When is the Best Time to Visit Great Sand Dunes National Park?

The best time to visit Great Sand Dunes National Park is in the Spring and Fall. During May and early June, and September and October, you can avoid the peak crowds, and take advantage of cooler weather. The sand can get quite hot in the summer months- the creeks dry up, giving you little respite from the blazing sun.

Great Sand Dunes National Park is open year-round, but the visitor center and campground are only open from April through October. The peak season is May through August. Medano Creek’s peak flow is from late May to early June and is very popular with tourists and kids.

We visited at the end of July. The creek was still running but was only a few inches deep at the extremes. We arrived around noon and after checking out the Visitor Center, we headed to the Sand Ramp Trail Head in the Piñon Flats Campground. The hike is just about a mile to the Dunes Overlook, but it gave us a nice overview and got the kids excited about sand sledding the following day.

Spring in Great Sand Dunes National Park

Spring in Great Sand Dunes can be volatile with blustery conditions. Plan to visit the dunes in the morning to avoid the higher winds. March and April are the snowiest months of the year on average, with temperatures in the forties and fifties during the day and below freezing at night. Snow falls on the dunes about once a week, but it melts within a day or two.

The creek is still mostly frozen to the east of the dunes, but the main roads are usually quickly plowed.

Early February to late March is a great time to see Sand Hill Cranes migrate to the park. You’re also most likely to see Elk in the part in these cold months.

Piñon Flats Campground opens for the season around the beginning of April and starts to fill up by the end of the month as the weather continues to warm up.

Summer in Great Sand Dunes National Park

By the end of June, Medano Creek starts to recede and is dry through July and August. At this time, the park is bustling with visitors. Weekends this time of year are extremely crowded with long lines to get into the park, overflowing parking lots, and full campgrounds.

If you visit during summer, try to avoid weekends and arrive early to avoid the long lines at the entrance. Arriving early will also allow you to beat the heat, as July and August are the hottest months in the park with daily temperatures in the upper seventies and low eighties.

In July and August, afternoon thunderstorms regularly bring lightning, wind, and heavy rain. But with the rain also comes wildflowers and by the middle of August, the grasslands and hills around the dunes are covered in prairie sunflowers.

Fall in Great Sand Dunes National Park

Autumn is a wonderful time to visit Great Sand Dunes National Park. September is still rather warm with temperatures ranging from the low seventies in the day to the mid-forties at night with mostly clear skies and calm weather.

The aspens turn color throughout the month and come October are at their peak golden color. Cottonwoods peak around the middle of fall and snow showers begin to dust the surrounding mountains.

While there is no hunting around the sand dunes, remember that the fall may be hunting season and if you are hiking up in the hills, be sure to wear bright colors. Most hikers, however, do not see any hunting activity.

Winter in Great Sand Dunes National Park

Great Sand Dunes in winter is relatively quiet, with almost weekly snowfall and temperatures often below freezing. Most days though are sunny and calm. Around the holidays, and after a snowfall, you can often find people cross-country skiing or sledding on the dunes.

Temperatures in Great Sand Dunes in winter varies, with lows dipping into the 20s (F). Expect snowfall about once a week, with the most snowfall in March and April.
