Timber Hills, PA

Timber Hills is a Lebanon County census-designated place in southeastern South Londonderry Township, with 360 residents in the 2010 census. It lies beside Mount Gretna, with Conewago Lake in the southern part of the community and the Susquehanna River region beyond the hills. Pennsylvania Route 117 and local roads connect Timber Hills with the Mount Gretna borough and the Lebanon Valley. The place is a wooded lakeside section of a township whose recreation and historic districts overlap.

Conewago Lake and Mount Gretna carry the clearest local story. The man-made lake sits just north of Mount Gretna and is part of a landscape that includes the Pennsylvania Chautauqua Historic District, campmeeting grounds, and the old resort town. Timber Hills appears within that historic setting alongside Conewago Hill and Timber Bridge. The CDP is tied to a specific southern Lebanon County pattern: lake water, wooded hills, summer gathering grounds, and the road network around Mount Gretna. Timber Hills is a Pennsylvania place where a small residential community shares a landscape built around lake and Chautauqua history.
