Frontenac State Park's diverse landscapes -- prairie, bluffs, hardwood forests and floodplain forests -- offer a rich range of landscapes for all manner of wildlife.
Here are some that an attentive (and reasonably quiet) visitor might see on a visit to the park: Whitetail deer. Coyotes. Foxes. Beavers. Muskrats. Raccoons. Badgers. Pocket gophers. Skunks. Squirrels. Field mice. Native toads, frogs and turtles.
Pleasant Valley Lakelet, which park visitors can explore with canoes provided by the park, has a variety of game fish. Lake Pepin, which spreads out below the bluffs, is an angler's paradise.
They hide well, so you're not likely to see them, but the park is also home to a number of beneficial and nonvenomous snakes, including the fox snake and the gopher snake and lots of small garter snakes. And yes, it's also home to the endangered timber rattlesnake. They are rare and elusive, and you're unlikely to see one, but if you do, simply stay out of its way. Like all native wildlife, it has an important place in the park's ecosystem.
