/ref> Visitors can enjoy the park's diverse wildlife and scenery during any time of the year but are perhaps most rewarded from April through June when most wildflowers are in bloom. The park has gone through two Wildfires in its history, the 2017 Nuns fire that burned the majority of the park and the most recent Glass fire in 2020.
Plant community, Plant communities include California oak woodland, riparian zone, riparian woodland, Douglas fir forest, chaparral, grassland, and marsh. The dominant plant community is the oak woodland, which has a Canopy (forest), canopy of Quercus agrifolia, coast live oak, Quercus garryana, Garry oak, Quercus kelloggii, black oak, Arbutus menziesii, Pacific madrone, Acer macrophyllum, bigleaf maple, and Umbellularia, California laurel. Quercus chrysolepis, Canyon live oak occurs in Swale (landform), swales and stream, creeks. In the oak woodlands, the dominant understory plants are native bunchgrasses, Heteromeles, toyon, rubus, wild blackberry, Baccharis pilularis, coyote brush, and Toxicodendron diversilobum, western poison-oak. The latter covers nearly one quarter of the understory in the park. Douglas fir occurs in some of the steeper, cooler riparian zones and on north-facing slopes.
Common animals in Annadel include black-tailed deer, western gray squirrel, raccoon, skunk, and opossum. Bobcat and mountain lion are occasionally observed. There are many bird species, including the California scrub jay, Steller's jay, acorn woodpecker, black phoebe, and dark-eyed junco. In moist areas, amphibians such as the rough-skinned newt can be found.
The southern reaches of Annadel are drained by Yulupa Creek and other tributaries of Sonoma Creek, while the northern flanks are part of the Santa Rosa Creek Drainage basin, watershed. Eastern slopes are drained by Yulupa and Sonoma Creeks, while the western slopes are part of the Spring Creek (Sonoma County, California), Spring Creek watershed. Many of Annadel's streams are dry in the summer, because rainfall is highly seasonal, with most of the approximately of annual precipitation occurring between October and April. Ledson Marsh, which drains into Yulupa Creek, retains some smaller pools of water throughout most of the year. The highest elevation in the park is the top of Bennett Mountain, .

The Southern Pomo and Southern Wappo peoples inhabited these lands in prehistoric times. No full-scale villages have been discovered within the park boundaries. This site was valuable to the Native American tribes as a source of obsidian, which they used to make scrapers, knives, arrowheads, and spearheads. Archaeological evidence suggests they used the area as a quarry at least as far back as 3000 years. Human use and settlement of this area changed markedly in the late 18th century when the Spanish colonization of the Americas, Spanish came to this region. Cattle ranching and farming gradually replaced hunter-gatherer, hunting and gathering.
In 1837, Annadel was part of the Rancho Los Guilicos Mexican land grant. In 1848 the lands of Annadel were purchased by Scottish immigrant William Hood, for whom nearby Hood Mountain was named. In the late 19th century, sheep and cattle grazing was superseded by quarry uses. There was considerable demand for cobblestone material when many west coast cities were being developed, and especially in the reconstruction of San Francisco after the 1906 San Francisco earthquake. Cobblestone quarry operations were a major source of revenue to the Wymores and the Hutchinsons who were the principal land owners in this area around the year 1900. The park derives its name from Annie Hutchinson, since this locale was once termed "Annie's Dell". In the early 1900s, author Jack London settled nearby in these same Sonoma Mountains, and he based much of his writings on these mountains that he loved.
Demand for cobblestone subsided around the year 1920, since owners of the newly invented automobile expected a smoother ride than that derived from cobblestone streets. Joe Coney began to accumulate land holdings in this area during the 1930s. He used the land for agricultural purposes until the late 1960s, though he also mined perlite, an obsidian product used in the manufacture of certain insulation products. Annadel became part of the California State Park system in the year 1971.
The site of what became Trione-Annadel was being eyed for residential development when Henry Trione and hunting buddy Joe Long of Long's Drugs put together a $5 million package that led ultimately to the site's protection as a park. Trione built his home on the hillside adjacent to Annadel. In 2012, he pitched in another $100,000 to keep the park running under county administration at a time when Annadel and dozens of other parks statewide were threatened with closure because of a budget crisis. It was due to these philanthropic efforts that the State of California ruled in July 2016 to officially change the name to Trione-Annadel State Park.

action formed the massif which comprises the park of today. Elevations in Annadel range from about above sea level. Slopes within Annadel commonly range from 15 to 30 percent, but it is not uncommon to encounter slopes up to 70 percent on steep slopes above drainages which are covered in douglas fir forest. One of the major soil associations within the park is Goulding cobbly clay loam, which contains roughly 25 percent cobblestones with some basaltic exposures, evidence of the volcanic origins of the Sonoma Mountains. Typical soil depths are . Much of the soil type in the Yulupa Creek riparian zone consists of Laniger loam, with rhyolite outcrops, another relic of the igneous history.
