Biddeford grew around big mills on the Saco River and now has a lively downtown full of good food. It sits close to some of Maine's best sandy beaches.
You can splash at Biddeford Pool beach, ride the summer trolley, and taste treats from the many shops in the old mill district.
The huge old brick mills are now filled with bakeries, cafes, and art studios. It is a cheerful place to wander and snack.
Biddeford Pool and nearby sandy shores are perfect for swimming and finding seashells. The ocean breeze keeps things cool in summer.
