Trione-Annadel State Park

We don't rate places, roads or trails as safe or unsafe: crash counts can't say how risky a ride is, and places riders like draw more riders, so they see more crashes. Police crash reports cover public roads, so falls on trails aren't in them. The records here are also incomplete: most nearby reports are filed under Santa Rosa, where only 11% of reported bike crashes have a map location, so the numbers here are too low. What the records show: no bike crashes were reported within a mile of Trione-Annadel State Park from 2021–2025.

No spot within a mile of Trione-Annadel State Park has 3 or more reported bike crashes.
