The bluffs are part of the Niagara Escarpment, a massive dolostone ridge extending from New York to Wisconsin.
The park provides protected nesting sites for the endangered peregrine falcon.
The steel observation deck is anchored into the rock, allowing it to hang out over the sheer drop-off.
The forest canopy is primarily composed of beech, maple, and hemlock trees.
Portions of the site are designated as a State Natural Area due to the presence of rare, ancient white cedar trees clinging to the cliff face.
Ellison Bluff State Natural Area features 100-foot limestone bluffs overlooking Green Bay. The site encompasses 174 acres of protected habitat, including a mature hardwood forest. A metal staircase and boardwalk lead visitors to a cantilevered observation deck extending over the cliff edge. The Niagara Escarpment serves as the geological foundation for the bluffs. The park provides critical nesting habitat for rare birds, including the peregrine falcon. Hiking trails wind through the dense woods, connecting to the central overlook. The area is managed by the Door County Parks Department and remains largely undeveloped to preserve its ecological integrity. Visitors can observe the transition from forest to lakefront cliff environments within a short distance.

Wear sturdy, closed-toe walking shoes to navigate the uneven forest trails.
Bring insect repellent during the warmer months, as the wooded areas attract mosquitoes.
The temperature at the cliff edge is significantly cooler than in the interior woods; bring a light outer layer.
Do not attempt to climb or scramble down the cliff face, as the limestone is unstable and dangerous.
Trails may be inaccessible or hazardous during deep winter snow conditions.
Stay on marked trails to protect fragile cliff-side vegetation; pets must remain leashed at all times.
