This park is located high atop the bluffs that characterize the Green Bay side of the Door County Peninsula. Spectacular views of Green Bay and the bluffs of the peninsula to the southwest can be seen from atop the rocky escarpment.
The month of May sports many emerging wildflowers. One of the most prolific and the first to catch my eye was the large flowered trillium. Picking Trillium for their flower can seriously injure the plant. The three leaves (more correctly leafy bracts) below the flower are the plant's only ability to produce food stores and a picked trillium can take many years to recover. For this reason in many areas they are protected on public lands and it is illegal to pick or transplant them.
Ellison Bluff rises about 180 feet above the water level of Green Bay. None of the bluffs display the character of the shoreline any better than Ellison Bluff.
The view from the observation point is southwestward along the slope of the Niagara Escarpment. The full height of the escarpment is not visible, however, because the lower part is submerged beneath the water of Green Bay. Water depth in the vicinity of Ellison Bay is about 100 feet, thus in some places the full height of the escarpment reaches as much as 300 feet. Some landforms visible from this vantage point are Chamber’s Island, Horseshoe Island, and the Strawberry Islands. Across Green Bay and to the west and northwest is the Upper Peninsula of Michigan, Horseshoe Island, and the Strawberry Islands.
