Covid-19 Update October, 2020

In a continued effort to maintain staff and visitor safety during the current COVID-19 circumstances, our buildings will remain closed to the public, unless otherwise specified during Special Events and School tours. During this time we will be focusing on exhibit redesign, program development, and new experiences for the future. However, our Grounds and Gardens are open daily from dawn to dusk, and parking is free. Walking tours and Childrens Explorer Packs are available near all parking areas, self-guided Interpretive wayside panels around the site give a wealth of information, and several hiking trails and open areas are available. When visiting please continue to follow CDC and local health guidelines and remain safe. Thank you for your consideration, and understanding.

For more information, please contact Matthew Wedd at or call at 717-328-2800 and leave a voicemail.
