Brown's Woods, in West Des Moines, is the state's largest urban forest, encompassing 486 acres of mature oak and hickory trees. The area offers over 4 miles of moderate hiking trails, including the Gateway Trail (0.5 miles), Preparation Loop (0.5 miles), Wilderness Loop (1.4 miles), and North Loop (2 miles). These trails all traverse rolling hills and small streams in forested environment. The preserve also serves as a crucial stopover for migratory birds during spring and fall, attracting species such as warblers and vireos, making it a popular spot for birdwatching. This is also a popular spot with foragers; visitors are permitted to collect nuts, fruits, or edible mushrooms for non-commercial use, provided the plants are not harmed. However, activities like removing plants, hunting, trapping animals, and cutting wood are prohibited. Dogs are welcome but must be kept on a six-foot leash, and owners are reminded to clean up after their pets.
