When do Aspen trees change color at the higher altitudes?
 

We will be driving in the mountains near Denver next week... too early for the higher altitudes?

Here's a site you can try:

its a year to year thing and i am in maine now but i think you will get to see some color. may depend on how high you are going. the temp in leadville tonight will be about 34...

We were in Aspen on Sept. 26/27 in 2002 and it was wonderful. When you go to visit the maroon bells its one of the most beautiful sites imaginable. Also the road from Durango to Gunnison was amazing. Paul

I AM SO EXCITED!!!!
I leave Weds morning and I get to put in 6 hour days and cruise around the Denver area a few days and spemd a whole weekenddrivingup into the mountains.
I just love Colorado!

The color amount and time varies every year, but it's always beautiful. I have to get busy planning my annual color trip!
