Matanzas Inlet

Summer Haven is an unincorporated community in southeast St. Johns County, Florida, United States, located just south of the Matanzas Inlet, on a narrow strip of land between a shallow marsh and the Atlantic Ocean.Summer Haven is a small beach resort which began with cottages used by farmers. It consists of approximately 60 structures, mostly single family homes.Around 1890, Thomas A. Mellon started vacationing in Summer Haven. Eventually the community attracted other well known people, including Cornelius Vanderbilt Whitney, Owen D. Young, and author Marjorie Kinnan Rawlings.After severe nor’easters in 1962, Summer Haven was declared a disaster area, and the U.S. Army Corps of Engineers constructed an 1,800-foot granite revetment along the northern portion. After Hurricane Dora in 1964, the existing revetment, which fronts the majority of the upland development in the reach, was extended by an additional 1,070 linear feet. South of the revetment, development is limited to one row of single-family residences. When possible, St. Johns County has been purchasing structures and lands in this southern area and not allowing further development.

Fort Matanzas National Monument (Spanish: Fuerte Matanzas) was designated a United States National Monument on October 15, 1924. The monument consists of a 1740 Spanish fort called Fort Matanzas, and about 100 acres (0.4 km2) of salt marsh and barrier islands along the Matanzas River on the northern Atlantic coast of Florida. It is operated by the National Park Service in conjunction with the Castillo de San Marcos National Monument in the city of St. Augustine.

Faver-Dykes State Park is a Florida State Park located 15 miles south of St. Augustine, near the intersection of I-95 and US 1, and bordering Pellicer Creek, a designated state canoe trail. Activities include fishing, picnicking, boating, canoeing, camping and wildlife viewing. Among the wildlife of the park are white-tailed deer, bobcats, and river otters. There are many birds in the park, including bald eagles, falcons, and hawks, as well as egrets, wood storks, white ibis, wild turkeys, and herons.

Marineland of Florida (usually just called Marineland), one of Florida's first marine mammal parks, is billed as "the world's first oceanarium". Marineland functions as an entertainment and swim-with-the-dolphins facility, and reopened to the public on March 4, 2006 (charging the original 1938 admission price of one dollar). In 2011, the park was purchased by the Georgia Aquarium for a reported $9.1 million.

Fort Fulton was established on February 21, 1840, between Old Kings Road and Pellicer Creek (west of present-day U.S. Highway 1) in present-day Flagler County, Florida. A January 17, 1840 article in the Florida Herald of St. Augustine stated, "Can anyone inform us why the Mounted Volunteer Company, raised in this city, and now stationed at Hewlett’s [Hewitt’s] Mill, is weakened by a detail of ten men subject to the order of the city council, and kept in town idle." This article suggests that Fort Fulton was most likely manned with militia volunteers since it was the only military post in the general area of Hewitt's Mill (which was located only about 1500 feet southwest from where Fort Fulton was built). Hewitt's Mill was a sawmill built in 1768 by John Hewitt on his 1,000-acre plot of land in St. Johns County. This sawmill is known to have supplied many wooden building materials to the St. Augustine area and surrounding plantations.

The town of Marineland was established in 1940 and is in Flagler and St. Johns counties, Florida, United States. The population was 16 in the 2010 census. Marineland is located 18 miles (29 km) south of St. Augustine along Route A1A. The Marineland marine park and the town of Marineland have become synonymous, however many do not realize that Marineland is a town in its own right. Like all proper municipalities, Marineland has its own local governing body complete with a mayor and city council board that meets monthly to discuss the town's affairs. The town shares a ZIP Code with St. Augustine Beach. The town of Marineland got its start when the Marineland Dolphin Adventure opened on June 23, 1938, as Marine Studios, a facility designed for Hollywood filmmakers to create underwater footage for motion pictures and newsreels. Popularly known as the "World's First Oceanarium," Marine Studios was the premier destination to allow the general public to experience marine life up-close. Because of their proximity, the local businesses share close partnerships and vision. The town of Marineland is a hub of research and conservation and is set in the middle of the GTM-NERR (Guana Tolomato Matanzas National Estuarine Research Reserve), local businesses and foundations have close working relationships including Mobius Marine, Inc., Ripple Effect Eco Tours, Marineland Marina, Marineland Dolphin Adventure, University of Florida Whitney Laboratory, the Florida Master Naturalist Program, the southern facility for the GTM NERR, and Washington Oaks Gardens State Park and Faver-Dykes State Park. The Flagler County portion of Marineland is part of the Deltona–Daytona Beach–Ormond Beach, FL metropolitan statistical area, while the St. Johns County portion is part of the Jacksonville Metropolitan Statistical Area.

Pellicer Creek is a stream in the U.S. state of Florida. It is a tributary to the Matanzas River, and delineates the border between St. Johns and Flagler counties in the northeastern part of the state. The creek begins as a blackwater stream in the swamps west of Interstate 95, and meanders eastward into the Matanzas River; it is part of Florida's Designated Paddling Trail System.Pellicer Creek was named after Francisco Pellicer, an early Spanish settler. The waterway was formerly called Woodcutter's Creek, along which lumber and turpentine from a sawmill owned by British master carpenter John Hewitt were transported to the Matanzas River and then northward to St. Augustine. In 1770, Hewitt had purchased 1,000 acres of land near the Kings' Road, where he built his water-driven mill, in operation from 1770 to 1813.
