Hamilton Branch State Park is a South Carolina state park near Plum Branch on a 731-acre peninsula in Lake Strom Thurmond. Added to the South Carolina State Park Service in 1972 on land leased from the United States Army Corps of Engineers, it is centered on public access to the lake. Its facilities include lakefront campsites, picnic shelters, a playground, and two boat ramps. A short bike trail links the park to the Steven's Creek Bike Trail, and the area is also popular for geocaching, fishing, and bird watching.
