The first day of fall is next week, but the leaves have already started turning.

Many people are wondering where to go to see the best colors, so here is our guide to the gold!

Here's a list of Denver7's favorite places to see the golden colors in Colorado:

1. Kenosha Pass

Kenosha Pass on Highway 285 between Grant and Jefferson is popular with leaf watchers and photographers because you can get amazing shots right from the highway. The Colorado Trail crosses Highway 285 here so you can hike in either direction and be in the fall colors.

2. Guanella Pass

Guanella Pass between Georgetown and Grant gives fall color searchers a chance to see the colors at elevations between 9,000 and above. While the pass hits a high of 11,670, the pass is home to a 14,000-foot peak (Mt Bierstadt), so you can see the colors turning over a wide variety of elevations. With hillsides full of Aspen trees on both sides of the pass, this is a popular area for photographers.

3. Maroon Bells

The Maroon Bells, near Aspen, but may be a bit of a drive from Denver, but thousands make the drive during the fall to take a photo of the Maroon Bells with the turning leaves reflecting in Maroon Lake. Because this area is so popular with visitors and photographers, the road is open to shuttle buses only from 8 a.m. to 5 p.m and there is a fee. Learn more here.

4. Como, Colorado

Como is on Highway 285, past Kenosha Pass. It's a nice drive to take Boreas Pass from Como to Breckenridge.

5. Rocky Mountain National Park

The leaves are turning around Rocky Mountain National Park.

Two of the most popular fall color hikes are the trail to Bierstadt Lake and Alberta Falls (see above). Check with the park rangers for their advice on where to go.

And here is Mike Nelson's list of his top 22 locations for fall colors:

  1. Steamboat Springs, Elk River country north on County Road 129.  Also, check the view on Rabbit Ears Pass and Buffalo Pass east.
  2. Colorado 14 through the Poudre Canyon west of Fort Collins
  3. Trail Ridge Road (US 34) through Rocky Mountain National Park
  4. Flat Tops country between Buford and Newcastle
  5. Tennessee Pass, US 24, from Leadville to Vail
  6. Boreas Pass between Como and Breckenridge, a 23-mile road cresting at 11,481 feet.
  7. Guanella Pass between Georgetown and Grant

Why the colors change

Perhaps the most appealing part of autumn is the gold found in the mountains each year. Not the gold sought by prospectors over a century ago, but rather the gilded glory of Colorado's famous aspen trees. The decrease in sunlight switches off the mechanism in the leaves that creates chlorophyll - the green color in the leaf.

As the green fades, the gold color dominates until dying leaf flutters to the ground.  The best years for aspen viewing are those with well-timed rains and no major fall storms. A too dry summer will send the leaves falling quickly, while a wet summer tends to make them darken to brown or black.

The most brilliant display of aspen occurs when we have a mild late summer and periodic gentle rain, combined with a dry September that includes few big windstorms or early snows.

Usually, the first signs of aspen gold begin in mid to late August over the higher forests of central and northern Colorado. By the second and third week of September, many aspen groves are well worth a day's drive. Usually, the peak time to view aspen is around the last weekend of September.

After that, early snows will knock down the leaves and others drop away by themselves. Aspen color does not vary nearly as much as the rich reds and purple leaves of the Midwest and East, but there is something about gold leaves against a backdrop of rich evergreen and deep blue sky that makes our fall mountains special indeed!

About the trees

Nothing says "autumn" in Colorado quite like the sight of a mountainside covered in the stunning leafy gold of aspen trees. Colorado's famous high country aspen reliably turn gold from the second week of September through the first week of October.  Populus tremuloides - or the quaking aspen - can be found in all eleven of Colorado's national forests and their autumn fireworks are worth the drive.

Aspen naturally propagates in areas where hardier trees have been damaged or destroyed. This was the case in Colorado, where the slender trees grew in after logging stripped trees from mountain areas. Characterized by their elaborate root systems, aspen reproduce by sending up suckers from the roots to create "clone" stands of trees. These clones, connected underground at the root, are genetically identical to the mother tree. The identical nature of a clone stand is most obvious in springs, when each tree in the stand leafs at the same time, and in fall, when each tree turns the same shade of gold.

Historically, native tribes used the aspen bark to make medicinal teas to alleviate fever. The inner bark was sometimes eaten raw in the spring, and the outer bark occasionally produces a powder that was used as a sunscreen. Aspen is a favorite of Colorado wildlife too. Beavers use aspen for food and building; elk, moose, and deer eat the twigs and foliage. Other names for quaking aspen are golden aspen, mountain aspen, popple, poplar and trembling poplar.

Despite Coloradans' affinity for aspen, these delicate trees are not highly recommended for residential landscaping, especially at lower elevations of the state. Aspen as susceptible to many diseases, their convoluted root systems often grow into sewage drainage systems, and they generally last no longer than about 10 years out of their native habitat.
