As the days grow shorter and a cool, crisp breeze fills the air, it can only mean one thing – fall is here. And in the picturesque state of Colorado, this change in seasons brings with it a breathtaking transformation that photographers simply cannot resist capturing.

Here’s a quick guide to when to expect Colorado fall colors to peak in the front range and Denver area.

Note: these are estimates only - weather, early storms, windy days etc all affect foliage.

Rocky Mountain National Park - Mid to end of September

Summit County - Late September to Early October

Northern/Southern San Juan Mountains - Late September to Mid October

Denver - Early to Late October
