Best Time to Visit the Black Canyon of the Gunnison: Weather & Events

When is the best time to visit this dark, deep purple gorge wall in the remote Colorado wilderness?

During my own 5 month road trip through the Rockies, I found myself at this Western Colorado national park during March, not the best month by any means. Still covered in snow and because of the road closures, I didn’t see a single soul for the half day I was there. Plus, it was pretty cold outside. 

The climate at Black Canyon of the Gunnison National Park can range from hot, dry summers to brisk winters. So, here’s a snapshot of the visitor seasons at Black Canyon:

• Peak Season: May to September 
• Shoulder Seasons: April to May and September to November 
• Off-Peak Season: November to April

In the upcoming section, I’ll dig into all the details about each season, nearby must-experience events, and a monthly weather breakdown. Whether you’re planning a one day visit to the Black Canyon or a longer stay, driving the South Rim or North Rim, these are the best and worst times to go to the Black Canyon of the Gunnison National Park.

Best Time to Visit Black Canyon of the Gunnison National Park

Best Time of Year to Visit

The best time to visit Black Canyon of the Gunnison National Park is from May to September, during the peak season. It’ll be warm now and all the park’s hiking trails and facilities are open. W

ith the abundant sunshine illuminating the dark gorges, the contrast creates dramatic shades in the valley, and you’ll be able to jump in or do more water activities.

Best Time for Good Weather

For the best weather, summer is again the winner. You’ll experience warm temperatures between 70 to 85 degrees Fahrenheit under predominantly sunny skies. Although not overly hot, the sun can be intense at these high altitudes!

Best Time for Smaller Crowds

Black Canyon of the Gunnison National Park is a relatively underrated national park, so it’s never crazily crowded, especially the lesser-visited North Rim. If you want even fewer people but still have comfortable weather, come during the shoulder seasons, especially around late April or October.

During these months, the park sees significantly fewer visitors, with numbers dipping to an average of 15,000 – 25,000 people per month, compared to the peak season average of 50,000. 

The smaller crowds are because most of the roads are closed from November to April, and it is cold outside. In March, I still donned my full winter gear. 

Cheapest Time to Visit

The most affordable time to visit Black Canyon of the Gunnison National Park is during the off-peak season, from November to April. During these months, local accommodations and travel costs can drop by around 20% to 30% compared to peak season rates. However, be prepared for possible road closures, wintry weather conditions, and campgrounds may be closed.

Best Time for Stargazing

If you’re into stargazing, the best time to check out Black Canyon of the Gunnison National Park (an International Dark Sky Park) is during the new moon phase in the summer. 

The skies are super clear then, and the park’s remote location means less light pollution. You’ll get an amazing view of the Milky Way and tons of constellations. Remember to bring a blanket and a thermos of hot chocolate for those chilly, starry summer nights!

Worst Time to Visit

The worst time to visit Black Canyon of the Gunnison National Park is during winter, specifically from mid-November to April. During this period, heavy snow and ice result in road and trail closures. 

The chilly temperatures often drop below freezing, not leading to a comfortable outdoor experience. When I went, the trails I hiked near the visitor center were slick with ice.

Park Closures

Black Canyon of the Gunnison National Park is technically open 24/7, 365 days a year. However, due to weather conditions, major road closures happen between November through April.

The South Rim Road past the visitor center, North Rim Road, and East Portal Road all typically close from mid-November until early April. You can visit up to the visitor center area, which is open year-round. 

Seasons at Black Canyon of the Gunnison National Park

Spring (March – May)

Springtime at Black Canyon of the Gunnison National Park can be a mixed bag, with the first hints of warming weather in April. Early spring, particularly in March, can still see snowfall and icy conditions, especially on North Rim Road and East Portal Road. 

By April, the temperatures rise steadily to 50-60 degrees Fahrenheit during the day. The melting ice off the canyon walls creates waterfalls on the gorge. 

Although it is more than in winter, only a few people visit until May. Sections of the park are still on their seasonal closure. Only the South Rim to the visitor center area is accessible.

Summer (June – August)

Summer is the peak season at the Black Canyon of the Gunnison National Park. The weather is 75 and 85 degrees Fahrenheit, and all roads and trails are open.

The park buzzes with life during these months. There are way more visitors in July and August especially, and you’re more likely to see more wildlife. Besides hiking and stopping at the overlooks, you can enjoy water activities at the end of the winding, steep roads leading to the river.

Mountain weather can be unpredictable, and summer storms can roll in quickly. Always check the forecast before you go.

Fall (September – November)

As the summer heat eases off, September ushers in cooler temperatures that fluctuate between 60 and 70 degrees Fahrenheit, dropping to chillier levels as the season progresses.

The fall foliage starts peeking through in late September, reaching its peak in early October. The canyon is awash with the vibrant yellows of cottonwoods and the reds and oranges of scrub oaks. Wildlife sightings are also common in this season as animals prepare for the winter.

As fall transitions into winter, there’s a potential for early snowfall, especially in late November.

Winter (December – February)

Winter in the Black Canyon of the Gunnison National Park is a season for the adventurous and those who love snow. The crags of the towering black cliffs of the canyon are covered with a blanket of snow, and the visitation numbers drop to a couple thousand per month.

During these chilly months, the temperature bottoms to 20 to 40 degrees Fahrenheit during the day and further at night. Snowfall varies across the park, with the South Rim often receiving less than the North Rim. Consequently, the South Rim Road remains open to Gunnison Point. The North Rim Road and East Portal Road close for the season.

Cross-country skiing and snowshoeing become popular on the South Rim. But the trails get very icy. If you plan on hiking, I wouldn’t go without crampons.

Best Time of Day to Visit

Even though it was quite cloudy the day I went, I think mid-day would be the best time of day to go to Black Canyon of the Gunnison National Park. I’m sure the sunsets are beautiful as well, but the canyon is super deep, so the only time it is not in shadow is when the sun is high in the sky. 

At this elevation and latitude, it’s also the warmest part of the day for outdoor fun.

Here’s a breakdown of what you can expect by time of day:

• Morning (6 AM – 10 AM): The park is not that crowded. As the morning sun gradually kisses the canyon walls, you’ll see a beautiful change of colors.
• Mid-Day (10 AM – 2 PM): The sun is at its peak, the canyon is fully illuminated, and the temperatures are ideal for exploring.
• Afternoon (2 PM – 6 PM): The canyon is bathed in a warm, golden light as the sun sets. Wildlife become more active.
• Evening (6 PM onwards): Most people just spend a day here, but once the sun has set, the park transforms into an excellent spot for stargazing.
