain in the Spring:

• Pro: The park is starting to come alive again, and lots more color is added to the park after winter.
• Pro: There aren’t always large groups of visitors like you’ll witness in the summer.
• Con: You can get stuck in a snowstorm; be sure to check the weather.
• Con: Trail Ridge Road is closed for most of the spring.

Rocky Mountain Spring Activities:

• Hike in the lower parts of RMNP, such as East Inlet Trail, Deer Mountain, or Ouzel Falls.
• Be on the lookout for wildlife. You might see elk, deer, or even otters during the spring months.
• Find wildflowers that are in bloom between April and May. Many wildflowers can be found on the Nymph Lake Trail.
• Go fishing! Be sure to have a Colorado Fishing License.

Tips for Visiting in the Spring:

• Pack lots of water and snacks.
• Wear layers because the weather is unpredictable in the spring.
• Get to the park early to avoid the crowds, especially on days that happen to be warm.
• Bring spikes for your shoes. Lots of the trails end up still being icy or snowy.

Summer in Rocky Mountain

Visiting Rocky Mountain National Park in the summer is an experience like no other. With average temperatures between 70 and 90 degrees Fahrenheit and many sunny days, the weather is perfect for exploring its varied landscapes and abundant wildlife.

During summer, people flock to the park to take advantage of its hiking trails, scenic drives, and camping opportunities. Plus, you can enjoy activities like fishing, horseback riding, rock climbing, mountain biking, and more.

Keep in mind that the summer is the absolute busiest time of year to visit Rocky. Because of that, you NEED to get there early. You also need to make a park reservation, because this is when timed entry is in effect, unless you visit before the park opens (which we highly recommend).

Pros & Cons of Visiting Rocky Mountain in the Summer:

• Pro: The beauty of the park is at its peak, with lush vegetation and animals roaming around in their natural habitat.
• Pro: The snow is mostly gone from all the trails.
• Pro: Trail Ridge Road is open for a scenic drive!
• Con: Temperatures can get very hot during this time of year, which could make outdoor activities difficult or uncomfortable. Start in the morning to avoid this.
• Con: Due to the popularity of visiting during this season, there are often large crowds of tourists which can detract from your overall experience.

Rocky Mountain Summer Activities:

• Hike to the top of Long’s Peak, but only if you’ve experience with hiking 14ers. Remember to start early in the day to avoid thunderstorms.
• Go camping in one of Rocky’s campgrounds.
• Go on a scenic drive along Trail Ridge Road. The highest continuous paved road in North America provides stunning views as it winds through Rocky Mountain National Park’s alpine tundra and wildflower meadows.
• Take part in ranger-led activities. Rangers offer guided walks and talks during peak season, where visitors can learn more about the park while also enjoying its natural beauty.
• Catch the sunrise up at Lake Haiyaha. Get there right at the predicted sunrise (use the weather app on your phone to see when this is) to catch the best view of your life!

Tips for Visiting in the Summer:

• Dress in layers, as the weather can change quickly, even during the summer months.
• Bring plenty of water and snacks to stay hydrated and energized during your visit. Water bladders are a great option because they can hold lots of water right on your back.
• Wear sunscreen and a hat to protect from the sun’s rays at high altitudes.
• Hike early in the morning or late in the evening when temperatures are cooler.
• Make your timed entry reservation well in advance.

Fall in Rocky Mountain

The Rocky Mountains in the fall are a must-see! The average temperature ranges between 35 – 65 degrees Fahrenheit, making it the perfect destination for those looking to get away from hot summer temperatures and enjoy a cool vacation.

During the fall, thousands of people still come to visit the Rocky Mountains, taking advantage of mild days and the beautiful scenery. Colorful leaves, crisp air, and outdoor activities like camping, fishing, hiking, biking, and more make it an ideal spot for all types of adventurers.

Keep in mind that this time of year the park does start to see snow. You’ll want to plan wisely. The winds can also be a lot worse than you might think during the fall months!

Pros & Cons of Visiting Rocky Mountain in the Fall:

• Pro: Crisp, cooler temperatures allow for you to be more comfortable while outdoors.
• Pro: Beautiful changing colors of the fall foliage will take your breath away.
• Pro: There are reduced crowds compared to the summer months
• Con: There are limited daylight hours due to early sunset.
• Con: There is possible snow at higher elevations that may limit access to trails and roads
• Con: Some areas may be closed completely due to snow or inclement weather.

Rocky Mountain Fall Activities:

• Hike in the mountains and take in the stunning views. Great hikes during this time include up to Emerald Lake or around Sprague Lake.
• Visit one of the park’s many waterfalls and enjoy the scenery. Alberta Falls is a great option.
• Look out for fall foliage throughout the park. It’ll take your breath away!

Tips for Visiting in the Fall:

• Pack layers of warm clothing and sturdy, waterproof shoes for unpredictable weather conditions.
• Bring along a pair of binoculars or a camera with a long lens to better view wildlife from a distance.
• Be prepared to encounter fewer tourists than in peak season but more wildlife such as deer and elk migrating through the park in fall months.
• Consider visiting early in the morning when temperatures are cooler, making it easier to explore longer distances on foot trails or roads while avoiding afternoon thunderstorms commonly seen in autumn months at Rocky Mountain National Park.

Winter in Rocky Mountain

Rocky Mountain National Park is a beautiful place to visit year-round, but winter brings its own special kind of magic. During the winter months, the average temperature in Rocky Mountain can range from 18°F to 36°F, but can often even go lower.

Although the cold weather may seem daunting at first, visitors are often surprised by the beauty of snow-covered mountains and frozen lakes. The park also sees fewer visitors during this time of year, making it ideal for those who prefer more peaceful outdoor experiences. (Winter is easily our favorite time to visit, with popular trails like Emerald Lake Trail being basically empty.)

Not only does visiting Rocky Mountain in the winter offer an opportunity to reconnect with nature, but it often brings a chance to try out fun activities like skiing and snowshoeing as well. So if you’re looking for a chance to get away and experience nature in all its glory, then consider visiting Rocky Mountain during the winter months!

Pros & Cons of Visiting Rocky Mountain in the Winter:

• Pro: There are beautiful snowy landscapes and fewer crowds.
• Pro: There is a chance to explore a different perspective of the park, with snowshoeing, skiing, and other cold weather activities.
• Pro: The trails are practically empty, just with other tourists who are getting out to enjoy nature.
• Pro: You don’t have to get a timed entry pass, and it’s pretty easy to find parking.
• Con: Roads may be closed or dangerous due to icy conditions. For instance, Trail Ridge Road is always closed in winter.
• Con: Temperatures can drop to extreme levels.
• Con: There are fewer amenities available during the winter months. For instance, a lot of the visitors centers close.

Rocky Mountain Winter Activities:

• Bring a pair of snowshoes and enjoy the wintery trails.
• Enjoy a winter hike on one of the park’s many trails. Emerald Lake is our favorite in the winter, but it can get icy.
• Take photos of frozen waterfalls and other winter wonders.

Tips for Visiting in the Winter:

• Prepare for extreme weather conditions; dress appropriately with warm layers, waterproof outerwear, and insulated footwear.
• Be aware of avalanche risk on higher elevation trails.
• Pack snacks and water for the day, as some facilities may be closed due to inclement weather.
• If you plan to go snowshoeing or hiking, make sure you are familiar with the trails before setting out, and carry a map with you at all times.
• Make sure your vehicle is winterized and equipped with emergency supplies in case of an unexpected breakdown.
