It's time for your Week 4 Fall Foliage Report! 🍁🍂

Recent cold nights have sparked dramatic color changes across Pennsylvania’s forests, and now vibrant hues are bursting statewide. From the Poconos to the Allegheny Plateau, across the full sweep of the Appalachians and into the southeastern corners of the state, the autumn cheer of Penn’s Woods is on full display.

It’s shaping up to be one of the most impressive fall foliage seasons in a few years, making right now the perfect time to get outside and enjoy Pennsylvania’s breathtaking autumn scenery!

It's time for your Week 3 Fall Foliage Report! 🍁🍂

While heavy rain knocked down some leaves, chilly nights recently sped up the color change in many Pennsylvania forests. The cooler weather expected this weekend will help bring out even brighter fall colors across the state.

With beautiful shades showing up everywhere now, it’s a great time to get outside and enjoy the stunning fall scenery in the Keystone State!
