If you need an open invitation to go explore a peaceful tree-lined lake in the summertime, consider yourself invited. Go see lower Mayer State Park from the top of Rowena Crest and soak in a view of the most beautiful lake around. Both are actually within Mayer State Park, but few people know that. From the top of Rowena, Mayer can be fully appreciated for its many amenities, including swimming, boating, fishing and picnicking
