Last Updated on: 18th January 2023, 08:29 am

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.

Trione-Annadel History

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.

Arrowheads can still be found in Trione-Annadel State Park

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.

How to Get to Trione-Annadel State Park

Located along the southeast border of Santa Rosa, there are limited ways to gain access to the park. The main entry point can be found by traveling east along Montgomery Drive and then heading south onto Channel Drive. You’ll travel about ¾ of a mile down until you find the Cobblestone Trailhead, leading directly into the main area of the park.

An alternate route can be taken from the city of Kenwood, where you’ll be able to start at the Lawndale Road Trailhead and head north into the Trione-Annadel State Park.

There is space to park your vehicle along the entrance road and there is also a parking lot once you enter the state park area. Keep in mind, no automobiles are allowed past these points.
