Open to visitation one day per year, the Sacred Oak in Oley, Pa., will be available to be seen on Saturday, June 7. A chinkapin oak of unknown precise age, yet widely believed to be 500-plus years old, and over 20 feet in girth is among the most famous trees in the state and stands on private land off Friedensburg Road in Oley Township, Berks Co. Representing a success story in how public and private partnerships can work, the tree, with roped-off trunk to avoid human contact, is only available for the public to visit, present day, on one designated day a year by the township. The public hours will be from 9 a.m. to 2 p.m., rain or shine. To learn more, the public is encouraged to contact the Oley Township office.
