Baldpate Mountain rises in western Hopewell Township, New Jersey, near the Delaware River, within the Sourlands upland region. As the highest peak in Mercer County, it stands out as a prominent natural landmark in this part of the state. Most of the mountain lies within the county-owned Ted Stiles Preserve, which helps protect it as preserved open space. Its significance rests both in its physical prominence and in its conservation, linking the landscape of western Hopewell Township to a broader effort to retain important natural land in New Jersey.
