Since 1925, the Forest Preserve District has worked to preserve and restore Kane County 's natural areas, improve wildlife habitat, and enhance the quality of life for all Kane County residents. We invite you to visit the forest preserves and enjoy a quiet walk, embark on a camping weekend, picnic with friends and family, learn about nature, birdwatch, fish, golf, ride, volunteer, or simply experience the wonder of our more than 23,000 of acres of woodlands, wetlands and prairies. No matter the time of year, there 's plenty to see and do in your Kane County forest preserves.
