Outdoor Adventures

September is one of the most beautiful times to get outdoors in Maine — cooler mornings, bright afternoons, and trails alive with early color. If your family loves exploring together, this month has plenty of options to get those sneakers (or little boots!) moving.

Explore Rolfe Hill Forest
The Rolfe Hill Forest Loop in Casco is a local favorite for an easy family hike. With shady woodland paths, interpretive signs, and peaceful views, it’s the perfect introduction to hiking for younger kids — and a calm reset for parents, too.

Read and Ramble
Take story time outdoors with our Local Story Walk Trails Your Family Will Love roundup. These trails combine reading and movement — kids follow pages of a children’s book mounted along the path, turning each walk into an interactive adventure.

Play at Casco Village Park
The Casco Village Park Playground is a beautiful, family-friendly space with colorful structures, benches, and a safe layout for mixed-age play. Pair it with a stroll through town or a treat from a local bakery for an easy afternoon adventure.

Indoor Fun for Rainy Days

Bring a blanket and curl up with a new stack of picture books, or check your local branch calendar for seasonal events and early-literacy programs.
