The park contains a specific geological formation called an esker, a long winding ridge of stratified sand and gravel deposited by glacial meltwater.
Lake Góreckie is home to a small, uninhabited island known as Zamkowa Góra, which features ruins of a 19th-century romantic castle.
The park serves as a refuge for the protected hermit beetle, an endangered species in Europe that thrives in the park's old-growth deciduous trees.
More than 200 species of birds have been recorded in the park, making it a critical site for regional ornithological research.
The park's unique microclimate, combined with its kettle-hole lakes, supports relict flora species dating back to the post-glacial period.
Greater Poland National Park (Wielkopolski Park Narodowy) is a protected area situated south of Poznań, defined by its unique post-glacial landscape and dense forests. The park covers approximately 7,500 hectares, characterized by a complex network of over 10 post-glacial lakes. The Osowa Góra hill provides the highest point, offering panoramic views over the surrounding moraine terrain. Geologically, the area features numerous kettle holes and eskers formed during the last glacial period. The park's diverse ecosystem includes pine-dominated forests, oak-hornbeam stands, and aquatic habitats. It serves as a significant site for biodiversity, particularly for avian species and protected insects like the hermit beetle. Multiple hiking and cycling trails crisscross the park, connecting historical points of interest and nature reserves. The visitor center is located in Jeziory, housed within an 18th-century palace complex.

Bring a high-quality insect repellent, as the lake-dense landscape can result in significant mosquito activity during humid months.
Use the dedicated wooden viewing platforms around the lakes to avoid damaging protected shoreline vegetation.
Carry a physical map or GPS device, as mobile signal can be inconsistent in the deeper forest sections.
Do not attempt to swim in lakes marked as nature reserves, as unauthorized entry is strictly prohibited to preserve water quality.
Stay on marked trails to protect fragile post-glacial soil; keep dogs on a leash at all times; noise restrictions apply to protect local wildlife.
