In light of the damage from winter storms, visitors are encouraged to exercise caution around large trees and bluff-tops. To stay on top of all park and trail closures, visit the San Mateo County Parks advisory page. In recent years, San Mateo County Parks has increased ways for dogs and their humans to access a variety of recreational opportunities. Here is the updated list of dog-friendly parks and trails available to you and your leashed canine companion. Please note that some of these areas represent a portion of the park. For example, at the Fitzgerald Marine Reserve, dogs are not allowed down by the tide pools, but can enjoy the Dardenelle Trail.
