Lake Hartwell State Park is a park focused on fishing.  The 56,000-acre Lake Hartwell maintains a reputation for top-flight angling, including for striped and hybrid bass, largemouth, crappie, bream and catfish.
In addition to lake access, there is a park store, hiking, camping and unique, affordable one-room camper cabins. They feature bunk beds, a porch and electricity but no running water or bathrooms. The campground facilities are nearby.
