This preserve is within the Sugar Grove Region of the Hocking Hills. A relatively strenuous hike to the top of the dry ridgeline affords a view of the Hocking River Valley to the east. This dry ridge forms a horseshoe shape, supporting a significant chestnut oak community with Virginia and pitch pine, sourwood and a well-developed heath layer of mountain laurel, blueberry, deerberry, and state listed flame azalea (Rhododendron calendulaceum). The cooler north facing slopes below the cliff lines form an environment better suited to eastern hemlock, black birch and another state listed member of the heath family - the great rhododendron (Rhododendron maximum). This is likely the home of the largest native population of this native rhododendron in Ohio. Peak blooming is typically during late June and early July.

Rhododendron Cove is wonderful preserve small in size but large in beauty located in the northern Hocking Hills near the village of Sugar Grove. The preserve protects interesting geological features and a rich diversity of flora, most notably the largest known concentration of the state endangered great rhododendron. Hiking here is reminiscent of hiking in the Appalachian Mountains.
