Trail Use Rules

It is the law

Stay on trails.

  1. Yield to hikers, equestrians and all traffic going uphill. You never have the right of way, so be prepared to stop at any time.
  2. Speed limit on trail is 15mph. Manage your speed. Keep in mind that you are not alone on the trail and that you might have to stop at any time.
  3. Don’t wear ear phones in both ears. You must be aware of your surroundings and able to hear what is happening.
  4. Do not litter.
  5. No fire of any kind.

To help us keep the trails open

  1. Be nice to others users. “Hello” and a smile can change everything.
  2. Wear a bell. The bell will announce your presence on the trail and helps avoid surprising and upsetting other users. Same for animals.
  3. Stop for horses, greet the rider, and wait until s/he tells you it is OK to pass. Horses can behave unpredictably when spooked by a bike, putting both you and the rider in danger. Speaking to the rider lets the horse know you are human and not a predator.
  4. Be very careful in blind turns.
  5. Don’t be a skidiot. Skidding damages the trail and scares other users.
