Palo Alto Open Space preserves have ordinances and regulations that are designed to keep everyone safe and to have an enjoyable experience. Below are general reminders for some of the most common rules that need to be followed. Failure to observe these rules makes you subject to citation by the rangers.

Feel free to call Foothills Nature Preserve (650-329-2423) or Baylands (650-617-3156) for clarification of any of these rules.

Just remember that you are in a nature preserve. Leave it better than you found it for others to enjoy after you.
