Summer, we love you, but we’re getting pretty pumped for fall. There are so many things to look forward to: the return of sweaters, pumpkin spice lattes (and M&Ms?) and of course, those gorgeous falling leaves. They’ve made many a pretty Insta photo and they’ll definitely be the backdrop for oh-so-many autumnal outdoor weddings. But the US is a big place, so how can you be sure that your ceremony will be surrounded by multicolored leaves and not just naked branches? Well, for starters you can use this handy map.

The Smoky Mountain’s website has released an interactive map on their website that shows exactly when + where in the country leaves will be at their prime. It turns out that in most states, peak season falls between September 26th and October 17th. If you’re planning on getting hitched under the trees ASAP, you probably want to head to states like Montana, Idaho and Colorado where the changes happen the earliest. By October 17th, most of the country is at partial, near peak or peak change. If you wait until November, you can only really head to the southeast to find leaves that are still changing.

Now that that’s settled, let’s get started on the rest of the planning!
