As one of the top places to visit in Santa Rosa, Trione-Annadel State Park has captured thousands of people’s attention as a great spot for hiking, fishing, and so much more.
This ultimate guide includes key details about the best things to do in Trione-Annadel State Park and what the area has to offer. Anyone thinking about visiting this fun location should take a look to get a headstart on their planning.
About 3,000 years ago, what is now known as the Trione-Annadel State Park area was once controlled and occupied by two indigenous tribes known as the Wappo and the Pomo people. Its main resource to these groups was the high amount of obsidian that could be found and carved into various tools like knives, spearheads, and arrowheads. As Spanish settlers arrived, the area was converted into farmlands and ranching space for cattle.
A Scottish immigrant named William Hood (the namesake for the nearby Mount Hood) purchased the land in the mid-1800s and converted it into a quarry that mainly produced cobblestone. Thanks to this development, the area played a pivotal role in the rebuilding of San Francisco after the major earthquake that hit in 1906.
The land was exchanged a few more times during the 1900s until a man named Henry Trione bought the area and established it as the protected Trione-Annadel State Park we know today.
