The park contains some of the highest elevations within the Ann Arbor city limits.
It is managed as a natural area, meaning invasive species control and native restoration are prioritized over landscaping.
The landscape is primarily second-growth oak-hickory forest, which is rare in urban settings.
The park is adjacent to the much larger Kuebler Langford Nature Area, creating a massive contiguous green space.
The area is home to several species of spring ephemerals, including trillium and trout lilies.
Bird Hills Nature Area is the largest city-owned park in Ann Arbor, covering 161 acres of rugged, glaciated terrain. It features a dense network of hiking trails that wind through steep hills, ravines, and woodlands. The area protects a significant portion of the Huron River watershed's forest canopy. Hikers frequently encounter varied topography characterized by sandy soils and kettle holes formed by retreating glaciers. It serves as a vital corridor for local wildlife, including deer, wild turkeys, and numerous migratory bird species. The trails are unpaved and primitive, maintained primarily to support passive recreation like walking and nature study.
The ridge overlooks providing elevated views of the forest canopy, especially during peak autumn color changes.
Wear sturdy, waterproof hiking boots as trails can become muddy and steep after rainfall.
Carry a digital or paper map, as the trail network is extensive and lacks directional signage at many intersections.
Use insect repellent during the summer months to protect against mosquitoes and ticks.
Attempting to navigate the steeper sections during or immediately after heavy rain due to significant erosion and slippery slopes.
Open daily from dawn to dusk; no lighting is provided on trails.
Keep pets leashed at all times, stay on marked trails to protect sensitive flora, and pack out all trash.
