The prime spot for fishing in the lake is the Allen Branch area, located in the northern section of the park, where you'll find a boat launch and fish cleaning station. If you'd like to find a quieter spot to cast your line, head about a mile down the Illini Trail to a small fishing pond with its own pier.

Sailing and Boating

For a fee, you can use all of the marina's services from boat storage to showers and picnic tables. Motorboats, kayaks, canoes, paddleboards, and all other sorts of watercraft are welcome to use the lake as well. The park offers three public boat ramps.


If you're camping with children, one of the best ways to beat the heat is to take a dip in the pool. Located near the campground and camp store, the park features a public swimming pool. The pool is open and monitored by lifeguards all summer long, from Memorial Day to Labor Day. So don't forget to pack your swimsuit and sunscreen in your campervan.



Hikers can explore nine miles across seven trails, each providing a different experience of the park. The best ADA-accessible trails for leisurely strolls, nature viewing, and bird watching are the Bluestem Trail and the Wetland Educational Trail. The 1.5-mile Illini Trail is a lovely trek that will take you to a hidden fishing pond, which is a great fishing spot for children. The longest trail at the park also features a historic site. The three-mile Cherokee Trail passes by an early settler cemetery from the early 1800s. Please note that all hiking trails are closed during certain days of the week from November to January due to the pheasant hunting season.


Fifty acres of land are open to archery and shotgun hunting. Common game includes quail, dove, squirrel, waterfowl, and rabbit. Archery deer hunting is permitted, and pheasant hunting takes place from November to January every year. Hunters must pay attention to the appropriate hunting season, and make sure to follow all state and park regulations.


The park offers some of the most beautiful spots to enjoy a serene picnic with picturesque views of the lake.
