Thank you for your interest in Members’ Day. The event is now sold out. Please visit the events page to explore other programs that may be of interest to you and will be free or discounted due to your membership with Natural Lands. We are so grateful for your generous support.

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.

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, farm fields, 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.

  • Event is rain or shine.
  • Please dress appropriately for the weather and for walking on uneven, and possibly, wet terrain.
  • Parking may be limited—we encourage carpooling. This is an open house-style event with activities being offered throughout the afternoon.
  • Please leave your four-legged friends at home.
  • All participants (adults and minors) wishing to ride the hot air balloon will be required to sign a liability waiver.
  • In the event of unsafe conditions that would prevent the balloon from flying, we will notify participant by email before the event.

Events may be cancelled due to inclement weather or low registration. In that case, we will make every effort to update our website and contact registrants. Note that we cannot offer refunds of paid registrations or ticket purchases, but rest assured that your donation will help us in our work to save open space, care for nature, and connect people to the outdoors.
