If you dream about visiting Aspen, Colorado, there’s no better month than September when the fall colors are in full glory. Aspen marks the transition from summer to fall with the first half of the month bringing plenty of warm, sunny days, and the second half getting cooler temperatures.

The middle to the end of September is when you can see the most spectacular fall colors, so if you plan on visiting Aspen in September, bring your camera! As temperatures get cooler, thousands of Aspen trees turn gold, creating a stunning display of colors. 

The first Aspen trees that begin to change their colors are those at the higher elevations, with the trees at lower elevations waiting just a bit longer to show off their fall palette.

It’s important to remember if you are coming to Aspen to take fall photos.



Although September sees the first cool days in Aspen, it’s still a bit too early for the first snow which usually falls in October at higher elevations around Aspen mountains. 

Since the cold season is not yet here, it’s more common to see fall foliage and changing colors in the mountains during this time, rather than snow. Still, Aspen weather in September can vary, and while it’s unlikely to see snow in Aspen in September, unexpected weather can occur.

Aspen has mild and pleasant weather in September, marking the transition from summer to fall. Still, weather conditions can vary from year to year. September has daytime temperatures ranging from the mid-60s°F (around 18-20°C) to the mid-70s°F (around 23-25°C).

The evenings can be cooler, with temperatures dropping into the 40s°F (around 4-9°C). It’s a good idea to layer your clothing for the temperature changes throughout the day.

September has lower chances of rain, unlike summer months. However, occasional rain showers or even early-season snowfall can occur, so pack a light jacket or raincoat.

Best things to do in Aspen


With gorgeous fall colors on full display, September is the best time to enjoy Aspen. From hiking to mountain biking and attending local events, there are plenty of things to do in Aspen in September. 

1. Visit the Maroon Bells

The iconic Maroon Bells are two majestic peaks just outside Aspen. Take a hike or bike ride in the area to enjoy the stunning fall foliage. September is the best time to see the Maroon Bells in their full glory, 

September is also the busiest time at Maroon Bells when photographers from all over the world come here to snap photos of the majestic mountains framed by the golden Aspen trees. 

If your goal is to take photos of the Maroon Bells, here are a couple of tips for you:

  • Plan your trip for a weekday – Most visitors come on weekends, so if you want to have a better experience, visit Maroon Bells on a weekday, when it’s less crowded.
  • Come after the sunrise – Most photographers come to Maroon Bells before sunrise to capture the moment when the first rays of sun light up the iconic peaks. The area can be extremely crowded, and if you show up 10-15 minutes after sunrise, you will have a lot more space and much better experience.
  • Bring a tripod – Since the light is still low during this time, I recommend taking photos on a tripod. 

2. Go for a hike

Aspen offers numerous hiking trails suitable for all levels of hikers. Some popular trails include the Hunter Creek Trail, Ute Trail, and the Rio Grande Trail.

3. Attend festivals

September in Aspen is known for its vibrant festival scene. Look for events like the Jazz Aspen Snowmass Festival or the Aspen Filmfest, which showcase music, film, and culture.

4. Visit the Aspen Art Museum

Explore contemporary art at the Aspen Art Museum, which has rotating exhibitions of established and emerging artists. Visiting Aspen Art Museum is a perfect idea for a fall day when the weather is less ideal for hiking and exploring. 

5. Relax in the hot springs

Soak in the natural hot springs near Aspen for a rejuvenating experience. Popular options include the Glenwood Hot Springs and the Avalanche Ranch Hot Springs.

Book a stay at Glenwood Hot Springs Resort, where you can enjoy one of the best hot springs in Colorado.

Drive the pass from Leadville, the highest mountain town in the United States with an altitude of 11,000 feet. Leadville has an interesting mining history and is also near Twin Lakes where you can camp, kayak, and paddle board.

7. Crystal Mill

Also known as the Old Crystal Mill or the Sheep Mountain Powerhouse, this historic landmark was built in 1892 and served as a power source for nearby silver mines and later for a hydroelectric plant. Today, it’s a well-preserved landmark about a 45-minute drive from Marble and approximately 1.5 hours from Aspen.

➡️ The Crystal Mill is not easily accessible by car, and you need to rent a 4X4 to get there.

The road leading to the mill, known as the Crystal River Jeep Trail, is rough and recommended for experienced off-road drivers. You can also reach the mill by hiking or biking along the trail, which adds more adventure to your tirp.

1. Visit Aspen after September 15

Although you can see the first fall colors in Aspen in early September, you will see more of them during the second half of the month when more Aspen trees will show their colors.

This is especially true if you are visiting Aspen during the first half of the month when there isn’t as much fall color at lower elevations. There are several scenic passes around Aspen like Independence Pass and Kepler Pass where you can see more golden trees in early September if you can take a drive.

3. Rent a car

If you want to enjoy the best hiking trails in Aspen and surrounding areas and see the golden aspens, you need a car rental. While Aspen has a good public transportation network, you need a vehicle to get to most hiking areas.


4. Or get a rental bike

Aside from renting a car, you can explore many Aspen groves surrounding Aspen by bike. Aspen Mountain ski resort usually opens in November, while Snowmass and Buttermilk ski resorts near Aspen open in late November-mid December.

7. Stay hydrated

I can’t stress enough how important it is to stay hydrated on your trip. Aspen is located at an altitude of 7,908 feet (2,400 meters) and if you are not used to the high elevation, you can quickly develop symptoms of altitude sickness.

Drink plenty of water, and make sure you are used to the altitude before attempting hikes at higher elevations.

If you want to enjoy scenic passes around Aspen and explore the area, you will need a car rental. You can rent a car in Aspen and surrounding areas, but do it ahead of your trip, because September is a busy season, and it’s not uncommon for rental car companies to run out of cars during this time.
