Skylands Manor, with its English Jacobean architecture common in the English countryside 400 years ago, was designed by John Russell Pope for Clarence McKensie Lewis, a stockbrocker and civil engineer. Built in the 1920s, it is constructed of native stone and half-timbers. The weathered stone facade of this 44-room mansion blends into the landscape. The mansion contains rooms with antique paneling as well as new American Oak paneling and large windows, some of which contain 16th-century stained glass medallions. Moulded plaster ceilings and an elaborately carved staircase add the finishing touches to this impressive country house. Ringwood Manor, which was home for a succession of well-known ironmasters for nearly 200 years, sits comfortably on a low hill. Iron production in this area began in the 1740s. In the mid-19 century, Ringwood Manor was owned by Abram S. Hewitt, America's foremost ironmaster. Dedicated in 1984, the State Botanical Garden is the culmination of two eras of landscape architecture under the direction of Francis Lynde Stetson, owner of Skylands from 1891—1922. The garden contains an extensive variety of plants, including evergreens and deciduous trees and shrubs in specialty areas.

With its diamond-paned casement windows, clapboards weathered nearly black, and hewn overhangs, the Buttolph-Williams House harks back to the Puritan pioneering of New England during the 1600s. Although actually built around 1711, the house reflects the continuing popularity of traditional architecture. As a result it is considered the most faithful restoration of a 17th-century-style Connecticut Valley house. An array of colonial-era furnishings is on display. Highlights include a room designed and decorated by Katherine Prentiss Murphy, one of the 20th century's most renowned antiques collectors, and a kitchen with an enormous open hearth and an assortment of Colonial-era cooking implements.

The park overlooks the Petaluma River and San Pablo Bay from the east-facing slopes of 1,558-foot Mount Burdell. The name "olompali" comes from the Miwok language and may be translated as "southern village" or "southern people." The Coast Miwok inhabited at least one site within the area of the present-day park continuously from as early as 6,000 BC until the early 1850s. Olompali contains "kitchen rock," a large boulder used as a mortar in which early people ground acorns and seeds into a fine flour for food preparation. Many women would gather near such grinding rocks to prepare food and socialize.

La Cuesta Encantada, "The Enchanted Hill" high above the ocean at San Simeon, was the creation of two extraordinary individuals, William Randolph Hearst and architect Julia Morgan. Their collaboration, which began in 1919 and continued for nearly 30 years, transformed an informal hilltop campsite into the world-famous Hearst Castle—a 115-room main house plus guesthouses, pools, and eight acres of cultivated gardens. The main house itself, "La Casa Grande," is a grand setting for Hearst's collection of European antiques and art pieces. It was also a most fitting site for hosting the many influential guests who stayed at Hearst's San Simeon ranch. Guests included President Calvin Coolidge, Winston Churchill, George Bernard Shaw, Charles Lindbergh, Charlie Chaplin, and a diverse array of luminaries from show business and publishing industries.

The site offers exhibits, tours, a 40-min. film, living history presentations, educational programs, and occasional recreational and educational events.
