This park is part of a nationally recognized historic landmark and can be found adjacent to the extant portion of one of California's 21 Spanish-era mission church sites. The park and its Plaza represent what was once the "town square" of the largest town in central California and a vital crossroad for travel between northern and southern California. In the park visitors can gain an appreciation of California peoples, from Native Americans, through the Spanish and Mexican cultural influences, right up to the American period in the late 19th century. The park site includes several structures built in the 1800s. These include the four main historic structures of the Plaza Hotel, the Zanetta House/Plaza Hall as well as Plaza Stables, and the newly reopened Castro-Breen Adobe with colorful and informative exhibits to help create a learning environment for people of all ages. Many of the interiors are arranged as furnished vignettes. The park also features a blacksmith shop, the historic jail, and an early American settler's cabin.

The park offers exhibits, tours, and occasional living history events.

The 2,546-acre McConnells Mill State Park preserves an 1868 gristmill and the Slippery Rock Creek Gorge, which was formed as prehistoric glacial lakes drained. The gristmill is operational, and was one of the country's earliest rolling mills. It harnessed waterpower to grind buckwheat, corn, wheat, and oats into flour.

The site offers guided hikes, night programs, school activities, guided mill tours, picnic areas, and charcoal grills. The park requests that visitors remain on the trails, and refrain from swimming. Please avoid bringing firewood into the park, as it can allow for the entry of invasive species.

Visitors to the site can receive an interactive history lesson at the visitor's center, or just walk the Fort and ramparts for a view of the Thames River. The fort contains informative markers and displays, a touchable cannon and artillery crew display, and gun emplacements. The fort interior features 19th-century restored living quarters, a mock laboratory, and a 1950s era office furnished to resemble a research and development lab at the facility. The visitor center contains state-of-the-art multimedia theaters, computer touch-screen interactive exhibits, 3-D models, and extensive graphics and text panels. The center depicts over 225 years of military history and technological advances from the Revolutionary War to the Cold War. Some of the main display themes include the September 6, 1781 attack by the British under the command of Benedict Arnold, the U-boat menace during World War II, and the anti-submarine efforts during the Cold War.

The site of Barnegat Lighthouse on the northern tip of Long Beach Island in Ocean County was regarded as one of the most crucial "change of course" points for coastal vessels. Vessels bound to and from New York along the New Jersey coastline depended on Barnegat Lighthouse to avoid the shoals extending from the shoreline. The swift currents, shifting sandbars, and the offshore shoals challenged the skills of even the most experienced sailor. The park is included as a maritime site on the New Jersey Coastal Heritage Trail.

The site offers exhibits and tours.

The Farmington Historic Plantation, built between 1815 and 1816 as a working hemp plantation, was home to John (1772-1840) and Lucy Fry (1788-1874) Speed. Today, the Federal-style home is furnished to an 1830s appearance, the period of time when the plantation was at its peak prosperity; and the furnishing of the home was largely guided by Speed's 1940 home inventory. The number of slaves on site varied between 45 and 64 during the plantation's operation, while the average state slaveholder owned only 5 individuals. Reconstructed structures on the grounds include the summer kitchen and cook's quarters and a springhouse. The grounds also hold a blacksmith shop, never originally on the plantation. The plantation is relevant to slavery, the Civil War, period politics, gender roles, and John Speed's close friendship with Abraham Lincoln.

The plantation offers period rooms, periodic re-enactments offering living history interactions, educational programming in compliance with state educational standards, quill pen writing, a scavenger hunt, 19th-century games, and cornhusk doll making. The website offers pre-visit information packages for teachers. Educational programs are available to all students, including home school students.

The home also served as Winchester, Virginia's first Quaker meeting house. On-site, one can also find mill stones and a log cabin, which is more typical of early settlers' dwellings.
