Rockville Hills Regional Park

Rockville Hills Regional Park offers grassland, oak woodland, and rocky terrain in Fairfield.

Rockville Hills Regional Park

Shared trails provide options for walking and mountain biking through a varied open-space landscape. The park's natural setting rewards choosing a route suited to your time and ability rather than treating every trail as a gentle urban stroll.

A valid entrance pass and personal identification are required while visiting. Check current fire-weather and trail conditions before traveling, since red-flag warnings or wet weather can close the park. Carry water, give other trail users room, and plan to leave before sunset when the park closes.
