This event is SOLD OUT. In 2010, the Trust protected Cathedral Meadows, 30 acres of meadows, hedgerows, a shallow pond, and a section of the Cairn Run stream in Bryn Athyn.  Accompany a Pennypack staff member on an autumn walk from the Visitor Center to ramble through the property, which is accessible only via guided tours.  There is only a rough trail through Cathedral Meadows, and much of the walking there will be through tall grasses, so dress appropriately. Members free; non-members $10.
