Please Recreate Responsibly

“Know before you go.” Remember to plan ahead, know your limits, and do not take unnecessary risks.
Be courteous and inclusive. People have different reasons for visiting shared public lands and everyone deserves respect and courtesy while recreating outdoors.
Enjoy and protect shared public lands. Remember to “Leave No Trace” and pack out all trash and dog waste. Know which areas allow dogs on trails and which do not.
Do not park illegally at trailheads. Make a backup plan in case a trailhead is full. Take shuttle services to popular trailheads and recreation areas.
Stay on trail and walk through mud. Step onto a bare spot or rock if you need to step off trail. Once others pass, immediately step back on trail.
