Goll Woods Nature Preserve is a 321-acre natural area in the U.S. state of Ohio. It is managed by the Ohio Department of Natural Resources and is located in Fulton County, about 10 miles south of Archbold. The preserve contains one of the few remaining examples of the Great Black Swamp, a once vast wetland that covered much of northwestern Ohio.

Visitors to Goll Woods Nature Preserve can enjoy hiking, birdwatching, and nature photography. There are two miles of trails that wind through the woods and along the banks of the Tiffin River. Points of interest include the old-growth forest, which contains some of the oldest trees in Ohio, and the boardwalk over a wetland area, which offers a unique opportunity to observe a variety of plant and animal species.

One interesting fact about Goll Woods is that it is home to several species of rare and endangered plants and animals, including the Indiana bat and the eastern massasauga rattlesnake. The preserve also has a rich cultural history, with evidence of Native American habitation dating back thousands of years.

The best time of year to visit Goll Woods Nature Preserve is in the spring and fall, when the weather is mild and the leaves are changing colors. However, the preserve is open year-round and offers different experiences throughout the seasons. Visitors in the winter may be able to see bald eagles and other winter wildlife, while those in the summer can enjoy the shade of the forest canopy and the refreshing coolness of the Tiffin River.
