ChesLen Preserve is the largest privately owned nature preserve open to the public in Chester County. Miles of marked hiking trails lead visitors through shady woodlands, flower-filled meadows, fields of corn and soybeans, and stream valleys.

Visitors can also explore Ollie Owl’s NaturePlayGround, where young explorers can climb logs, build stick tee-pees, hunt for bugs, explore small streams, and get a little dirty, tired, and inspired. Free play is encouraged and is a great way for kids to gain an appreciation for nature.
