East of Jacksonville's skyscrapers and west of the beaches, this state park protects one of the largest contiguous areas of coastal uplands remaining in Duval County. The uplands protect the water quality of the Nassau and St. Johns rivers, ensuring the survival of aquatic plants and animals, and providing an important refuge for birds. Wildlife is abundant and ranges from the threatened American alligator to the endangered wood stork. Equestrians, hikers, and off-road bicyclists can explore five miles of multi-use trails that wind through the park's many different natural communities. The park has a canoe/kayak launch accessible by a 500 foot portage to the marshes. Located off I-95 or 9A, head east on Heckscher Drive. Turn north on New Berlin Road, then east on Cedar Point Drive. Turn north on Pumpkin Hill Road. Trailhead parking is approximately one mile on the left.

The creeks adjacent to Pumpkin Hill Creek Preserve State Park are crucial in maintaining a healthy habitat for plants and animals, and provide the paddling enthusiast hours of exploration through pristine estuarine habitats. Access to Pumpkin Hill Creek is available for canoes and kayaks via a hand launch area at the end of Pumpkin Hill Road.

There are three access points to unspoiled tidal creeks adjacent to park property. Whether fishing from the shore or a boat, these creeks have enormous potential for catching redfish, flounder, and speckled sea trout.
