Land for life. Nature for all. It’s the heart of our mission. But we can’t succeed without member support.
You take care of us all year long. This is our chance to thank you.
Members are invited to appreciate all you make possible—miles of trails, unparalleled views, and dedicated care of the natural world that supports us all.
Mingle with friends and other Natural Lands members. Choose from a variety of activities—including guided hikes and strolls, family-friendly activities at Ollie Owl’s NaturePlayGround, an introduction to birding program, and hot air balloon rides featuring stunning views of the 1,282-acre preserve.
Together we have an impact. Today. And forever.
Day of activities and registration will be added soon. Please come back and visit this site for more details.
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.
