When Does Foliage Peak in Vermont
During the spring and summer, maple leaves supply energy to the tree, using chlorophyll to turn sunlight into sugar. In the fall, cooler temperatures and fewer daylight hours are the leaves’ signal to stop making energy, breaking down the chlorophyll and allowing other pigments in the leaves, such as red and orange, to take center stage. Finally, an abscission layer forms near the end of the fall foliage season when temperatures are colder, creating a wall in the leaf and disconnecting it from the tree, making it easy for wind and rain to drop the leaf to the ground.
All that chemistry means during the “peak weeks,” Vermont’s forests blaze with red, orange, and yellow maple trees, leaves crunch under your feet, and the whole state is a riot of autumn color. Vermont’s dense forest covers 70% of the state, meaning you’ll be able to count on beautiful fall views during the week preceding and after peak foliage too, depending on weather conditions and geographic location within the state. Heavy wind or rain and drought earlier in the year can impact when and how colors unfold and how long they stay on the trees.
The rule of thumb is that color usually starts in early to mid-September in the higher elevations and in the northern part of the state, moving into the valleys and southern parts of Vermont as September turns to October. Leaves can hang on until the last week of October or the first week of November, although most will be on the ground by then.

Road tripping around Vermont in the fall can also yield some stunning leaf peeping as colors change depending on tree species, elevation, temperature, and conditions in that area. Looking for the best route to see fall color? Plan a scenic drive along a river as the foliage reflects off the water and over a mountain pass as it connects from town to town. Scenic Vermont Byways and toll roads open to expansive mountain vistas painted in fall colors. Enjoy apple orchards, pumpkin picking, scenic chairlift rides, corn mazes, farm or creemee stands, and historic downtowns round out a day touring around the Green Mountains.
